    2011-01-01

    Consistently superb observing conditions are crucial for achieving the scientific objectives of a telescope. Submillimeter astronomy is possible only at a few exceptionally dry sites, notably Mauna Kea, the Antarctic plateau, and the Chajnantor region in the high Andes east of San Pedro de Atacama in northern Chile. Long term measurements of 225 GHz and 350 \\mu m atmospheric transparency demonstrate all three locations enjoy significant periods of excellent observing conditions. Conditions on the Chajnantor plateau and at the South Pole are better more often than on Mauna Kea. Conditions are better during winter and at night. Near the summit of Cerro Chajnantor, conditions are better than on the Chajnantor plateau.

  2. Observing Projects in Introductory Astronomy

    2016-01-01

    Introductory astronomy classes without laboratory components face a unique challenge of how to expose students to the process of science in the framework of a lecture course. As a solution to this problem small group observing projects are incorporated into a 40 student introductory astronomy class composed primarily of non-science majors. Students may choose from 8 observing projects such as graphing the motion of the moon or a planet, measuring daily and seasonal motions of stars, and determining the rotation rate of the Sun from sunspots. Each group completes two projects, requiring the students to spend several hours outside of class making astronomical observations. Clear instructions and a check-list style observing log help students with minimal observing experience to take accurate data without direct instructor assistance. Students report their findings in a lab report-style paper, as well as in a formal oral or poster presentation. The projects serve a double purpose of allowing students to directly experience concepts covered in class as well as providing students with experience collecting, analyzing, and presenting astronomical data.

    Wehinger, P. A.; Wyckoff, S.; Matlaga, D.

    1994-12-01

    We report on a program of observational astronomy laboratory exercises employing CCDs with small telescopes. The lab exercises are inquiry-based to develop critical thinking skills. We are using a thermoelectrically cooled CompuScope CCD (512 x 768 pixels, 14 bits deep) with an automated filter wheel and CompuScope's Personal Observatory 32-bit image processing software. Sample lab exercises will be presented. We intend to create an image database of observations obtained by undergraduate students which will be available over the Internet.

    2009-01-01

    A partnership has been established between South Carolina State University (SCSU, a Historically Black College/University), the National Optical Astronomy Observatory (NOAO) and Clemson University (CU) under an award from NSF's "Partnerships in Astronomy and Astrophysics Research and Education (PAARE)" program. The mission of POCA is to develop an effective, long-term partnership that combines the strengths of the three institutions to increase the scientific and educational output of all the partners with special emphasis on enhancing diversity in the field of astronomy. Components of the program include enhancing faculty and student research in astronomy at SCSU, recruiting and retaining underrepresented minority students into the field, outreach through planetarium programs and museum exhibits and developing web based resources in astronomy education. Activities in the first year of the program are discussed. We have begun developing and testing several new astronomy laboratory exercises. Our first summer internship program has concluded successfully. With PAARE scholarship money, we are now supporting four physics majors at SCSU who have chosen the astronomy option (concentration) for their degree. SCSU undergraduates have acquired observing experience on the KPNO Mayall 4-meter telescope under the guidance of faculty and graduate students from CU. NOAO astronomers have collaborated with SCSU faculty to begin a research program that studies RV Tauri stars. Funds from PAARE are supporting follow-up research to a just-completed doctoral dissertation by E. A. Mayo described elsewhere in these proceedings. Future plans for graduate fellowships and related activities are discussed in addition to summer internships for POCA undergraduates at CU and NOAO. Support for this work was provided by the NSF PAARE program to South Carolina State University under award AST-0750814.

  6. The Internet Telescope: Remote Observing for the City Astronomy Class

    Science.gov (United States)

    Gehret, Lor; Winters, Wayne; Coberly, Steven

    The Latin School of Chicago is a college preparatory day school that involves its students in a number of astronomy initiatives. Here we report on our high school students' use of the New Mexico Skies Internet telescope. Using a Web browser, our astronomy students are able to control a Celestron C-14 coupled with a CCD camera to image deep sky objects. In Chicago, using the Internet telescope teaches students how to request time on a shared instrument and how to plan an observing program, and it provides many varied independent study project and classroom options. Students use this instrument during our spring astronomy project week trip, when they travel to live and work at the New Mexico Skies Guest Observatory to learn observational astronomy, remote observing, and CCD imaging. Other remote observing programs that provide similar options are referenced, some with different or multiple instruments, some with limited access, and some with open access. Sample student images taken with the New Mexico Skies Internet telescope are included.

  7. Optical, infrared and radio astronomy from techniques to observation

    CERN Document Server

    Poggiani, Rosa

    2017-01-01

    This textbook presents the established sciences of optical, infrared, and radio astronomy as distinct research areas, focusing on the science targets and the constraints that they place on instrumentation in the different domains. It aims to bridge the gap between specialized books and practical texts, presenting the state of the art in different techniques. For each type of astronomy, the discussion proceeds from the orders of magnitude for observable quantities that drive the building of instrumentation and the development of advanced techniques. The specific telescopes and detectors are then presented, together with the techniques used to measure fluxes and spectra. Finally, the instruments and their limits are discussed to assist readers in choice of setup, planning and execution of observations, and data reduction. The volume also includes worked examples and problem sets to improve student understanding; tables and figures in chapters summarize the state of the art of instrumentation and techniques.

    2016-01-01

    During the period between Fall 2014 and Summer 2015, the International Astronomical Union reorganized its structure to include the IAU Working Group on Theory and Methods in Astronomy Education. The initial goals of that working group are 1) promoting Astronomy Education Research (AER) by adopting the international collaboration model used by astronomy researchers, 2) fostering international astronomy education and AER capacity through the development of networks, training and shared resources, and 3) improving astronomy education by describing research based approaches to the teaching and learning of astronomy. In support of those efforts, the working group began a collaboration with the Center for Astronomy & Physics Education Research to develop the International Study of Astronomy Reasoning (ISTAR) Database, an online, searchable research tool, intended to catalog, characterize, and provide access to all known astronomy education research production, world-wide. Beginning in the Summer of 2015, a test of ISTAR's functionality began with a survey of a previously uncatalogued set of test objects: U.S.-based doctoral dissertations and masters. This target population was selected for its familiarity to the ISTAR developers, and for its small expected sample size (50-75 objects). First light observations indicated that the sample exceeded 300 dissertation objects. These objects were characterized across multiple variables, including: year of production, document source, type of resource, empirical methodology, context, informal setting type, research construct, type of research subject, scientific content, language, and nation of production. These initial observations provide motivation to extend this project to observe masters levels thesis, which are anticipated to be ten times more numerous as doctoral dissertations, other peer-reviewed contributions, contributions from the larger international community.

  11. Intelligent Cognitive Radio Models for Enhancing Future Radio Astronomy Observations

    Directory of Open Access Journals (Sweden)

    Ayodele Abiola Periola

    2016-01-01

    Full Text Available Radio astronomy organisations desire to optimise the terrestrial radio astronomy observations by mitigating against interference and enhancing angular resolution. Ground telescopes (GTs experience interference from intersatellite links (ISLs. Astronomy source radio signals received by GTs are analysed at the high performance computing (HPC infrastructure. Furthermore, observation limitation conditions prevent GTs from conducting radio astronomy observations all the time, thereby causing low HPC utilisation. This paper proposes mechanisms that protect GTs from ISL interference without permanent prevention of ISL data transmission and enhance angular resolution. The ISL transmits data by taking advantage of similarities in the sequence of observed astronomy sources to increase ISL connection duration. In addition, the paper proposes a mechanism that enhances angular resolution by using reconfigurable earth stations. Furthermore, the paper presents the opportunistic computing scheme (OCS to enhance HPC utilisation. OCS enables the underutilised HPC to be used to train learning algorithms of a cognitive base station. The performances of the three mechanisms are evaluated. Simulations show that the proposed mechanisms protect GTs from ISL interference, enhance angular resolution, and improve HPC utilisation.

    Providing meaningful telescope observing experiences for students who are deeply urban or distantly rural place-bound--or even daylight time-bound--has consistently presented a formidable challenge for astronomy educators. For nearly 2 decades, the Internet has promised unfettered access for large numbers of students to conduct remote telescope…

  13. Observing Exercises in Astronomy: An Opportunity to Incorporate a Multicultural Approach to Astronomy Education

    Science.gov (United States)

    Phelps, R. L.

    2001-05-01

    As part of an Introductory Astronomy course (AS 4), a set of "Night Observing Exercises" have been developed to help students learn about astronomical events and motions, and to help them better understand their place in the Universe. These exercises are specifically intended to help California State University, Sacramento (CSUS) students, who often have evening jobs and family obligations, fit the exercises in around their schedules. This differs from a traditional astronomy lab that requires a student to be on campus during evening hours. The observations (e.g., location of sunset on the horizon, motions of stars throughout the semester) are made at home or at work, and use crude measurement techniques (e.g., angles are measured using the student's outstretched hand), but they nonetheless give the precision needed to demonstrate astronomical concepts. Additionally, the measurements are used, at the end of the semester, to answer specific astronomical questions while incorporating the uncertainties associated with the student's measurements. In this way, therefore, students gain an appreciation of the beauty of the astronomical sky, understand the motions that occur, and get a sense of the importance of uncertainties in scientific measurements. The CSUS student body is also among the most diverse in the Western U.S. A unique aspect of these Night Observing Exercises is the ability to enhance the multicultural component of astronomical teaching. The Inca and the Maya, for example, were maticulous observers of the Sun and Venus, respectively. This paper presents presents a report on techniques that can be used to show students, from cultures typically underrepresented in science, how astronomy is part of their own heritage. This work was supported, in part, by a Pedagogy Enhancement grant from the California State University, Sacramento

  15. Using Observational Journals in an Introductory Astronomy Course

    Sadler, P.

    2000-05-01

    The might of science is in its power to predict. Yet, students rarely are exposed to anything but others' stories concerning how nature behaves. Students do not experience the frustration and elation that discovery brings. For ten years, our introductory astronomy course has used observational journals as a key component in the learning process. Every night, as the planets, stars, and moon dance by, astronomy students use the opportunity to collect and analyze their own data describing heavenly motions. For most, finding the patterns in original data provides an opportunity to fashion and test their own predictive models for the first time in their lives. Such efforts provide an alternative to lecture and laboratory for mastering key scientific concepts and modifying student misconceptions. Students have learned how to represent visual information through a variety of graphs, built and improved their own measurement instruments, and drawn on artistic and writing skills. We will examine the steps required to make observational journals a productive learning activity: careful recordkeeping, classroom discussion, instructor feedback, and reflective writing. I will show examples of how students' work progress through increasing levels of cognitive sophistication that match well with learning theories.

  16. Observers, Publications, and Surveys: Astronomy in the United States in 1849

    Rothenberg, Marc

    1999-01-01

    By the mid-19th century, astronomy in the United States was productive and growing. Information gathered by and at the behest of the Smithsonian Institution shows that the community consisted of approximately 50 individuals, including a significant number of military officers, and a dozen observatories. Americans were deeply involved in astronomical research, and the discipline was entrenched in the college curriculum. What the discipline lacked was an adequate publication vehicle to ensure refereed, rapid dissemination of observations.

  17. Political astronomy: Comet and meteor observations by Muslim historians

    Science.gov (United States)

    Chander Kapoor, Ramesh

    2015-08-01

    Eclipses and unexpected phenomena like comets, meteors, novae and earthquakes were viewed among various cultures as violating the established order of the heavens. They were considered to be ill omens for kings and emperors and were routinely monitored. The present work looks into the texts of history and literature by Muslim historians and chroniclers in West Asia and India that carry stray references to such phenomena. The accounts often relate the apparitions to specific disastrous events or prognosticate revolts, deaths, epidemics, earthquakes all that that took place in later times. Obviously, the occurrences interested the astrologers more. Comet appearances would last for days and weeks but nearly all the writings lack sequential observations. Meteor showers are annual features but the Islamic calendar being lunar would not easily lead one to notice periodic nature of the incidents, let alone sensing a periodicity in comet appearances. These are non-astronomy texts with little scientific content but being from different ages permit us to see how the astronomical perceptions changed over the times. The recorded details and firm chronology, tested against modern back calculations, can provide valuable information on them, keeping in mind the text and the context in which the original reference was made. We also notice a qualitative change in the Indian writings of the 18th century and later where the authors begin to show up with influence of exposure to the European scientific progress.

  18. Global TIE Observatories: Real Time Observational Astronomy Through a Robotic Telescope Network

    Science.gov (United States)

    Clark, G.; Mayo, L. A.

    2001-12-01

    Astronomy in grades K-12 is traditionally taught (if at all) using textbooks and a few simple hands-on activities. Teachers are generally not trained in observational astronomy techniques and are unfamiliar with the most basic astronomical concepts. In addition, most students, by High School graduation, will never have even looked through the eyepiece of a telescope. The problem becomes even more challenging in inner cities, remote rural areas and low socioeconomic communities where educational emphasis on topics in astronomy as well as access to observing facilities is limited or non existent. Access to most optical telescope facilities is limited to monthly observing nights that cater to a small percentage of the general public living near the observatory. Even here, the observing experience is a one-time event detached from the process of scientific enquiry and sustained educational application. Additionally, a number of large, "research grade" observatory facilities are largely unused, partially due to the slow creep of light pollution around the facilities as well as the development of newer, more capable telescopes. Though cutting edge science is often no longer possible at these sights, real research opportunities in astronomy remain numerous for these facilities as educational tools. The possibility now exists to establish a network of research grade telescopes, no longer useful to the professional astronomical community, that can be made accessible through classrooms, after school, and community based programs all across the country through existing IT technologies and applications. These telescopes could provide unparalleled research and educational opportunities for a broad spectrum of students and turns underutilized observatory facilities into valuable, state-of-the-art teaching centers. The NASA sponsored Telescopes In Education project has been wildly successful in engaging the K-12 education community in real-time, hands-on, interactive astronomy

  19. The Universe Observation Center: an educational center devoted to Astronomy in Catalonia

    Science.gov (United States)

    Fernández, D.

    The Universe Observation Center (in Catalan language, Centre d'Observació de l'Univers, COU) is located in close proximity to the Montsec Astronomical Observatory (Observatori Astronòmic del Montsec, OAM), in eastern Catalonia (Spain). Both centers comprise the Montsec Astronomical Park (Parc Astronòmic Montsec, PAM), managed by the Consorci del Montsec. Montsec Mountain remains the finest location for astronomical observation in Catalonia, as demonstrated by a site-testing campaign conducted by the Astronomy and Meteorology Department of the University of Barcelona. The COU consists of a Central Building (including a permanent exhibition and three classrooms possessing broadband Internet access), the Telescope Park (two astronomical domes equipped with medium-size telescopes, a coelostat for solar observation, and a portable telescope park), the Eye of Montsec (a digital planetarium and, at the same time, an extremely innovative platform for sky observation) and the Garden of the Universe (a tour of the land surrounding the COU, visiting several areas within it). The COU will offer to the Spanish academic community a host of fascinating and unique activities in the fields of astronomy and geology. The Center is open not only to students (from primary school through university), but also to amateur astronomers, people interested in science and the general public.

  20. Astronomy at the frontiers of science

    CERN Document Server

    2011-01-01

    Astronomy is by nature an interdisciplinary activity: it involves mathematics, physics, chemistry and biology. Astronomers use (and often develop) the latest technology, the fastest computers and the most refined software.  In this book twenty-two leading scientists from nine countries talk about how astronomy interacts with these other sciences. They describe modern instruments used in astronomy and the relations between astronomy and technology, industry, politics and philosophy. They also discuss what it means to be an astronomer, the history of astronomy, and the place of astronomy in society today.   The book contains twenty chapters grouped in four parts: ASTRONOMY AND PHYSICS discusses the place of astronomy among various branches of (mostly high-energy) physics. ASTRONOMY IN SOCIETY describes not only the historical context of astronomy, but issues facing astronomers today, including funding, planning, worldwide collaboration and links with industry. THE TOOLS OF OBSERVATION AND THE PROFESSION OF AS...

    Essick, Reed; LIGO-Virgo Collaboration

    2017-01-01

    I present an overview of the types of low latency searches operated by the LIGO-Virgo collaboration, focusing on the products produced by each and how they tie into the broader astronomical community. This includes both automated and manual follow-up to characterize the source localization as well as statements about the data quality surrounding the candidate. In broad strokes, I'll also describe the internal and external communication mechanisms put in place to announce candidates and report follow-up activities, with particular emphasis placed on how GW and EM data are mutually beneficial. Time permitting, I will also describe some consequences of observed diurnal cycles governing when the LIGO detectors are likely to record data and studies comparing localizations from different algorithms.

  2. Early Astronomy

    Science.gov (United States)

    Thurston, Hugh

    The earliest investigations that can be called scientific are concerned with the sky: they are the beginnings of astronomy. Many early civilizations produced astronomical texts, and several cultures that left no written records left monuments and artifacts-ranging from rock paintings to Stonehenge-that show a clear interest in astronomy. Civilizations in China, Mesopotamia, India and Greece had highly developed astronomies, and the astronomy of the Mayas was by no means negligible. Greek astronomy, as developed by the medieval Arab philosophers, evolved into the astronomy of Copernicus. This displaced the earth from the central stationary position that almost all earlier astronomies had assumed. Soon thereafter, in the first decades of the seventeenth century, Kepler found the true shape of the planetary orbits and Galileo introduced the telescope for astronomical observations.

  3. Compendium of Practical Astronomy

    Science.gov (United States)

    Roth, Günter D.; Augensen, H. J.; Heintz, W. D.

    The Compendium of Practical Astronomy is a revised and enlarged English version of the fourth edition of G. Roth's famous handbook for stargazers. In three volumes 28 carefully edited articles aimed especially at amateur astronomers and students and teachers of astronomy in high schools and colleges cover the length and breadth of practical astronomy. Volume 1 contains information on modern instrumentation and reduction techniques, including spherical astronomy, error estimations, telescope mountings, astrophotography, and more. Volume 2 covers the planetary system, with contributions on artificial satellites, comets, the polar aurorae, and the effects of the atmophere on observational data. Volume 3 is devoted to stellar objects, variable stars and binary stars in particular, the Milky Way and Galaxies. An introduction to the astronomical literature and a comprehensive chapter on astronomy education and instructional aids make the Compendium a useful complement to any college library.

    Science.gov (United States)

    Ribas, Salvador J.

    2011-06-01

    The Universe Observing Center is one of the parts of the Parc Astronòmic Montsec (PAM). PAM is an initiative of the Catalan government, through the Consorci del Montsec (Montsec Consortium), to take advantage of the capabilities and potential of the Montsec region to develop scientific research, training and outreach activities, particularly in the field of Astronomy. The choice of the Montsec mountains to install the PAM was motivated by the magnificent conditions for observing the sky at night; the sky above Montsec is the best (natural sky free of light pollution) in Catalonia for astronomical observations. The PAM has two main parts: the Observatori Astronòmic del Montsec (OAdM) and the Universe Observing Center (COU). The OAdM is a professional observatory with an 80-cm catadioptric telescope (Joan Oró Telescope). This telescope is a robotic telescope that can be controlled from anywhere in the world via the Internet. The COU is a large multipurpose center which is intended to become an educational benchmark for teaching and communicate astronomy and other sciences in Catalonia. The management of the COU has three main goals: 1) Teach primary and secondary school students in our Educational Training Camp. 2) Teach university students housing the practical astronomy lectures of the universities. 3) Communicate astronomy to the general public. The COU comprises special areas for these purposes: the Telescopes Park with more than 20 telescopes, a coelostat for solar observations and two dome containing full-automated telescopes. The most special equipment is ``The Eye of Montsec'', with its 12m dome containing a multimedia digital planetarium and a platform for direct observation of the sky and the environment. During 2009 we expect around 10000 visitors in Montsec area to enjoy science with Montsec dark skies and an special natural environment.

    The astronomy and space physics investigations conducted in the Skylab program include over 20 experiments in four categories to explore space phenomena that cannot be observed from earth. The categories of space research are as follows: (1) phenomena within the solar system, such as the effect of solar energy on Earth's atmosphere, the composition of interplanetary space, the possibility of an inner planet, and the X-ray radiation from Jupiter, (2) analysis of energetic particles such as cosmic rays and neutrons in the near-earth space, (3) stellar and galactic astronomy, and (4) self-induced environment surrounding the Skylab spacecraft.

    The Neptune flyby in 1989 added a new planet to the known number of magnetized planets generating nonthermal radio emissions. We review the Neptunian radio emission morphology as observed by the planetary radio astronomy experiment on board Voyager 2 during a few weeks before and after closest approach. We present the characteristics of the two observed recurrent main components of the Neptunian kilometric radiation, i.e., the 'smooth' and the 'bursty' emissions, and we describe the many specific features of the radio spectrum during closest approach.

  9. Planck's High Temperature Catastrophe in Observational Astronomy:- (NASA proves Planck wrong)

    Science.gov (United States)

    Gall, Clarence A.

    2009-03-01

    Planck's black body radiation law ( IP=c1 λ^51e^c2λT -1) predicts that a hotter body (higher T) should always emit more intensely than a colder body (lower T) throughout the entire EMR spectrum. However, space age infrared astronomy contradicts this prediction! It is now known that as observation moves from the visible to the near-, mid- and far infrared; increasingly cold celestial objects come into view while hotter ones fade and disappear (http://coolcosmos.ipac.caltech.edu/cosmicclassroom/irtutori al/irregions.html). Were Planck's law valid, the hottest stars would never disappear; and colder objects would not be detected. This can only be described as a high temperature catastrophe (BAPS, April Meeting 2008, H12.3, St Louis, MO) for Planck's law! On the other hand, Gall's black body radiation law ( IG=σT^6b^2λe^-λTb) (http://sites.google.com/site/purefieldphysics) predicts that as wavelength increases, there is a crossover point above which a colder object will emit more intensely than a hotter one. Hence colder objects will appear and hotter ones will eventually disappear from view. The crossover point for black bodies at 6000K and 100K is 12.066 microns. These calculations with Gall's law are in overall agreement with observational infrared astronomy.

  10. Observations of an indigenous Hawaiian planetarium operator: Astronomy content knowledge of Hawaiian school children

    Science.gov (United States)

    Dye, Ahia G.; Ha`o, Celeste; Slater, Timothy F.; Slater, Stephanie J.

    2015-08-01

    Not so long ago, astronomers visiting schools in Hawaii tried to build awareness among school children and teachers about how stars move across the sky, the nature of planets orbiting our sun, and the physical processes governing stars and galaxies. While these efforts were undertaken with all good intentions, they were often based on our collective understanding of how Mainland children come to know astronomy topics, and with a Western worldview. Research observations of Hawaiian elementary school children indicate that Hawaiian children understand far more about the skies than could have been predicted from the behavior of Mainland children, or from the body of literature on children’s understanding of astronomy. Analysis of elementary students’ responses to a kumu’s, or teacher’s questions relating to the celestial sphere indicate that these students posses a deep knowledge of the night sky and celestial motions. This knowledge base is fluent across two cultural systems of constellations, and is predictive. In an era of curriculum development based upon learning progressions, it appears that Native Hawaiian students possess unexpected knowledge that is well poised to interfere with conventional educational and public outreach approaches if not taken into account. Further, these findings suggest that further inquiry must be made into the astronomical thinking of minority populations prior to the unilateral implementation of national science education standards.

    2003-01-01

    Observations of the 1(10)-1(01) 556.936 GHz transition of ortho-water with the Submillimeter Wave Astronomy Satellite (SWAS) have revealed the presence of widespread emission and absorption by water vapor around the strong submillimeter continuum source Sagittarius B2. An incompletely-sampled spectral line map of a region of size 26 x 19 arcmin around Sgr B2 reveals three noteworthy features. First, absorption by foreground water vapor is detectable at local standard-of-rest (LSR) velocities in the range -100 to 0 km/s at almost every observed position. Second, spatially-extended emission by water is detectable at LSR velocities in the range 80 to 120 km/s at almost every observed position. This emission is attributable to the 180-pc molecular ring identified from previous observations of CO. The typical peak antenna temperature of 0.075 K for this component implies a typical water abundance of 1.2E-6 to 8E-6 relative to H2. Third, strong absorption by water is observed within 5 arcmin of Sgr B2 at LSR veloci...

  12. Statistics in astronomy

    CERN Document Server

    Feigelson, Eric D

    2009-01-01

    Perhaps more than other physical sciences, astronomy is frequently statistical in nature. The objects under study are inaccessible to direct manipulation in the laboratory, so the astronomer is restricted to observing a few external characteristics and inferring underlying properties and physics. Astronomy played a profound role in the historical development of statistics from the ancient Greeks through the 19th century. But the fields drifted apart in the 20th century as astronomy turned towards astrophysics and statistics towards human affairs. Today we see a resurgence in astrostatistical activity with the proliferation of survey mega-datasets and the need to link complicated data to nonlinear astrophysical models. Several contemporary astrostatistical challenges are outlined: heteroscedastic measurement errors, censoring and truncation in multivariate databases; time series analysis of variable objects including dynamical models of extrasolar planetary systems; treatments of faint sources and other Poisso...

    2006-01-01

    On 4 July 2005 at 5:52 UT the Deep Impact mission successfully completed its goal to hit the nucleus of 9P/Tempel 1 with an impactor, forming a crater on the nucleus and ejecting material into the coma of the comet. NASA's Submillimeter Wave Astronomy Satellite (SWAS) observed the 1(10)-1(01) ortho-water ground-state rotational transition in comet 9P/Tempel 1 before, during, and after the impact. No excess emission from the impact was detected by SWAS and we derive an upper limit of 1.8e7 kg on the water ice evaporated by the impact. However, the water production rate of the comet showed large natural variations of more than a factor of three during the weeks before and after the impact. Episodes of increased activity with Q(H2O)~1e28 molecule/s alternated with periods with low outgassing (Q(H2O)<~5e27 molecule/s). We estimate that 9P/Tempel 1 vaporized a total of N~4.5e34 water molecules (~1.3e9 kg) during June-September 2005. Our observations indicate that only a small fraction of the nucleus of Tempel 1...

    Bring telescopes to where the people are! Music and Astronomy Under the Stars is a three-year NASA-funded astronomy outreach program at community parks during and after music concerts and outdoor family events—such as a Halloween Stars-Spooky Garden Walk. While there have been many astronomy outreach activities and telescope observations at city sidewalks and parks, this program targets a completely different audience: music lovers who are attending summer concerts held in community parks. These music lovers who may never have visited a science museum, planetarium, or star party are exposed to telescope observations and astronomy information with no additional travel costs. Music and Astronomy Under the Stars increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. This program includes solar observing before the concerts, telescope observations including a live image projection system, an astronomical video presentation, and astronomy banners/posters. Approximately 500-16,000 people attended each event and 25% to 50% of the people at each event participated in the astronomy program. This program also reached underrepresented and underserved groups (women, minorities, older adults). The target audience (Nassau and Suffolk Counties, New York) is 2,900,000 people, which is larger than combined population of Atlanta, Boston, Denver, Minneapolis, and San Francisco. Although eleven events were planned in 2009, two were canceled due to rain and our largest event, the NY Philharmonic in the Park (attended by 67,000 people in 2008), was cancelled for financial reasons. Our largest event in 2009 was the Tanglewood Music Festival, Lenox MA, attended by 16,000 people where over 5000 people participated in astronomy activities. The Amateur Observers' Society of New York assisted with the NY concerts and the Springfield STARS astronomy club assisted at Tanglewood. In 2009 over 15,000 people participated in astronomy

    Horvath, Thomas J.; Cagle, Melinda F.; Grinstead, Jay H.; Gibson, David M.

    Flight measurement is a critical phase in development, validation and certification processes of technologies destined for future civilian and military operational capabilities. This paper focuses on several recent NASA-sponsored remote observations that have provided unique engineering and scientific insights of reentry vehicle flight phenomenology and performance that could not necessarily be obtained with more traditional instrumentation methods such as onboard discrete surface sensors. The missions highlighted include multiple spatially-resolved infrared observations of the NASA Space Shuttle Orbiter during hypersonic reentry from 2009 to 2011, and emission spectroscopy of comparatively small-sized sample return capsules returning from exploration missions. Emphasis has been placed upon identifying the challenges associated with these remote sensing missions with focus on end-to-end aspects that include the initial science objective, selection of the appropriate imaging platform and instrumentation suite, target flight path analysis and acquisition strategy, pre-mission simulations to optimize sensor configuration, logistics and communications during the actual observation. Explored are collaborative opportunities and technology investments required to develop a next-generation quantitative imaging system (i.e., an intelligent sensor and platform) with greater capability, which could more affordably support cross cutting civilian and military flight test needs.

    2003-12-01

    As part of the education and public outreach efforts of the NASA JPL Navigator, SIRTF Mission and the Astronomical Society of the Pacific, astronomy educators affiliated with the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona are conducting a series of two- and three-day teaching excellence workshops for college faculty. These workshops are being held in conjunction with professional society meetings, such as the American Astronomical Society and the American Association of Physics Teachers, and through the infrastructure of the National Science Foundation's Summer Chautauqua Workshop program. This three-day, interactive teaching excellence workshop focuses on dilemmas astronomy teachers face and develop practical solutions for the troubling issues in curriculum, instruction, and assessment. After reviewing the latest research about how students learn, participants define and set measurable student learning goals and objectives for students in their astronomy courses and construct effective course syllabi reflecting the ASTRO 101 goals publicized by the AAS. To improve instruction, participants learn how to create productive learning environments by using interactive lectures, peer instruction, engaging demonstrations, collaborative groups, tutorials, computer-based laboratories, and observational projects. Participants also learn how to write more effective multiple-choice tests and implement authentic assessment strategies including portfolio assessment, performance tasks, and concept maps. Texts provided at the workshop are: (i) Learner-Centered Astronomy Teaching, Slater and Adams, Prentice Hall, 2002; (ii) Great Ideas for Teaching Astronomy, Pompea, Brooks Cole, 2000; and (iii) Lecture-Tutorials for Introductory Astronomy, Adams, Prather, & Slater, Prentice Hall, 2002.

    Chen, James L

    2017-01-01

    This book is for the aging amateur astronomy population, including newcomers to astronomy in their retirement and hobbyists who loved peering through a telescope as a child. Whether a novice or an experienced observer, the practice of astronomy differs over the years. This guide will extend the enjoyment of astronomy well into the Golden Years by addressing topics such as eye and overall health issues, recommendations on telescope equipment, and astronomy-related social activities especially suited for seniors. Many Baby-Boomers reaching retirement age are seeking new activities, and amateur astronomy is a perfect fit as a leisure time activity. Established backyard astronomers who began their love of astronomy in their youth , meanwhile, may face many physical and mental challenges in continuing their lifelong hobby as they age beyond their 55th birthdays. That perfect telescope purchased when they were thirty years old now suddenly at sixty years old feels like an immovable object in the living room. The 20...

  2. Laboratory Experiments in Physics for Modern Astronomy With Comprehensive Development of the Physical Principles

    CERN Document Server

    Golden, Leslie

    2013-01-01

    This book presents experiments which will teach physics relevant to astronomy. The astronomer, as instructor, frequently faces this need when his college or university has no astronomy department and any astronomy course is taught in the physics department. The physicist, as instructor, will find this intellectually appealing when faced with teaching an introductory astronomy course. From these experiments, the student will acquire important analytical tools, learn physics appropriate to astronomy, and experience instrument calibration and the direct gathering and analysis of data. Experiments that can be performed in one laboratory session as well as semester-long observation projects are included. This textbook is aimed at undergraduate astronomy students.

    2008-11-01

    Bring telescope to where the people are! Music and Astronomy Under the Stars is a public astronomy outreach program at community parks during and after free summer music concerts and outdoor movie nights. This project also includes daytime activities because there are some afternoon concerts and daylight children's concerts, and observations using remotely operated telescopes in cloudy weather. While there have been many astronomy outreach activities and telescope observations at city sidewalks and parks, this program targets a completely different audience---music lovers who are attending free summer concerts held in community parks. The music lovers who may never have visited a science museum, planetarium, or star party will be exposed to telescope observations and astronomy information with no additional travel costs. This program will permit the entire community to participate in telescope observations and view astronomical video information to enhance the public appreciation of astronomy. This program will also reach underrepresented and underserved groups (women, minorities, older adults). The population base for the initial target audience (Nassau and Suffolk Counties, New York) is 2,500,000. My partners are the Amateur Observers' Society of New York (AOS) and the Towns of Oyster Bay, Hempstead, North Hempstead, and Huntington. Music and Astronomy Under the Stars is program that should continue beyond the International Year of Astronomy 2009 (IYA2009) and can be expanded into a national program.

    Saeidi, Rahim; Astudillo, Ramon Fernandez; Kolossa, Dorothea

    2016-07-01

    Linear discriminant analysis (LDA) is a powerful technique in pattern recognition to reduce the dimensionality of data vectors. It maximizes discriminability by retaining only those directions that minimize the ratio of within-class and between-class variance. In this paper, using the same principles as for conventional LDA, we propose to employ uncertainties of the noisy or distorted input data in order to estimate maximally discriminant directions. We demonstrate the efficiency of the proposed uncertain LDA on two applications using state-of-the-art techniques. First, we experiment with an automatic speech recognition task, in which the uncertainty of observations is imposed by real-world additive noise. Next, we examine a full-scale speaker recognition system, considering the utterance duration as the source of uncertainty in authenticating a speaker. The experimental results show that when employing an appropriate uncertainty estimation algorithm, uncertain LDA outperforms its conventional LDA counterpart.

    2009-01-01

    The recent years have seen breathtaking progress in technology, especially in the receiver and digital technologies relevant for radio astronomy, which has at the same time advanced to shorter wavelengths. This is the updated and completely revised 5th edition of the most used introductory text in radio astronomy. It presents a unified treatment of the entire field from centimeter to sub-millimeter wavelengths. Topics covered include instruments, sensitivity considerations, observational methods and interpretations of the data recorded with both single dishes and interferometers. This text is useful to both students and experienced practicing astronomers. Besides making major updates and additions throughout the book, the authors have re-organized a number of chapters to more clearly separate basic theory from rapidly evolving practical aspects. Further, problem sets have been added at the end of each chapter.

    Astronomy has played a major part in the development of civilisations, not only through conceptual developments, but most importantly through the very practical gains obtained through the observation of Sun, Moon planets and stars. Space sciences, including astronomy, have also played a major role in the development of modern societies, as engine for most subsequent space technology developments. Present trends tend to decrease the role of science in space development. This trend should be reversed to give modern "societies" their independence in space related matters that permeate the lives of all inhabitants of the Earth.

    Now in its sixth edition this successful undergraduate textbook gives a well-balanced and comprehensive introduction to the topics of classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. The chapters on galactic and extragalactic astronomy as well as cosmology were extensively modernized in the previous edition. In this new edition they have been further revised to include more recent results. The long chapter on the solar system has been split into two parts: the first one deals with the general properties, and the other one describes individual objects. A new chapter on exoplanets has been added to the end of the book next to the chapter on astrobiology. In response to the fact that astronomy has evolved enormously over the last few years, only a few chapters of this book have been left unmodified. Long considered a standard text for physical science maj...

    2015-07-01

    Cultural Astronomy is the reflection of sky events in various fields of nations' culture. In foreign literature this field is also called "Astronomy in Culture" or "Astronomy and Culture". Cultural astronomy is the set of interdisciplinary fields studying the astronomical systems of current or ancient societies and cultures. It is manifested in Religion, Mythology, Folklore, Poetry, Art, Linguistics and other fields. In recent years, considerable attention has been paid to this sphere, particularly international organizations were established, conferences are held and journals are published. Armenia is also rich in cultural astronomy. The present paper focuses on Armenian archaeoastronomy and cultural astronomy, including many creations related to astronomical knowledge; calendars, rock art, mythology, etc. On the other hand, this subject is rather poorly developed in Armenia; there are only individual studies on various related issues (especially many studies related to Anania Shirakatsi) but not coordinated actions to manage this important field of investigation.

    2009-01-01

    With amateurs, students, and teachers of astronomy in high schools and colleges particularly in mind, the Handbook of Practical Astronomy is an essential source to demonstrate trends and variety of astronomical observations. The book presents the substance of celestial bodies for the amateur observer: the planets, the stars, and the galaxies. The sun is the local link to the other stars, the nexus of cosmic evolution. The solar system is made up by the sun and all the celestial bodies orbit it. This system is of special interest for the observing amateur. The Handbook of Practial Astronomy spans astronomy, education and computing. Like many other fields of science, astronomy has become digitized and data rich in recent years. Besides the references at the end of each chapter, there are the notes in the margins with astronomical news and observing highlights on the web.

    2000-01-01

    We have used the Submillimeter Wave Astronomy Satellite to map the ground-state 1_{10}-1_{01} transition of ortho-water at 557 GHz in the Orion molecular cloud. Water emission was detected in Orion over an angular extent of about 20 arcmin, or nearly 3 pc. The water emission is relatively weak, with line widths (3-6 km s^{-1}) and V_{LSR} velocities (9-11 km s^{-1}) consistent with an origin in the cold gas of the molecular ridge. We find that the ortho-water abundance relative to H_2 in the extended gas in Orion varies between 1 and 8x10^{-8}, with an average of 3x10^{-8}. The absence of detectable narrow-line ortho-H_2^{18}O emission is used to set a 3-sigma upper limit on the relative ortho-water abundance of 7x10^{-8}.

    Abstract What's Up video podcasts: connecting "astronomy for everyone" monthly astronomical views with related NASA missions, science, images and handson education. Background: What's Up Podcasts are 2 minute video podcasts available through RSS feed, You tube, and NASA websites every month. They feature an astronomy related viewing target in the sky each month, targets visible to everyone, from city or country, just by looking up! No telescope is required to view these objects. Summary: Expand and broaden the scope of the existing "What's Up" public astronomy themed video podcasts. NASA builds partnerships and linkages between Science, Technology, Engineering and Mathematics formal and informal education providers. What's Up podcasts provides a link between astronomical views and events, or "what's up in the night sky this month" with current NASA missions, mission milestones and events, space telescope images or press releases. These podcasts, plus supporting star charts, hands-on activities, standards-based educational lessons and mission links will be used by museums, planetariums, astronomy clubs, civic and youth groups, as well as by classrooms and the general public. They can be translated to other languages, too. Providing the podcasts in high definition, through the NASA websites, You Tube, iTunes and other web video sharing sites reaches wide audiences of all ages. Third Saturn Observation Night - May 18, 2008 Centered on Saturn Opposition, when the Sun and Saturn are on opposite sides of the Earth, all IYA participants - in all countries around the world - will be encouraged to take their telescopes out and share the planet Saturn with their communities. NASA's International Saturn Observation Campaign network of astronomy enthusiasts has now conducted a Saturn Observation Night event for the past 2 years, and it succeeds by building an international community all sharing Saturn. This celebration has been successfully conducted in hundreds of locations

    2011-01-01

    Currently astronomy learning is heavily geared towards visual aids; however, roughly 10 million people in North America are sight impaired. Every student should have access to meaningful astronomy curriculum; an understanding of astronomy is an expectation of national and state science learning requirements. Over the last ten years, Noreen Grice has developed Braille and large print astronomy text books aimed at sight impaired learners. We build upon Grice's written work and present here a five day lesson plan that integrates 2D reading with 3D activities. Through this curriculum, students develop an intuitive understanding of astronomical distance, size, composition and lifetimes. We present five distinct lesson modules that can be taught individually or in a sequential form: the planets, our sun, stars, stellar evolution and galaxies. We have tested these modules on sight impaired students and report the results here. Overall, we find the work presented here lends itself equally well to a week long science camp geared toward middle school sight impaired taught by astronomers or as supplemental material integrated into a regular classroom science curriculum. This work was made possible by a 2007 Simple Effective Education and Dissemination (SEED) Grant For Astronomy Researchers, Astronomical Society of the Pacific through funds provided by the Planck Mission, Jet Propulsion Laboratory, California Institute of Technology.

  17. Organizations and Strategies in Astronomy, Volume 5

    Science.gov (United States)

    Heck, André

    2004-10-01

    This book is the fifth volume under the title Organizations and Strategies in Astronomy (OSA). These OSA Books are intended to cover a large range of fields and themes. In practice, one could say that all aspects of astronomy-related life and environment are considered in the spirit of sharing specific expertise and lessons learned. This book offers a unique collection of chapters dealing with socio-dynamical aspects of the astronomy (and related space sciences) community: characteristics of organizations, strategies for development, operational techniques, observing practicalities, educational policies, public outreach, publication studies, research communication, evaluation procedures, research indicators, national specificities, contemporary history, and so on. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy while providing specific detailed information and sometimes enlightening ‘lessons learned’ sections. The book concludes with an updated bibliography of publications related to socio-astronomy and to the interactions of the astronomy community with the society at large. This book will be most usefully read by researchers, teachers, editors, publishers, librarians, sociologists of science, research planners and strategists, project managers, public-relations officers, plus those in charge of astronomy-related organizations, as well as by students aiming at a career in astronomy or related space science. The book includes a CD-ROM containing the visionary and fascinating work of L. Pešek as a space artist. "More than anything else, Organizations and Strategies in Astronomy is about change, recording where we've been and how we have evolved, and extrapolating to where we will be in the coming decades."

    Mickaelian, A. M.

    2016-09-01

    Two major characteristics of modern astronomy are multiwavelength (MW) studies (fromγ-ray to radio) and big data (data acquisition, storage and analysis). Present astronomical databases and archives contain billions of objects observed at various wavelengths, both galactic and extragalactic, and the vast amount of data on them allows new studies and discoveries. Astronomers deal with big numbers. Surveys are the main source for discovery of astronomical objects and accumulation of observational data for further analysis, interpretation, and achieving scientific results. We review the main characteristics of astronomical surveys, compare photographic and digital eras of astronomical studies (including the development of wide-field observations), describe the present state of MW surveys, and discuss the Big Data in astronomy and related topics of Virtual Observatories and Computational Astrophysics. The review includes many numbers and data that can be compared to have a possibly overall understanding on the Universe, cosmic numbers and their relationship to modern computational facilities.

    We present the time variability characteristics of Cygnus X-1 in its two spectral states. The observations were carried out using the Pointed Proportional Counters (PPC) on-board the Indian X-ray Astronomy Experiment (IXAE). The details of the instrument characteristics, the observation strategy, and the background modeling methods are described. In the soft state of Cyg X-1, we confirm the general trend of the Power Density Spectrum (PDS) obtained using the Proportional Counter Array (PCA) on-board the RXTE satellite. The hard state of the source just prior to the spectral transition was not observed by the PCA and we present the PDS obtained in this state. We find that the low frequency end of the PDS is flatter than that observed during the spectral transition. Additionally, we find that there is one more component in the low frequency end of the PDS, which is independent of the spectral state of the source. The time variability is also examined by taking the statistics of the occurrence of shots and it is...

    The 13th Gravitational Wave Data Analysis Workshop took place in San Juan, Puerto Rico on the 19-22 January 2009. This annual event has become the established venue for presenting and discussing new results and techniques in this crucial subfield of gravitational wave astronomy. A major attraction of the event is that scientists working with all possible instruments gather to discuss their projects and report on the status of their observations. The Center for Gravitational Wave Astronomy at the University of Texas at Brownsville, USA (a National Aeronautics and Space Administration University Research Center and a National Science Foundation Center for Research Excellence in Science and Technology) jointly with the National Astronomy and Ionosphere Center (which operates the Arecibo Observatory) were the proud sponsors of the gathering this time. As in previous years, GWDAW13 was well attended by more than 100 participants from over 10 countries worldwide As this issue is going to press GEO, LIGO and VIRGO are undergoing new scientific runs of their instruments with the LIGO detectors holding the promise of increasing their operational sensitivity twofold as compared with the observations finished a couple of years ago. This new cycle of observations is a major milestone compared to the previous observations which have been accomplished. Gravitational waves have not been observed yet, but the instrumental sensitivity achieved has started producing relevant astrophysical results. In particular, very recently (Nature, 20 August 2009) a letter from the LIGO Scientific Collaboration http://www.ligo.org and the VIRGO Collaboration http://www.virgo.infn.it has set the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where current gravitational wave detectors can observe. These results have put new constraints on the physical characteristics of the early universe. The proximity

    In developing nations such as Mexico, basic science education has scarcely improved. There are multiple reasons for this problem; they include poor teacher training and curricula that are not challenging for students. I shall suggest ways in which astronomy can be used to improve basic education, it is so attractive that it can be employed to teach how to read and write, learn a second language, mathematics, physics, as well as geography. If third world nations do not teach science in an adequate way, they will be in serious problems when they will try to achieve a better standard of living for their population. I shall also address informal education, it is by this means that most adults learn and keep up to date with subjects that are not their specialty. If we provide good outreach programs in developing nations we can aid adult training; astronomy is ideal since it is particularly multidisciplinary. In particular radio and television programs are useful for popularization since they reach such wide audiences.

  2. Europe's Astronomy Teachers Meet at ESO

    1994-12-01

    European Association for Astronomy Education Formed A joint EU/ESO Workshop (1) on the Teaching of Astronomy in Europe was held at the ESO Headquarters from November 25-30, 1994, under the auspices of the 1994 European Week for Scientific Culture. More than 100 teachers from secondary schools in 17 European countries participated together with representatives of national ministries and local authorities, as well as professional astronomers. This meeting was the first of its kind ever held and was very successful. As a most visible and immediate outcome, the participants agreed to form the "European Association for Astronomy Education (EAAE)", uniting astronomy educators all over Europe into one network. A provisional Executive Committee of the EAAE was elected which will work towards the organisation of a constitutional conference within the next year. The participants unanimously adopted a "Declaration on the Teaching of Astronomy in Europe", specifying the overall aims and initial actions needed to achieve them. Astronomy: Science, Technology and Culture At the beginning of the Workshop the participants listened to lectures by several specialists about some of the most active fields of astronomy. The scientific sessions included topics as diverse as minor bodies in the solar system, nucleosynthesis, interstellar chemistry and cosmology. Then followed overviews of various recent advances in astronomical technology, some of which are already having direct impact on highly specialized sectors of European industry. They included the advanced use of computers in astronomy, for instance within image processing and data archiving, as well as a demonstration of remote observing. Discussing the cultural aspects, Nigel Calder (UK) and Hubert Reeves (France) emphasized the important role of astronomy in modern society, in particular its continuing influence on our perceptions of mankind's unique location in time and space.

    2014-01-01

    Binoculars have, for many, long been regarded as an “entry level” observational tool, and relatively few have used them as a serious observing instrument. This is changing! Many people appreciate the relative comfort of two-eyed observing, but those who use binoculars come to realize that they offer more than comfort. The view of the stars is more aesthetically pleasing and therefore binocular observers tend to observe more frequently and for longer periods. Binocular Astronomy, 2nd Edition, extends its coverage of small and medium binoculars to large and giant (i.e., up to 300mm aperture) binoculars and also binoviewers, which brings the work into the realm of serious observing instruments. Additionally, it goes far deeper into the varying optical characteristics of binoculars, giving newcomers and advanced astronomers the information needed to make informed choices on purchasing a pair. It also covers relevant aspects of the physiology of binocular (as in “both eyes”) observation. The first edition ...

  6. Estimate of the Chinese astronomy development through the descriptions of nova observations

    Science.gov (United States)

    Nickiforov, Mihael G.

    More than a hundred descriptions of guest stars observations made by Chinese, Korean and Japanese astronomers from 6th till 17th centuries are examined in this work. The comparison of the distribution of star outbursts on galactic latitudes from the Chinese sources with the modern data casts doubt on the reliability of the ancient observations. The text analysis shows that the technique of the descriptions of the places of outbursts of new stars does not change from the first ancient observations till the 16th century. This is a sign of a lack of precise instrumental measurements until the arrival of the Jesuits, in 16th century, and of a lack of Chinese star catalog in the medieval China.

    2001-12-01

    This book results from presentations and discussions by a group of astronomers and historians during a three-day workshop held at Tihany (Hungary), on 13-15 August 1999. This meeting - the second forum dedicated to the rise of observational astrophysics in the nineteenth and early twentieth century - coincided with the centenary of Hungary's national observatory. The basic principle of this series of meetings is to reflect on the work and personality of a single individual or of a group of persons, at the same time avoiding the really dominant figures that typify the age. The series focuses on key people who epitomize a way of thinking and working, that has in turn formed many of the ideas by which we do astrophysical research today. Hence the evocation of the scientific spirit of the era under consideration is attempted. Such a leading key person undoubtedly was Miklós Konkoly Thege. A superb instrumentalist and observer, Konkoly became the founding father of Hungarian astronomy through the establishment of his private observatory that later became the Royal Hungarian Ogyalla Observatory, the precursor of the modern Konkoly Observatory. The workshop was organized at the occasion of the centennial anniversary of Konkoly Observatory. The book outlines five major themes. The first part describes the birth of observational astrophysics in Hungary and focuses on historical aspects of 19th-century Hungarian astronomy from three different viewpoints: the historical narrative based on historical facts, the perspective as seen by an expert in historical instrumentation, and a discussion of the socio-political consequences of nineteenth-century developments for our present times. The second part analyses the birth of observational astrophysics in countries with which Konkoly and his collaborators had close contacts: Japan, South Africa and France. The third part of the book discusses the establishment of the discipline of photometry worldwide. An important aspect of 19th

  10. Characterizing Interference in Radio Astronomy Observations through Active and Unsupervised Learning

    Doran, G.

    2013-01-01

    In the process of observing signals from astronomical sources, radio astronomers must mitigate the effects of manmade radio sources such as cell phones, satellites, aircraft, and observatory equipment. Radio frequency interference (RFI) often occurs as short bursts (< 1 ms) across a broad range of frequencies, and can be confused with signals from sources of interest such as pulsars. With ever-increasing volumes of data being produced by observatories, automated strategies are required to detect, classify, and characterize these short "transient" RFI events. We investigate an active learning approach in which an astronomer labels events that are most confusing to a classifier, minimizing the human effort required for classification. We also explore the use of unsupervised clustering techniques, which automatically group events into classes without user input. We apply these techniques to data from the Parkes Multibeam Pulsar Survey to characterize several million detected RFI events from over a thousand hours of observation.

    From the new Zwicky Transient Facility (ZTF), an NSF funded project based at Caltech, comes a new initiative for undergraduate research known as the Summer Undergraduate Astronomy Institute. The Institute brings together 15-20 students from across the world for an immersive experience in astronomy techniques before they begin their summer research projects. The students are primarly based at Caltech in their SURF program but also includes a large cohort of students enrolled in research internships at Pomona College in nearby Claremont CA. The program is intended to introduce students to research techniques in astronomy, laboratory and computational technologies, and to observational astronomy. Since many of the students are previously computer science or physics majors with little astronomy experience, this immersive experience has been extremely helpful for enabling students to learn about the terminologies, techniques and technologies of astronomy. The field trips to the Mount Wilson and Palomar telescopes deepen their knowledge and excitement about astronomy. Lectures about astronomical research from Caltech staff scientists and graduate students also provide context for the student research. Perhaps more importantly, the creation of a cohort of like-minded students, and the chance to reflect about careers in astronomy and research, give these students opportunities to consider themselves as future research scientists and help them immensely as they move forward in their careers. We discuss some of the social and intercultural aspects of the experience as well, as our cohorts typically include international students from many countries and several students from under-represented groups in science.

    2015-08-01

    In its strategic planning for the "Astronomy for Development Project," the International Astronomical Union (IAU) has ecognized, among other important missions, the role of astronomy in understanding the far-reaching possibilities for promoting global tolerance and citizenship. Furthermore, astronomy is deemed inspirational for careers in science and technology. The "Pilot Astronomy Outreach Project in Bangladesh"--the first of its kind in the country--aspires to fulfill these missions. As Bangladesh lacks resources to promote astronomy education in universities and schools, the role of disseminating astronomy education to the greater community falls on citizen science organizations. One such group, Anushandhitshu Chokro (AChokro) Science Organization, has been carrying out a successful public outreach program since 1975. Among its documented public events, AChokro organized a total solar eclipse campaign in Bangladesh in 2009, at which 15,000 people were assembled in a single open venue for the eclipse observation. The organization has actively pursued astronomy outreach to dispel public misconceptions about astronomical phenomena and to promote science. AChokro is currently working to build an observatory and Science Outreach Center around a recently-acquired 14-inch Scmidt-Cassegrain telescope and a soon-to-be-acquired new 16-inch reflector, all funded by private donations. The telescopes will be fitted with photometers, spectrometers, and digital and CCD cameras to pursue observations that would include sun spot and solar magnetic fields, planetary surfaces, asteroid search, variable stars and supernovae. The Center will be integrated with schools, colleges, and community groups for regular observation and small-scale research. Special educational and observing sessions for adults will also be organized. Updates on the development of the Center, which is expected to be functioning by the end of 2015, will be shared and feedback invited on the fostering of

    Renshaw, Steven L.

    While Japan is known more for its contributions to modern astronomy than its archaeoastronomical sites, there is still much about the culture's heritage that is of interest in the study of cultural astronomy. This case study provides an overview of historical considerations necessary to understand the place of astronomy in Japanese society as well as methodological considerations that highlight traditional approaches that have at times been a barrier to interdisciplinary research. Some specific areas of study in the cultural astronomy of Japan are discussed including examples of contemporary research based on interdisciplinary approaches. Japan provides a fascinating background for scholars who are willing to go beyond their curiosity for sites of alignment and approach the culture with a desire to place astronomical iconography in social context.

    Astronomy as a science began with the Ionian philosophers, with whom Greek philosophy and mathematics also began. While the Egyptians and Babylonians had accomplished much of astronomical worth, it remained for the unrivalled speculative genius of the Greeks, in particular, their mathematical genius, to lay the foundations of the true science of astronomy. In this classic study, a noted scholar discusses in lucid detail the specific advances made by the Greeks, many of whose ideas anticipated the discoveries of modern astronomy.Pythagoras, born at Samos about 572 B.C., was probably the first

    Antarctica provides a unique environment for astronomy. The cold, dry and stable air found above the high plateau, as well as the pure ice below, offers new opportunities across the photon & particle spectrum. The summits of the plateau provide the best seeing conditions, the darkest skies and the most transparent atmosphere of any earth-based observing site. Astronomical activities are now underway at four plateau sites: the Amundsen-Scott South Pole Station, Concordia Station at Dome C, Kunlun Station at Dome A and Fuji Station at Dome F, in addition to long duration ballooning from the coastal station of McMurdo. Astronomy conducted includes optical, IR, THz & sub-mm, measurements of the CMBR, solar, as well as high energy astrophysics involving measurement of cosmic rays, gamma rays and neutrinos. Antarctica is also the richest source of meteorites on our planet. An extensive range of site testing measurements have been made over the high plateau.

    As part of the education and public outreach efforts of the NASA JPL Navigator and Spitzer EPO Programs along with the American Astronomical Society and the Astronomical Society of the Pacific, astronomy educators affiliated with the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona are conducting a series of two- and three-day teaching excellence workshops for college faculty. These regional workshops are being held at community colleges around the country and in conjunction with professional society meetings, such as the American Astronomical Society and the American Association of Physics Teachers, and through the infrastructure of the National Science Foundation's Summer Chautauqua Workshop program. These interactive teaching excellence workshops focus on dilemmas astronomy teachers face and develop practical solutions for the troubling issues in curriculum, instruction, and assessment. After reviewing the latest research about how students learn, participants define and set measurable student learning goals and objectives for students in their astronomy courses and construct effective course syllabi reflecting the ASTRO 101 goals publicized by the AAS. To improve instruction, participants learn how to create productive learning environments by using interactive lectures, peer instruction, engaging demonstrations, collaborative groups, tutorials, computer-based laboratories, and observational projects. Participants also learn how to write more effective multiple-choice tests and implement authentic assessment strategies including portfolio assessment, performance tasks, and concept maps. Texts used at the workshop include: (i) Learner-Centered Astronomy Teaching, Slater and Adams, Prentice Hall, 2002; (ii) Great Ideas for Teaching Astronomy, Pompea, Brooks Cole, 2000; Insights into the Universe, Slater and Zeilik, and (iv) Lecture-Tutorials for Introductory Astronomy, Adams, Prather, & Slater, Prentice Hall, 2005.

    2007-01-01

    Fundamental Astronomy gives a well-balanced and comprehensive introduction to the topics of classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. The fifth edition of this successful undergraduate textbook has been extensively modernized and extended in the parts dealing with the Milky Way, extragalactic astronomy and cosmology as well as with extrasolar planets and the solar system (as a consequence of recent results from satellite missions and the new definition by the International Astronomical Union of planets, dwarf planets and small solar-system bodies). Furthermore a new chapter on astrobiology has been added. Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference and entrée for dedicated amateur astronomers.

  2. Astronomy Communication

    2003-07-01

    Astronomers communicate all the time, with colleagues of course, but also with managers and administrators, with decision makers and takers, with social representatives, with the news media, and with the society at large. Education is naturally part of the process. Astronomy communication must take into account several specificities: the astronomy community is rather compact and well organized world-wide; astronomy has penetrated the general public remarkably well with an extensive network of associations and organizations of aficionados all over the world. Also, as a result of the huge amount of data accumulated and by necessity for their extensive international collaborations, astronomers have pioneered the development of distributed resources, electronic communications and networks coupled to advanced methodologies and technologies, often much before they become of common world-wide usage. This book is filling up a gap in the astronomy-related literature by providing a set of chapters not only of direct interest to astronomy communication, but also well beyond it. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy nor in communication techniques while providing specific detailed information, as well as plenty of pointers and bibliographic elements. This book will be very useful for researchers, teachers, editors, publishers, librarians, computer scientists, sociologists of science, research planners and strategists, project managers, public-relations officers, plus those in charge of astronomy-related organizations, as well as for students aiming at a career in astronomy or related space science.

  3. Conceptual frameworks in astronomy

    Science.gov (United States)

    Pundak, David

    2016-06-01

    How to evaluate students' astronomy understanding is still an open question. Even though some methods and tools to help students have already been developed, the sources of students' difficulties and misunderstanding in astronomy is still unclear. This paper presents an investigation of the development of conceptual systems in astronomy by 50 engineering students, as a result of learning a general course on astronomy. A special tool called Conceptual Frameworks in Astronomy (CFA) that was initially used in 1989, was adapted to gather data for the present research. In its new version, the tool included 23 questions, and five to six optional answers were given for each question. Each of the answers was characterized by one of the four conceptual astronomical frameworks: pre-scientific, geocentric, heliocentric and sidereal or scientific. The paper describes the development of the tool and discusses its validity and reliability. Using the CFA we were able to identify the conceptual frameworks of the students at the beginning of the course and at its end. CFA enabled us to evaluate the paradigmatic change of students following the course and also the extent of the general improvement in astronomical knowledge. It was found that the measure of the students’ improvement (gain index) was g = 0.37. Approximately 45% of the students in the course improved their understanding of conceptual frameworks in astronomy and 26% deepened their understanding of the heliocentric or sidereal conceptual frameworks.

  4. Bad Astronomy Goes Hollywood

    Science.gov (United States)

    Plait, P.

    2003-05-01

    It can be argued that astronomy is the oldest of all the sciences, so you'd think that after all this time people would have a pretty good understanding of it. In reality, however, misconceptions about astronomy abound, and even basic concepts are misunderstood. There are many sources of these cosmic misconceptions, including incorrect textbooks, parents and/or teachers who don't understand astronomy and therefore spread misinformation, urban legends, and so on. Perhaps the most pervasive source of bad astronomy is Hollywood. Science fiction movies are enormously popular, but are commonly written and directed by people who don't have even a passing familiarity with astronomy. The smash hit "Armageddon" (the number one box office movie of 1998), for example, used vast quantities of incorrect astronomy in the plot. It reinforced such popular misconceptions as huge asteroids impacting the Earth with little warning, small meteorites being hot when they impact, air existing in space, and that a simple bomb can blow up an asteroid the size of a small moon (even when the bomb is buried only 800 feet deep!). However, movie scenes can be used as a hook that engages the student, helping them learn and remember the correct science. In this talk, I will light-heartedly discuss specific examples of common misinformation, using movie clips, diagrams, and a splash of common sense to show just where Hollywood gets it wrong, and what you can do to help students and the public get it right.

    In this paper, we describe what we have done with regard to astronomy training for physics students. More and more students are interested in astronomy, they spend their summer holidays and spare time in observations and studying the observation data. Some students are familiar with using the telescope for observations, dealing with absorption line features achieved from the observations. Astronomy was selected as the key subject in Guangzhou city and Guangdong province, the laboratory for astronomy science and technology was selected as the key laboratory of Guangzhou city and that for the education department of Guangdong Province. We also provide a master degree programme for astronomy.

  7. Ideas for Citizen Science in Astronomy

    Science.gov (United States)

    Marshall, Philip J.; Lintott, Chris J.; Fletcher, Leigh N.

    2015-08-01

    We review the expanding, internet-enabled, and rapidly evolving field of citizen astronomy, focusing on research projects in stellar, extragalactic, and planetary science that have benefited from the participation of members of the public. These volunteers contribute in various ways: making and analyzing new observations, visually classifying features in images and light curves, exploring models constrained by astronomical data sets, and initiating new scientific enquiries. The most productive citizen astronomy projects involve close collaboration between the professionals and amateurs involved and occupy scientific niches not easily filled by great observatories or machine learning methods: Citizen astronomers are motivated by being of service to science, as well as by their interest in the subject. We expect participation and productivity in citizen astronomy to increase, as data sets get larger and citizen science platforms become more efficient. Opportunities include engaging citizens in ever-more advanced analyses and facilitating citizen-led enquiry through professional tools designed with citizens in mind.

    2010-01-01

    Bring telescope to where the people are! Music and Astronomy Under the Stars is a three-year NASA-funded outreach program at parks during and after concerts and family events - a Halloween Spooky Garden Walk. While there have been many outreach activities and telescope observations at city sidewalks and parks, this program targets a completely different audience - music lovers who attend summer concerts held in community parks. These music lovers who may never have visited a science museum, planetarium, or star party are exposed to telescope observations and astronomy information with no additional travel costs. Music and Astronomy Under the Stars increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. This program includes solar observing before the concerts, telescope observations including a live image projection system, an astronomical video presentation, and astronomy banners/posters. Approximately 500 - 16,000 people attended each event and 25% to 50% of the people at each event participated in the astronomy program. This program also reached underrepresented and underserved groups (women, minorities, older adults). The target audience is 2,900,000 people, which is larger than combined population of Atlanta, Boston, Denver, Minneapolis, and San Francisco. Although eleven events were planned in 2009, two were canceled due to rain and our largest event, the NY Philharmonic in the Park (attended by 67,000 people in 2008), was cancelled for financial reasons. Our largest event in 2009 was the Tanglewood Music Festival, Lenox MA, attended by 16,000 people where 5000 people participated in astronomy activities. The Amateur Observers' Society of NY assisted with the NY concerts and the Springfield STARS club assisted at Tanglewood. 1500 people looked through telescopes at the Halloween program (6000 saw the posters). In 2009 over 15,000 people participated in these astronomy activities which were attended by

  10. Minoan Astronomy

    Blomberg, Mary; Henriksson, Göran

    Of the three great cultures of the ancient eastern Mediterranean — the Babylonian, Egyptian, and Minoan — we have considerable knowledge of the astronomy of the first two through their documents (see relevant sections of this Handbook). Very little written material, however, has survived from Minoan Crete, but the evidence of other impressive archaeological discoveries implies that the inhabitants were on a par with their neighbors and had made similar advances in astronomy. In lieu of written sources, we have used the methods of archaeoastronomy to recover as much as possible about Minoan astronomy. In short, these are measuring the orientations of walls and their opposite horizons at a representative selection of monuments, analyzing the measurements statistically, and comparing the results with digital reconstruction of the positions of significant celestial bodies for the time when the walls were built.

    2017-01-01

    Imagine you are a grad student, at your first conference, and a prominent senior scientist shows interest in your work, and he makes things get way too personal? What would you do? Would you report it? Or would you decide, after a few other instances of harassment, that maybe you shouldn't pursue astronomy? Harassment is under-reported, the policies can be difficult to understand or hard to find, and it can be very intimidating as a young scientist to report it to the proper individuals. The Astronomy Allies Program is designed to help you with these sorts of problems. We are a group of volunteers that will help by doing the following: provide safe walks home during the conference, someone to talk to confidentially, as an intervener, as a resource to report harassment. The Allies are a diverse group of scientists committed to acting as mentors, advocates, and liaisons. The Winter 2015 AAS meeting was the first meeting that had Astronomy Allies, and Astronomy Allies provided a website for information, as well as a twitter, email, and phone number for anyone who needs our help or would like more information. We posted about the Astronomy Allies on the Women In Astronomy blog, and this program resonates with many people: either they want to help, or they have experienced harassment in the past and don't want to see it in the future. Harassment may not happen to most conference participants, but it's wrong, it's against the AAS anti-harassment policy ( http://aas.org/policies/anti-harassment-policy ), it can be very damaging, and if it happens to even one person, that is unacceptable. We intend to improve the culture at conferences to make it so that harassers feel they can't get away with their unprofessional behavior.

  12. Astronomy education in Thailand

    Hutawarakorn, Busaba; Soonthornthum, B.; Kirdkao, T.

    Thailand is one of the developing countries which pursues the goal to advance economy, technology as well as science. Education in Astronomy is considered as a supporting factor, since it is one of the basic sciences which can teach the young generation to understand and conserve their mother nature and at the same time helps to develop analytical thinking. The poster reports the present developments in astronomical education in Thailand which includes (1) current astronomy education in school and university; (2) educational activities outside school; (3) development of programs for teaching astronomy in school (including teacher training); (4) the access of educational resources via internet. Proposals for future development and collaborations will be presented and discussed.

  13. Rescuing Middle School Astronomy

    Science.gov (United States)

    Mayo, L. A.; Janney, D.

    2010-12-01

    There is a crisis in education at the middle school level (Spellings, 2006). Recent studies point to large disparities in middle school performance in schools with high minority populations. The largest disparities exist in areas of math and science. Astronomy has a universal appeal for K-12 students but is rarely taught at the middle school level. When it is taught at all it is usually taught in isolation with few references in other classes such as other sciences (e.g. physics, biology, and chemistry), math, history, geography, music, art, or English. The problem is greatest in our most challenged school districts. With scores in reading and math below national averages in these schools and with most state achievement tests ignoring subjects like astronomy, there is little room in the school day to teach about the world outside our atmosphere. Add to this the exceedingly minimal training and education in astronomy that most middle school teachers have and it is a rare school that includes any astronomy teaching at all. In this presentation, we show how to develop and offer an astronomy education training program for middle school teachers encompassing a wide range of educational disciplines that are frequently taught at the middle school level. The prototype for this program was developed and launched in two of the most challenged and diverse school systems in the country; D.C. Public Schools, and Montgomery County (MD) Public Schools.

    2006-08-01

    At the Astronomy Department of Universidad de Guanajuato, 400 km NW of Mexico City, nine professional astronomers do research and teaching at both graduate and undergraduate level. In addition, in the last few years, this group has carried out astronomy popularization activities at three different sites. First, a rudimentary observatory named "La Azotea" (the roof) on the top of the main building of the University (at Guanajuato centre), which includes a 16-cm refractor in a dome, a couple of XIXth century astronomical instruments, and a classroom with capacity for 50 people. The refractor was out of use for about twelve years but will be fully operational before summer 2006. Second, the "Observatorio de La Luz", 20 kms away from Guanajuato centre, includes a professional 0.6m Cassegrain and a 2m radio telescope, with a 21cm receiver. Finally, on the roof of the Astronomy Department headquarters, an optical 0.4m Dobsonian is available. We also dispose of internet connection everywhere and 6 portable 8-inch telescopes (two at each site), devoted to regular astronomical observations for the general public, specially for scholars. Numerous repair works are currently carried out on the building of "La Azotea", and recently a project to establish there a Centre for Popularization of Astronomy has been approved by the Regional Science Council. The main activities, some of them currently developed at these sites are: (1) A permanent program of astronomical observations for a wide audience. (2) Training in Observational Astronomy for physics undergraduate students. (3) Regular talks on astronomy and other science domains. (4) Summer schools in Astronomy for elementary and high-school teachers. (5) In the near future, the foundation of an amateur society of astronomy.

    The second Python in Astronomy conference will be held from 21-25 March 2016 at the University of Washington eScience Institute in Seattle, WA, USA. Similarly to the 2015 meeting (which was held at the Lorentz Center), we are aiming to bring together researchers, Python developers, users, and educators. The conference will include presentations, tutorials, unconference sessions, and coding sprints. In addition to sharing information about state-of-the art Python Astronomy packages, the workshop will focus on improving interoperability between astronomical Python packages, providing training for new open-source contributors, and developing educational materials for Python in Astronomy. The meeting is therefore not only aimed at current developers, but also users and educators who are interested in being involved in these efforts.

  16. Student Attitudes Towards Public Funding Of Astronomy

    Science.gov (United States)

    Stine, Peter

    2009-01-01

    Research in astronomy is strongly dependent on public (taxpayer) dollars. In this study we examine the attitudes of college students toward funding of astronomy projects. A survey was given to 269 college students prior to taking an introductory astronomy course. Students were given a short test designed to examine misconceptions about astronomy. They were then asked about their willingness to support public funding for astronomy projects. Students with fundamental misconceptions about mundane topics such as the cause of the seasons and phases of the moon were less than half as likely to support public funding of astronomy projects. Results are also reported showing the relationship between a willingness to fund projects and whether the students had experiences including reading books or magazines on astronomy, exposure to astronomy in high school, and using a telescope.

  17. Astronomy across cultures the history of non-Western astronomy

    CERN Document Server

    Xiaochun, Sun

    2000-01-01

    Astronomy Across Cultures: A History of Non-Western Astronomy consists of essays dealing with the astronomical knowledge and beliefs of cultures outside the United States and Europe. In addition to articles surveying Islamic, Chinese, Native American, Aboriginal Australian, Polynesian, Egyptian and Tibetan astronomy, among others, the book includes essays on Sky Tales and Why We Tell Them and Astronomy and Prehistory, and Astronomy and Astrology. The essays address the connections between science and culture and relate astronomical practices to the cultures which produced them. Each essay is well illustrated and contains an extensive bibliography. Because the geographic range is global, the book fills a gap in both the history of science and in cultural studies. It should find a place on the bookshelves of advanced undergraduate students, graduate students, and scholars, as well as in libraries serving those groups.

  19. Astronomy: On the Bleeding Edge of Scholarly Infrastructure

    Science.gov (United States)

    Borgman, Christine; Sands, A.; Wynholds, L. A.

    2013-01-01

    The infrastructure for scholarship has moved online, making data, articles, papers, journals, catalogs, and other scholarly resources nodes in a deeply interconnected network. Astronomy has led the way on several fronts, developing tools such as ADS to provide unified access to astronomical publications and reaching agreement on a common data file formats such as FITS. Astronomy also was among the first fields to establish open access to substantial amounts of observational data. We report on the first three years of a long-term research project to study knowledge infrastructures in astronomy, funded by the NSF and the Alfred P. Sloan Foundation. Early findings indicate that the availability and use of networked technologies for integrating scholarly resources varies widely within astronomy. Substantial differences arise in the management of data between ground-based and space-based missions and between subfields of astronomy, for example. While large databases such as SDSS and MAST are essential resources for many researchers, much pointed, ground-based observational data exist only on local servers, with minimal curation. Some astronomy data are easily discoverable and usable, but many are not. International coordination activities such as IVOA and distributed access to high-level data products servers such as SIMBAD and NED are enabling further integration of published data. Astronomers are tackling yet more challenges in new forms of publishing data, algorithms, visualizations, and in assuring interoperability with parallel infrastructure efforts in related fields. New issues include data citation, attribution, and provenance. Substantial concerns remain for the long term discoverability, accessibility, usability, and curation of astronomy data and other scholarly resources. The presentation will outline these challenges, how they are being addressed by astronomy and related fields, and identify concerns and accomplishments expressed by the astronomers we have

    2007-12-01

    While a foundation of German scientific methods enabled the rapid growth of North American Astronomy in the nineteenth century, during the seventeenth and most of the eighteenth centuries, the colonial men of science looked only to the English mother country for scientific patronage and guidance. An essay on fundamental astronomy appeared in one of the annual colonial almanacs as early as 1656, telescopic observations were made about 1660 and the first original colonial astronomical work was published by Thomas Danforth on the comet of 1664. By 1671 the Copernican ideas were so espoused at Harvard College that a physics class refused to read a Ptolemaic textbook when it was assigned to them by a senior instructor. At least in the Cambridge-Boston area, contemporary colonialist had access to the most recent scientific publications from the mother country. Observations of the great comet of 1680 by the Almanac maker, John Foster, reached Isaac Newton and were used and gratefully acknowledged in his Principia. During the seventeenth century the colonial interest in astronomy was more intense than it was for other sciences but colonists still occupied a position in the scientific backwater when compared with contemporary European scientists. Nevertheless, the science of astronomy was successfully transplanted from England to North America in the seventeenth century.

    The Direccion General de Divulgacion de la Ciencia is part of Mexico's National University; its purpose is science outreach. Most of its activities are dedicated to school level audiences; nevertheless due to the speed of science development, courses are given for teachers. The astronomy curricula includes: new results in astronomy research, general astrophysics and tools to teach astronomy. The courses offer twelve two hour long sessions. An astronomy researcher delivers a lecture and teachers are trained to use hands on activity. Beginning last in 2007 it has focused on Galileo. It addressed the way he was modern scientist, he observed and made experiments and wrote his results in common language. Year 2009 is a perfect incentive to carry out activities with teachers and keep them busy organizing telescope construction and observations during and after Galileo's commemoration. A book was written specially for them on the experiments Galileo made. In this book they can find interesting hand-on activities with materials that are readily available. (Los experimentos de Galileo, Silvia Torres y Consuelo Doddoli, Correo del Maestro, 2008, in press.) The magazine Correo del Maestro holds many articles written by the author on astronomical activities aimed to teachers.

  2. Chaco astronomies

    Martín López, Alejandro

    2015-08-01

    This presentation discusses the result of 18 years of ethnographic and ethnohistorical studies on Chaco astronomies. The main features of the systems of astronomical knowledge of the Chaco Aboriginal groups will be discussed. In particular we will discuss the relevance of the Milky Way, the role of the visibility of the Pleiades, the ways in which the celestial space is represented, the constitution of astronomical orientations in geographic space, etc. We also address a key feature of their vision of the cosmos: the universe is seen by these groups as a socio-cosmos, where humans and non-humans are related. These are therefore actually socio-cosmologies. We will link this to the theories of Chaco Aboriginal groups about power and political relations.We will discuss how the study of Aboriginal astronomies must be performed along with the studies about astronomies of Creole people and European migrants, as well as anthropological studies about the science teaching in the formal education system and by the mass media. In this form we will discuss the relevance of a very complex system of interethnic relations for the conformation of these astronomical representations and practices.We will also discuss the general methodological implications of this case for the ethnoastronomy studies. In particular we will talk about the advantages of a study of regional scope and about the key importance of put in contact the ethnoastronomy with contemporary issues in social sciences.We also analyze the importance of ethnoastronomy studies in relation to studies of sociology of science, especially astronomy. We also study the potential impact on improving formal and informal science curricula and in shaping effective policies to protect the tangible and intangible astronomical heritage in a context of respect for the rights of Aboriginal groups.

    Here we report on the first successful exoplanet transit observation with the Stratospheric Observatory for Infrared Astronomy (SOFIA). We observed a single transit of the hot Jupiter HD 189733 b, obtaining two simultaneous primary transit lightcurves in the B and z' bands as a demonstration of SOFIA's capability to perform absolute transit photometry. We present a detailed description of our data reduction, in particular the correlation of photometric systematics with various in-flight parameters unique to the airborne observing environment. The derived transit depths at B and z' wavelengths confirm a previously reported slope in the optical transmission spectrum of HD 189733 b. Our results give new insights to the current discussion about the source of this Rayleigh scattering in the upper atmosphere and the question of fixed limb darkening coefficients in fitting routines.

    something of a minor tourist attraction, he later recalled. Using electronics he designed and built that pushed the technical capabilities of the era, Reber succeeded in detecting "cosmic static" in 1939. In 1941, Reber produced the first radio map of the sky, based on a series of systematic observations. His radio-astronomy work continued over the next several years. Though not a professional scientist, his research results were published in a number of prestigious technical journals, including Nature, the Astrophysical Journal, the Proceedings of the Institute of Radio Engineers and the Journal of Geophysical Research. Reber also received a number of honors normally reserved for scientists professionally trained in astronomy, including the American Astronomical Society's Henry Norris Russell Lectureship and the Astronomical Society of the Pacific's Bruce Medal in 1962, the National Radio Astronomy Observatory's Jansky Lectureship in 1975, and the Royal Astronomical Society's Jackson-Gwilt Medal in 1983. Reber's original dish antenna now is on display at the National Radio Astronomy Observatory's site in Green Bank, West Virginia, where Reber worked in the late 1950s. All of his scientific papers and records as well as his personal and scientific correspondence are held by the NRAO, and will be exhibited in the observatory's planned new library in Charlottesville, Virginia. Reber's amateur-radio callsign, W9GFZ, is held by the NRAO Amateur Radio Club. This callsign was used on the air for the first time since the 1930s on August 25, 2000, to mark the dedication of the Robert C. Byrd Green Bank Telescope. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

    2013-01-01

    This 6th edition of “Tools of Radio Astronomy”, the most used introductory text in radio astronomy, has been revised to reflect the current state of this important branch of astronomy. This includes the use of satellites, low radio frequencies, the millimeter/sub-mm universe, the Cosmic Microwave Background and the increased importance of mm/sub-mm dust emission. Several derivations and presentations of technical aspects of radio astronomy and receivers, such as receiver noise, the Hertz dipole and  beam forming have been updated, expanded, re-worked or complemented by alternative derivations. These reflect advances in technology. The wider bandwidths of the Jansky-VLA and long wave arrays such as LOFAR and mm/sub-mm arrays such as ALMA required an expansion of the discussion of interferometers and aperture synthesis. Developments in data reduction algorithms have been included. As a result of the large amount of data collected in the past 20 years, the discussion of solar system radio astronomy, dust em...

  6. The Status of History of Astronomy in America

    Dick, Steven J.

    1994-12-01

    The retiring Chairman of the HAD (Historical Astronomy Division) reviews the status of the field of history of astronomy in America. Since the founding of the Division some 15 years ago, the variety of HAD-sponsored thematic sessions and contributed papers demonstrates in itself the wide scope of the field, ranging from archaeoastronomy, to comparative studies of "astronomy and the State" in the United States and the Soviet Union, to conceptual and institutional themes and the role of history in teaching. A great deal more remains to be done in terms of research on individuals, institutions, instruments and concepts, particularly archival work, before any kind of synthetic history of astronomy in America can be written. History of astronomy is valuable to astronomers and the AAS for at least three reasons: 1) historical data, including observations of supernovae, comets, and the positions of stars and planets, are of use to modern astronomy; 2) quite aside from the application of historical data, the field has an intrinsic interest of its own, and provides a perspective across many astronomical specialties that illuminates the nature of astronomical practice, progress and culture; and 3) the Division provides a central focus for discussion and preservation of the Society's own history and archives. The HAD consists of a unique blend of astronomers and historians of science, who often have different approaches to history of astronomy, each offering complementary analytical and technical skills. The HAD News, the HASTRO e-mail Discussion Group, the special interest group in history of astronomy in the History of Science Society, and the biennial history of astronomy workshops all provide forums for advancing the study of history of astronomy in the United States. The newly relocated Center for the History of Physics of the American Institute of Physics provides important archival and oral history resources. History of astronomy in America should also be placed in the

    My successful outreach program venues include: outdoor concerts and festivals; the US National Mall; churches, synagogues, seminaries, or clergy conferences; the Ronald McDonald Houses of Long Island and Chicago; the Winthrop U. Hospital Children’s Medical Center the Fresh Air Fund summer camps (low-income and special needs); a Halloween star party (costumed kids look through telescopes); a Super Bowl Star Party (targeting women); Science Festivals (World, NYC; Princeton U.; the USA Science and Engineering Festival); and the NYC Columbus Day Parade. Information was also provided about local science museums, citizen science projects, astronomy educational sites, and astronomy clubs to encourage lifelong learning. In 2010 I created Astronomy Festival on the National Mall (co-sponsored by the White House Office of Science and Technology Policy) with the participation of astronomy clubs, scientific institutions and with Tyco Brahe, Johannes Kepler, and Caroline Herschel making guest appearances. My programs include solar, optical, and radio telescope observations, hands-on activities, a live image projection system; large outdoor posters and banners; videos; hands-on activities, and edible astronomy demonstrations.My NASA-funded Music and Astronomy Under the Stars (MAUS) program (60 events 2009 - 2013) reached 50,000 music lovers at local parks and the Central Park Jazz, Newport Folk, Ravinia, or Tanglewood Music Festivals with classical, folk, pop/rock, opera, Caribbean, or county-western concerts assisted by astronomy clubs. Yo-Yo-Ma, the Chicago and Boston Symphony Orchestras, Ravi Coltrane, Esperanza Spalding, Phish, Blood Sweat and Tears, Deep Purple, Tony Orlando, and Wilco performed at these events.

    We describe the application of data mining algorithms to research problems in astronomy. We posit that data mining has always been fundamental to astronomical research, since data mining is the basis of evidence-based discovery, including classification, clustering, and novelty discovery. These algorithms represent a major set of computational tools for discovery in large databases, which will be increasingly essential in the era of data-intensive astronomy. Historical examples of data mining...

  11. Thread Safe Astronomy

    CERN Document Server

    Seaman, Robert

    2008-01-01

    Observational astronomy is the beneficiary of an ancient chain of apprenticeship. Kepler's laws required Tycho's data. As the pace of discoveries has increased over the centuries, so has the cadence of tutelage (literally, "watching over"). Naked eye astronomy is thousands of years old, the telescope hundreds, digital imaging a few decades, but today's undergraduates will use instrumentation yet unbuilt - and thus, unfamiliar to their professors - to complete their doctoral dissertations. Not only has the quickening cadence of astronomical data-taking overrun the apprehension of the science within, but the contingent pace of experimental design threatens our capacity to learn new techniques and apply them productively. Virtual technologies are necessary to accelerate our human processes of perception and comprehension to keep up with astronomical instrumentation and pipelined dataflows. Necessary, but not sufficient. Computers can confuse us as efficiently as they illuminate. Rather, as with neural pathways e...

    2007-12-01

    We have examined the improvement of ride quality and the reduction of riding fatigue brought about by the active control of the seat suspension of small vehicles such as one-seater electric automobiles. A small active seat suspension, which is easy to install, was designed and manufactured for one-seater electric automobiles. For the actuator, a maintenance-free voice coil motor used as a direct drive was adopted. For fundamental considerations, we designed a one-degree-of-freedom model for the active seat suspension system. Then, we designed a disturbance cancellation control system that includes the observer for a two-degree-of-freedom model. In an actual driving test, a test road, in which the concavity and convexity of an actual road surface were simulated using hard rubber, was prepared and the control performance of vertical vibrations of the seat surface during driving was examined. As a result, in comparison with the one-degree-of-freedom control system, it was confirmed that the control performance was improved by the two-degree-of-freedom control system that includes the observer.

Formerly known as "The Asterisk," the site's new design is called "Starship Asterisk" and now declares its forums to be places on a starship, with the current APOD considered as appearing on the main view screen on the Bridge. A central "mission" of Starship Asterisk is to support APOD in various ways. Toward this end, the Bridge forum exists primarily for the (archived) discussion of that day's APOD, the Observation Deck forum facilitates APOD image submissions, and the Library creates a forum where no student question about astronomy is considered to be too easy or too hard. Additionally, Starship Asterisk now includes an astronomy news-oriented links forum titled the Communications Center, a citizen science-oriented links collection called the Science Labs, and classrooms including a free online, textbook-free Astro 101 course, taught by the author, complete with video lectures and powerpoint slides. Typically, over 1,000 astronomy enthusiasts will browse Starship Asterisk on any given day. Although the vast majority of readers prefer to browse anonymously, the site has now garnered over 60,000 posts. A small but dedicated group of volunteer "officers" administer the bulletin board, answer questions about astronomy from curious APOD readers, and openly discuss various astronomy topics, frequently with intended humor. Perhaps surprisingly, the majority of volunteer officers tend NOT to be professional astronomers, but typically quite knowledgeable retirees exercising a lifelong interest in astronomy.

  14. Critical Issues in the Philosophy of Astronomy and Cosmology

    Although the philosophy of science and of specific sciences such as physics, chemistry, and biology are well-developed fields with their own books and journals, the philosophy of astronomy and cosmology have received little systematic attention. At least six categories of problems may be identified in the astronomical context: 1) the nature of reasoning, including the roles of observation, theory, simulation, and analogy, as well as the limits of reasoning, starkly evident in the anthropic principle, fine-tuning, and multiverse controversies; 2) the often problematic nature of evidence and inference, especially since the objects of astronomical interest are for the most part beyond experiment and experience;3) the influence of metaphysical preconceptions and non-scientific worldviews on astronomy, evidenced, for example in the work of Arthur S. Eddington and many other astronomers; 4) the epistemological status of astronomy and its central concepts, including the process of discovery, the problems of classification, and the pitfalls of definition (as in planets); 5) the role of technology in shaping the discipline of astronomy and our view of the universe; and 6) the mutual interactions of astronomy and cosmology with society over time. Discussion of these issues should draw heavily on the history of astronomy as well as current research, and may reveal an evolution in approaches, techniques, and goals, perhaps with policy relevance. This endeavor should also utilize and synergize approaches and results from philosophy of science and of related sciences such as physics (e.g. discussions on the nature of space and time). Philosophers, historians and scientists should join this new endeavor. A Journal of the Philosophy of Astronomy and Cosmology (JPAC) could help focus attention on their studies.

  15. Microstructural observations of HFIR-irratiated austenitic stainless steels including welds from JP9-16

    Energy Technology Data Exchange (ETDEWEB)

    Sawai, T.; Shiba, K.; Hishinuma, A.

    1996-04-01

    Austenitic stainless steels, including specimens taken from various electron beam (EB) welds, have been irradiated in HFIR Phase II capsules, JP9-16. Fifteen specimens irradiated at 300, 400, and 500{degrees}C up to 17 dpa are so far examined by a transmission electron microscope (TEM). In 300{degrees}C irradiation, cavities were smaller than 2nm and different specimens showed little difference in cavity microstructure. At 400{degrees}C, cavity size was larger, but still very small (<8 nm). At 500{degrees}C, cavity size reached 30 nm in weld metal specimens of JPCA, while cold worked JPCA contained a small (<5 nm) cavities. Inhomogeneous microstructural evolution was clearly observed in weld-metal specimens irradiated at 500{degrees}C.

    The Ephemerides Association was founded last year by a PhD student in Astronomy. The association is devoted to the promotion and advancement of knowledge of the universe through research and education.The main activities of the association are scientific meetings, the planning and realization of scientific projects, the support of the scientific activities of its members, and the dissemination of related information among members and other interested persons.The association targets the disadvantaged zones of the Paris suburbs.The main issue was how to bring astronomy in those places. In the suburbs, since most of the youth are poor, most leisure activities like cinema are out of your reach. Thus, mostly of them will play football or basketball outside.We decided to go to meet young people who find themselves together in the evening. We prepare the telescope as well as the fasicules to start the observation of the planets. The discussion finally lead to their career plans and aspirations. Astronomy has become a tool to address societal issues. We present our results after one year of activity.

  17. Observations of planetary transits made in Ireland in the 18th Century and the development of astronomy in Ireland

    Butler, C. J.

    2005-04-01

    We review the small number of known observations of planetary transits made in Ireland in the 18th century with particular reference to the 1769 observations of Venus by Charles Mason. Though inconclusive, there is evidence to suggest that planetary transits were instrumental in the foundation of at least one of the principal observatories in Ireland. In addition, we note the close personal involvement and the contributions of Nevil Maskelyne, the prime mover of the UK 1769 Transit observations, in the design and equipment of these observatories.

    2002-01-01

    The Far Ultraviolet Spectroscopic Explorer (FUSE) is studying a wide range of astronomical problems in the 905-1187 Angstrom wavelength region through the use of high resolution spectroscopy. The FUSE bandpass forms a nearly optimal complement to the spectral coverage provided by the Hubble Space Telescope (HST), which extends down to approximately 1170 Angstroms. The photoionization threshold of atomic hydrogen (911 Angstroms) sets a natural short-wavelength limit for the FUV. FUSE was launched in June 1999 from Cape Canaveral, Florida, on a Delta II rocket into a 768 km circular orbit. Scientific observations started later that year. This spectral region is extremely rich in spectral diagnostics of astrophysical gases over a wide range of temperatures (100 K to over 10 million K). Important strong spectral lines in this wavelength range include those of neutral hydrogen, deuterium, nitrogen, oxygen, and argon (H I, D I, N I, O I, and Ar I), molecular hydrogen (H2), five-times ionized oxygen (O VI), and several ionization states of sulfur (S III - S VI). These elements are essential for understanding the origin and evolution of the chemical elements, the formation of stars and our Solar System, and the structure of galaxies, including our Milky Way. FUSE is one of NASA's Explorer missions and a cooperative project of NASA and the space agencies of Canada and France. These missions are smaller, more scientifically focused missions than the larger observatories, like Hubble and Chandra. FUSE was designed, built and operated for NASA by the Department of Physics and Astronomy at Johns Hopkins University. Hundreds of astronomers world-wide are using FUSE for a wide range of scientific research. Some of the important scientific discoveries from the first two years of the mission are described.

  19. Astronomy in the City for Astronomy Education

    Ros, Rosa M.; Garc, Beatriz

    2016-10-01

    Astronomy is part of our culture. Astronomy cannot be isolated in a classroom, it has to be integrated in the normal life of teachers and students. ``Astronomy in the city'' is an important part of NASE (Network for Astronomy School Education) (Ros & Hemenway 2012). In each NASE course we introduce a ``working group session'' chaired by a local expert in cultural astronomy. The chair introduces several examples of astronomy in their city and after that, the participants have the opportunity to discuss and mention several similar examples. After this session all participants visit one or two sites proposed and introduced by the chair. After more than 5 years using this method we visited and discovered several examples of astronomy in the city: •Astronomy in ancient typical clothes. •Archaeological temples oriented according to the sunrise or set. •Petroglyphs with astronomical meaning. •Astronomy in monuments. •Sundials. •Oriented Colonial churches. •Astronomy in Souvenirs. In any case, teachers and students discover that Astronomy is part of their everyday life. They can take into account the Sun's path when they park their car or when they take a bus ``what is the best part in order to be seat in the shadow during the journey?'' The result is motivation to go with ``open eyes'' when they are in the street and they try to get more and more information about their surroundings. In summary, one of the main activities is to introduce local cultural aspects in NASE astronomy courses. The participants can discover a new approach to local culture from an astronomical point of view.

  20. Freshman Seminars: Interdisciplinary Engagements in Astronomy

    Hemenway, M. K.

    2006-08-01

    The Freshman Seminar program at the University of Texas is designed to allow groups of fifteen students an engaging introduction to the University. The seminars introduce students to the resources of the university and allow them to identify interesting subjects for further research or future careers. An emphasis on oral and written communication by the students provides these first-year students a transition to college-level writing and thinking. Seminar activities include field trips to an art museum, a research library, and the Humanities Research Center rare book collection. This paper will report on two seminars, each fifteen weeks in length. In "The Galileo Scandal" students examine Galileo's struggle with the church (including a mock trial). They perform activities that connect his use of the telescope and observations to astronomical concepts. In "Astronomy and the Humanities" students analyze various forms of human expression that have astronomical connections (art, drama, literature, music, poetry, and science fiction); they perform hands-on activities to reinforce the related astronomy concepts. Evaluation of the seminars indicates student engagement and improvement in communication skills. Many of the activities could be used independently to engage students enrolled in standard introductory astronomy classes.

  1. Linear regression in astronomy. I

    Isobe, Takashi; Feigelson, Eric D.; Akritas, Michael G.; Babu, Gutti Jogesh

    1990-01-01

    Five methods for obtaining linear regression fits to bivariate data with unknown or insignificant measurement errors are discussed: ordinary least-squares (OLS) regression of Y on X, OLS regression of X on Y, the bisector of the two OLS lines, orthogonal regression, and 'reduced major-axis' regression. These methods have been used by various researchers in observational astronomy, most importantly in cosmic distance scale applications. Formulas for calculating the slope and intercept coefficients and their uncertainties are given for all the methods, including a new general form of the OLS variance estimates. The accuracy of the formulas was confirmed using numerical simulations. The applicability of the procedures is discussed with respect to their mathematical properties, the nature of the astronomical data under consideration, and the scientific purpose of the regression. It is found that, for problems needing symmetrical treatment of the variables, the OLS bisector performs significantly better than orthogonal or reduced major-axis regression.

  2. EM Monitoring of Crustal Processes Including the Use of the Network-MT Observations

    Science.gov (United States)

    Uyeshima, Makoto

    2007-05-01

    There are several kinds of coupling mechanisms which can convert mechanical, chemical or thermal energies due to seismic or volcanic activities into electromagnetic energies. As a result of concentrated efforts in laboratory and theoretical research, the basic relationship between the intensity of electromagnetic sources and changes in mechanical, chemical and thermal state is becoming established. Also with the progress of the electromagnetic simulation techniques, it has been possible to evaluate in situ sensitivity. Based on this progress and also due to extensive improvement in measuring techniques, many field experiments have been performed to elucidate subsurface geophysical processes underlying the preparation stage, onset, and subsequent healing stage of earthquakes and volcanic eruptions. In volcanic studies, many studies have reported the measurement of electromagnetic signals which were successfully interpreted in terms of various driving mechanisms. Although there have been numerous reports about the existence of precursory electromagnetic signals in seismic studies, only a few of them could be successfully explained by the proposed mechanisms, whereas coseismic phenomena are often consistent with those mechanisms including the absence of detectable signals. In many cases, one or two orders of higher sensitivity were required, especially for precursory signals. Generally, electromagnetic methods are more sensitive to near-surface phenomena. It will be necessary to discriminate electromagnetic signals due to these near-surface sources, which often possess no relationship with the crustal activities. Further efforts to enhance in situ sensitivity through improvements in observation techniques and in data processing techniques are recommended. At the same time, multi-disciplinary confirmation against the validity of electromagnetic phenomena will inevitably be necessary. A Network-MT observation technique has been developed to determine large-scale deep

    2007-08-01

    The most important discovery, which enriched our knowledge of ancient astronomy in Armenia, was the complex of platforms for astronomical observations on the Small Hill of Metzamor, which may be called an ancient “observatory”. Investigations on that Hill show that the ancient inhabitants of the Armenian Highlands have left us not only pictures of celestial bodies, but a very ancient complex of platforms for observing the sky. Among the ancient monuments in Armenia there is a megalithic monument, probably, being connected with astronomy. 250km South-East of Yerevan there is a structure Zorats Kar (Karahunge) dating back to II millennium B.C. Vertical megaliths many of which are more than two meters high form stone rings resembling ancient stone monuments - henges in Great Britain and Brittany. Medieval observations of comets and novas by data in ancient Armenian manuscripts are found. In the collection of ancient Armenian manuscripts (Matenadaran) in Yerevan there are many manuscripts with information about observations of astronomical events as: solar and lunar eclipses, comets and novas, bolides and meteorites etc. in medieval Armenia.

    2010-01-01

    Electrostatic solitary waves (ESWs) are observed in the vicinity of the magnetic null of the widely studied magnetic reconnection taking place at the near-earth tail when current sheet becomes dramatic thinning during substorm time on 1 October 2001. We use the Imada method for the 2-D reconnection model and study the characteristics of ESWs near the X-line region and the magnetic null points. The result shows that the amplitude of the observed ESWs in the vicinity of X-line region ranges from 0.1 mV/m to 5 mV/m, and the amplitude is larger near the magnetic null points. The generation mechanism and the role of ESWs associated with magnetic reconnection are also discussed.

    Einstein's General Theory of Relativity is our best classical description of gravity, and informs modern astronomy and astrophysics at all scales: stellar, galactic, and cosmological. Among its surprising predictions is the existence of gravitational waves -- ripples in space-time that carry energy and momentum away from strongly interacting gravitating sources. In my talk, I will give an overview of the properties of this radiation, recent breakthroughs in computational physics allowing us to calculate the waveforms from galactic mergers, and the prospect of direct observation with interferometric detectors such as LIGO and LISA.

  14. The Durability and Fragility of Knowledge Infrastructures: Lessons Learned from Astronomy

    CERN Document Server

    Borgman, Christine L; Sands, Ashley E; Golshan, Milena S

    2016-01-01

    Infrastructures are not inherently durable or fragile, yet all are fragile over the long term. Durability requires care and maintenance of individual components and the links between them. Astronomy is an ideal domain in which to study knowledge infrastructures, due to its long history, transparency, and accumulation of observational data over a period of centuries. Research reported here draws upon a long-term study of scientific data practices to ask questions about the durability and fragility of infrastructures for data in astronomy. Methods include interviews, ethnography, and document analysis. As astronomy has become a digital science, the community has invested in shared instruments, data standards, digital archives, metadata and discovery services, and other relatively durable infrastructure components. Several features of data practices in astronomy contribute to the fragility of that infrastructure. These include different archiving practices between ground- and space-based missions, between sky su...

Trained teams spent four days in 120 Ohio dental practices observing 3751 patient encounters with dentists and hygienists. Direct observation of practice characteristics, procedures performed, and how procedure and nonprocedure time was utilized during patient visits was recorded using a modified Davis Observation Code that classified patient contact time into 24 behavioral categories. Dentist, hygienist, and patient characteristics were gathered by questionnaire. The most common nonprocedure behaviors observed for dentists were chatting, evaluation feedback, history taking, and answering patient questions. Hygienists added preventive counseling. We distinguish between preventive procedures and counseling in actual dental offices that are members of a practice-based research network. Almost a third of the dentist’s and half of the hygienist’s patient contact time is utilized for nonprocedure behaviors during patient encounters. These interactions may be linked to patient and practitioner satisfaction and effectiveness of self-care instruction.Keywords: dental practice, dental practice core activities, direct observation of dental practice, Dental Davis Observation Code, dentist, hygienist patient behaviors

  19. Distance Education with a Computerized Astronomy Laboratory

    Science.gov (United States)

    Connors, Martin

    1992-12-01

    Distance Education is the presentation of an educational curriculum through self-study materials supplemented by regular contact with an instructor. As such it is suitable for offering educational opportunities to students in widely dispersed locations typical of Canada. Since 1989 Athabasca University has offered Science 280, Introduction to Astronomy and Astrophysics, as a broad introduction to Astronomy at a pre-calculus level. The course includes a computer-based laboratory (observing simulation) set done in students' homes. The laboratory allows simulation of naked eye astronomical observations, starting with the motions of the sun and moon. The logical jump to motions not apparently centered on Earth (planetary retrograde motion and periods) seems to present difficulty to students. Stellar proper motions are made observable by the use of long observing intervals of up to 30000 years. The distribution of nearby stars in space is studied through use of stellar color and the assumption that all stars are on the Main Sequence. The erroneous results which this engenders are not recognized as such by most students, who happily submit reports with red stars at .02 parsec distance. Star counts enable rough determination of Galactic structure. Widespread availability of PC-compatible computers has enabled distance education to bring astronomical education, including an 'observational' component, to Canadians who otherwise would not have access to it.

  20. Astronomy in Iran

    Sobouti, Y.

    2006-08-01

    Institute for Advanced Studies in Basic Sciences, Zanjan, Iran In spite of her renowned pivotal role in the advancement of astronomy on the world scale during 9th to 15th centuries, Iran's rekindled interest in modern astronomy is a recent happening. Serious attempts to introduce astronomy into university curricula and to develop it into a respectable and worthwhile field of research began in the mid 60's. The pioneer was Shiraz University. It should be credited for the first few dozens of astronomy- and astrophysics- related research papers in international journals, for training the first half a dozen of professional astronomers and for creating the Biruni Observatory. Here, I take this opportunity to acknowledge the valuable advice of Bob Koch and Ed Guinan, then of the University of Pennsylvania, in the course of the establishment of this observatory. At present the astronomical community of Iran consists of about 65 professionals, half university faculty members and half MS and PhD students. The yearly scientific contribution of its members has, in the past three years, averaged to about 15 papers in reputable international journals, and presently has a healthy growth rate. Among the existing observational facilities, Biruni Observatory with its 51 cm Cassegrain, CCD cameras, photometers and other smaller educational telescopes, is by far the most active place. Tusi Observatory of Tabriz University has 60 and 40 cm Cassegrains, and a small solar telescope. A number of smaller observing facilities exist in Meshed, Zanjan, Tehran, Babol and other places. The Astronomical Society of Iran (ASI), though some 30 years old, has expanded and institutionalized its activities since early 1990's. ASI sets up seasonal schools for novices, organizes annual colloquia and seminars for professionals and supports a huge body of amateur astronomers from among high school and university students. Over twenty of ASI members are also members of IAU and take active part in its

    The Reusable Astronomy Portal (TRAP) aims to provide a common platform for rapidly deploying Astronomy Archives to the web. TRAP is currently under development for both the VAO Data Discovery Portal and the MAST Multi-Mission Portal (Figure 1). TRAP consists of 2 major software packages: the TRAP Client and the TRAP Server. The TRAP framework allows developers to deploy the Server, connect to data resources, then focus on building custom tools for the Client. TRAP is built upon proven industry technologies including the Ext/JS JavaScript Component Library, Mono.NET Web Services, and JSON message based APIs. The multi-layered architecture of TRAP decouples each layer: Client, Service and Data Access, enabling each to evolve independently over time. Although currently deployed to provide astronomy science data access, the TRAP architecture is flexible enough to thrive in any distributed data environment.

    Over the next decade we will witness the development of a new infrastructure in support of data-intensive scientific research, which includes Astronomy. This new networked environment will offer both challenges and opportunities to our community and has the potential to transform the way data are described, curated and preserved. Based on the lessons learned during the development and management of the ADS, a case is made for adopting the emerging technologies and practices of the Semantic Web to support the way Astronomy research will be conducted. Examples of how small, incremental steps can, in the aggregate, make a significant difference in the provision and repurposing of astronomical data are provided.

    In order to process different kinds of observing data with different precisions, a new solution model of nonlinear dynamic integral least squares adjustment was put forward, which is not dependent on their derivatives. The partial derivative of each component in the target function is not computed while iteratively solving the problem. Especially when the nonlinear target function is more complex and very difficult to solve the problem, the method can greatly reduce the computing load.

Observing these signals can bring new, and often very precise, information about their sources across vast stretches of cosmic time. In this talk we will focus on thee opening of this gravitational-wave window on the universe, highlighting new opportunities for discovery and multi-messenger astronomy.

    Professor Orchiston is a foremost authority on the subject of New Zealand astronomy, and here are the collected papers of his fruitful studies in this area, including both those published many years ago and new material.  The papers herein review traditional Maori astronomy, examine the appearance of nautical astronomy practiced by Cook and his astronomers on their various stopovers in New Zealand during their three voyagers to the South Seas, and also explore notable nineteenth century New Zealand observatories historically, from significant telescopes now located in New Zealand to local and international observations made during the 1874 and 1882 transits of Venus and the nineteenth and twentieth century preoccupation of New Zealand amateur astronomers with comets and meteors. New Zealand astronomy has a truly rich history, extending from the Maori civilization in pre-European times through to the years when explorers and navigators discovered the region, up to pioneering research on the newly emerging fie...

    Full Text Available Abstract Background The aim of this study was to determine which behavioral factors to include in guidelines for the Japanese public to achieve an acceptable level of oral healthiness. The objective was to determine the relationship between oral health related behaviors and symptoms related to oral disease and tooth loss in a Japanese adult community. Methods Oral health status and lifestyle were investigated in 777 people aged 20 years and older (390 men and 387 women. Subjects were asked to complete a postal questionnaire concerning past diet and lifestyle. The completed questionnaires were collected when they had health examinations. The 15 questions included their preference for sweets, how many between-meal snacks they usually had per day, smoking and drinking habits, presence of oral symptoms, and attitudes towards dental visits. Participants were asked about their behaviors at different stages of their life. The oral health examinations included examination of the oral cavity and teeth performed by dentists using WHO criteria. Odds ratios were calculated for all subjects, all 10 year age groups, and for subjects 30 years or older, 40 years or older, 50 years or older, and 60 years or older. Results Frequency of tooth brushing (OR = 3.98, having your own toothbrush (OR = 2.11, smoking (OR = 2.71 and bleeding gums (OR = 2.03 were significantly associated with number of retained teeth in males. Frequency of between-meal snacks was strongly associated with number of retained teeth in females (OR = 4.67. Having some hobbies (OR = 2.97, having a family dentist (OR = 2.34 and consulting a dentist as soon as symptoms occurred (OR = 1.74 were significantly associated with number of retained teeth in females. Factors that were significantly associated with tooth loss in both males and females included alcohol consumption (OR = 11.96, males, OR = 3.83, females, swollen gums (OR = 1.93, males, OR = 3.04, females and toothache (OR = 3.39, males, OR

    2006-08-01

    In the IAU resolution on the Value of Astronomy Education, passed by the IAU's General Assembly in 2003, it was recommended: to include astronomy in school curricula, to assist schoolteachers in their training and backup, and to inform teachers about available resources. The aim of this Special Session 2 on "Innovation in Teaching/Learning Astronomy" is to contribute to the implementation of these recommendations, introducing innovative points of view regarding methods of teaching and learning. Astronomers from all countries—developed or developing—will be equally interested. New methods of dissemination of information are making big changes in the opportunity of spreading astronomical knowledge. The World Wide Web continues to expand its reach, and the Astronomy Picture of the Day reaches the homepage of millions. The new phenomenon of podcasts is spreading rapidly. Astronomy attracts many young people to education in important fields in science and technology. But in many countries, astronomy is not part of the standard curriculum, and teachers do not receive adequate education and support. Still, many scientific and educational societies and government agencies have produced materials and educational resources in astronomy for all educational levels. Technology is used in astronomy both for obtaining observations and for teaching. In any case, it is useful to take their special opportunity to learn about the situation in different countries, to exchange opinions, and to collect information in order to continue, over at least the next triennium, the activities related to promoting astronomy throughout the world. In particular, we would like to invite all participants to explain their positive original experiences so they can be adapted for other regions. Everyone is invited to exchange their initiatives and to try to involve other countries in common projects. All of us are in the same boat. http://www.communicatingastronomy.org/innovation2006/

    2003-10-01

    This book is the fourth volume under the title Organizations and Strategies in Astronomy (OSA). These OSA Books are intended to cover a large range of fields and themes. In practice, one could say that all aspects of astronomy-related life and environment are considered in the spirit of sharing specific expertise and lessons learned. This book offers a unique collection of chapters dealing with socio-dynamical aspects of the astronomy (and related space sciences) community: characteristics of organizations, society activities, strategies for development, operational techniques, observing practicalities, environmental constraints, educational policies, public outreach, journal and magazine profiles, publication studies, electronic-media problematics, research communication, evaluation and selection procedures, research indicators, national policies and specificities, expertise sharing, contemporary history, and so on. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy while providing specific detailed information and sometimes enlightening 'lessons learned' sections. The book concludes with an updated bibliography of publications related to socio-astronomy and to the interactions of the astronomy community with the society at large. This book will be most usefully read by researchers, teachers, editors, publishers, librarians, sociologists of science, research planners and strategists, project managers, public-relations officers, plus those in charge of astronomy-related organizations, as well as by students aiming at a career in astronomy or related space science.

    Slater, Timothy F.

    2015-01-01

    Filling a needed scholarly publishing avenue for astronomy education researchers and earth science education researchers, the Journal of Astronomy & Earth Sciences Education - JAESE published its first volume and issue in 2014. The Journal of Astronomy & Earth Sciences Education - JAESE is a scholarly, peer-reviewed scientific journal publishing original discipline-based education research and evaluation, with an emphasis of significant scientific results derived from ethical observations and systematic experimentation in science education and evaluation. International in scope, JAESE aims to publish the highest quality and timely articles from discipline-based education research that advance understanding of astronomy and earth sciences education and are likely to have a significant impact on the discipline or on policy. Articles are solicited describing both (i) systematic science education research and (ii) evaluated teaching innovations across the broadly defined Earth & space sciences education, including the disciplines of astronomy, climate education, energy resource science, environmental science, geology, geography, agriculture, meteorology, planetary sciences, and oceanography education. The publishing model adopted for this new journal is open-access and articles appear online in GoogleScholar, ERIC, and are searchable in catalogs of 440,000 libraries that index online journals of its type. Rather than paid for by library subscriptions or by society membership dues, the annual budget is covered by page-charges paid by individual authors, their institutions, grants or donors: This approach is common in scientific journals, but is relatively uncommon in education journals. Authors retain their own copyright. The journal is owned by the Clute Institute of Denver, which owns and operates 17 scholarly journals and currently edited by former American Astronomical Society Education Officer Tim Slater, who is an endowed professor at the University of Wyoming and

  18. Applied Historical Astronomy

    Stephenson, F. Richard

    2014-01-01

    F. Richard Stephenson has spent most of his research career -- spanning more than 45 years -- studying various aspects of Applied Historical Astronomy. The aim of this interdisciplinary subject is the application of historical astronomical records to the investigation of problems in modern astronomy and geophysics. Stephenson has almost exclusively concentrated on pre-telescopic records, especially those preserved from ancient and medieval times -- the earliest reliable observations dating from around 700 BC. The records which have mainly interested him are of eclipses (both solar and lunar), supernovae, sunspots and aurorae, and Halley's Comet. The main sources of early astronomical data are fourfold: records from ancient and medieval East Asia (China, together with Korea and Japan); ancient Babylon; ancient and medieval Europe; and the medieval Arab world. A feature of Stephenson's research is the direct consultation of early astronomical texts in their original language -- either working unaided or with the help of colleagues. He has also developed a variety of techniques to help interpret the various observations. Most pre-telescopic observations are very crude by present-day standards. In addition, early motives for skywatching were more often astrological rather than scientific. Despite these drawbacks, ancient and medieval astronomical records have two remarkable advantages over modern data. Firstly, they can enable the investigation of long-term trends (e.g. in the terrestrial rate of rotation), which in the relatively short period covered by telescopic observations are obscured by short-term fluctuations. Secondly, over the lengthy time-scale which they cover, significant numbers of very rare events (such as Galactic supernovae) were reported, which have few -- if any-- counterparts in the telescopic record. In his various researches, Stephenson has mainly focused his attention on two specific topics. These are: (i) long-term changes in the Earth's rate of

    Decades of efforts made by Chinese astronomers have established some basic facilities for astronomy observations, such as the 2.16-m optical telescope, the solar magnetic-field telescope, the 13.7-m millimeter-wave radio telescope etc. One mega-science project, the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), intended for astronomical and astrophysical studies requiring wide fields and large samples, has been initiated and funded. To concentrate the efforts on mega-science projects, to operate and open the national astronomical facilities in a more effective way, and to foster the best astronomers and research groups, the National Astronomical Observatories (NAOs) has been coordinated and organizated. Four research centers, jointly sponsored by observatories of the Chinese Academy of Sciences and universities, have been established. Nine principal research fields have received enhanced support at NAOs. They are: large-scale structure of universe, formation and evolution of galaxies, high-energy and cataclysmic processes in astrophysics, star formation and evolution, solar magnetic activity and heliogeospace environment, astrogeodynamics, dynamics of celestial bodies in the solar system and artificial bodies, space-astronomy technology, and new astronomical techniques and methods.

  20. Challenges in Astronomy Education

    2010-11-01

    Astronomy is an attractive subject for education. It deals with fascination of the unknown and the unreachable, yet is uses tools, concepts and insights from various fundamental sciences such as mathematics, physics, chemistry, biology. Because of this it can be well used for introducing sciences to young people and to raise their interest in further studies in that direction. It is also an interesting subject for teaching as its different aspects (observation techniques, theory, data sampling and analysis, modelling,?) offer various didactical approaches towards different levels of pupils, students and different backgrounds. And it gives great opportunities to teach and demonstrate the essence of scientific research, through tutorials and projects. In this paper we discuss some of the challenges education in general, and astronomy in particular, faces in the coming decades, given the major geophysical and technological changes that can be deducted from our present knowledge. This defines a general, but very important background in terms of educational needs at various levels, and in geographical distribution of future efforts of the astronomical community. Special emphasis will be given to creative approaches to teaching, to strategies that are successful (such as the use of tutorials with element from computer games), and to initiatives complementary to the regular educational system. The programs developed by the IAU will be briefly highlighted.

    Syria has been involved in the field of astronomy since 1997, when Prof. F.R. QUERCI, France, visited Syria and made a presentation on the International NORT project; (NORT: the Network of Oriental Robotic Telescope), which was a selected project of the sixth United Nations/ European Space Agency Workshop on Basic Space Science (document no. A/AC.105/657 dated 13/12/1996). NORT aims to establish a robotic telescope network on high mountain peaks around the Tropic of Cancer, from Morocco in the west to the desert of China in the east. The purposes for establishing this network are technical and educational. The General Organization of Remote Sensing (GORS) has carried out a pilot study using remote sensing techniques and has selected four sites in order to determine the best location for the astronomical observatory the within NORT programme. Following this project, GORS decided to establish an office for astronomical studies, one of the earliest works of GORS in astronomy was an initiative to establish a planetarium within the GORS campus, to accommodate approximately 120 observers. A contest to choose the best planetarium design, for the Arab World, took place at GORS.

    1982-01-01

    Radio techniques were the nrst to lead astronomy away from the quiescent and limited Universe revealed by traditional observations at optical wave­ lengths. In the earliest days of radio astronomy, a handful of radio physicists and engineers made one startling discovery after another as they opened up the radio sky. With this collection of classic papers and the extensive intro­ ductory material, the reader can experience these exciting discoveries, as well as understand the developing techniques and follow the motivations which prompted the various lines of inquiry. For instance he or she will follow in detail the several attempts to detect radio waves from the sun at the turn of the century; the unravelling by Jansky of a "steady hiss type static"; the incredible story of Reber who built a 9 meter dish in his backyard in 1937 and then mapped the Milky Way; the vital discoveries by Hey and colleagues of radio bursts from the Sun and of a discrete source in the constellation of Cygnus; the development of re...

    Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric Dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. Recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.

    A review is given on archaeoastronomy in Armenia and astronomical knowledge reflected in the Armenian culture. Astronomy in Armenia was popular since ancient times and Armenia is rich in its astronomical heritage, such as the names of the constellations, ancient observatories, Armenian rock art (numerous petroglyphs of astronomical content), ancient and medieval Armenian calendars, astronomical terms and names used in Armenian language since II-I millennia B.C., records of astronomical events by ancient Armenians (e.g. Halley's comet in 87 B.C., supernovae explosion in 1054), the astronomical heritage of the Armenian medieval great thinker Anania Shirakatsi's (612-685), medieval sky maps and astronomical devices by Ghukas (Luca) Vanandetsi (XVII-XVIII centuries) and Mkhitar Sebastatsi (1676-1749), etc. For systemization and further regular studies, we have created a webpage devoted to Armenian archaeoastronomical matters at Armenian Astronomical Society (ArAS) website. Issues on astronomy in culture include astronomy in ancient Armenian cultures, ethnoastronomy, astronomy in Armenian religion and mythology, astronomy and astrology, astronomy in folklore and poetry, astronomy in arts, astrolinguistics and astroheraldry. A similar webpage for Astronomy in Armenian Culture is being created at ArAS website and a permanent section "Archaeoastronomy and Astronomy in Culture" has been created in ArAS Electronic Newsletter. Several meetings on this topic have been organized in Armenia during 2007-2014, including the archaeoastronomical meetings in 2012 and 2014, and a number of books have been published. Several institutions are related to these studies coordinated by Byurakan Astrophysical Observatory (BAO) and researchers from the fields of astronomy, history, archaeology, literature, linguistics, etc. are involved.

    The modification of aerosol optical properties due to interaction with fog is examined from measurements made by sun/sky radiometers at several AERONET sites. Retrieved total column volume size distributions for cases identified as aerosol modified by fog often show very a large 'middle mode' submicron radius (~0.4 to 0.5 microns), which is typically seen as a component of a bimodal sub-micron distribution. These middle mode sized particles are often called cloud-processed or residual aerosol. This bimodal accumulation mode distribution may be due to one mode (the larger one) from fog-processed aerosol and the other from interstitial aerosol, or possibly from two different aerosol species (differing chemical composition) with differing hygroscopic growth factors. The size of the fine mode particles from AERONET retrieved for these cases exceeds the size of sub-micron sized particles retrieved for nearly all other aerosol types, suggesting significant modification of aerosols within the fog or cloud environment. In-situ measured aerosol size distributions made during other fog events are compared to the AERONET retrievals, and show close agreement in the residual mode particle size. Almucantar retrievals are analyzed from the Kanpur site in the Indo-Gangetic Plain in India (fog in January), Beijing (fog in winter), Fresno, CA in the San Joaquin Valley (fog in winter), South Korea (Yellow Sea fog in spring), Arica on the northern coast of Chile (stratocumulus), and several other sites with aerosol observations made after fog dissipated. Additionally, several major air pollution events are discussed where extremely high aerosol concentrations were measured at the surface and during which fog also occurred, resulting in the detection very large fine mode aerosols (residual mode) from AERONET retrievals in some of these events. Low wind speeds that occurred during these events were conducive to both pollutant accumulation and also fog formation. The presence of fog then

    The Astronomy Genealogy Project, to be known as AstroGen, will list as many as possible of the world's astronomers with their academic parents (aka thesis advisors) and enable the reader to trace both academic ancestors and descendants. It will be very similar to the highly successful Mathematics Genealogy Project (MGP), available at http://genealogy.math.ndsu.nodak.edu. The MGP, which has been in operation since 1996, now contains the names of about 170,000 "mathematicians." These include many physicists and astronomers, as well as practitioners of related sciences. Mitchel Keller, the director of the MGP, has generously shared the software used in that project, and the American Astronomical Society (AAS) will host AstroGen, a project of the Historical Astronomy Division, on its website. We expect to start seeking entries soon, depending on the availability of computational assistance from the AAS IT department. We are seeking volunteers to help run the project. If you are interested, please contact me at joe.tenn@sonoma.edu.

  9. Astronomy books in Spanish

    Science.gov (United States)

    Fierro, Julieta

    Great cultures have created language. They have discovered its strength among other reasons for education. For a long time the Bible was one of the few books available in western culture, its influence is beyond any doubt. Many developing nations have no science books in their mother tongue. They might carry a few translations but these do not convey the local culture so it is harder for students to grasp the concepts and to build on what they know. Books, even if they are extremely simple, should be written in local languages because that will facilitate the conveying of knowledge and the creation of scientific culture. In the books examples that pertain to every day local life must be given, in particular examples that have to do with women. Women play a central role in developing nations by child bearing; if they become literate they will influence enormously the quality of their children's education, in particular their science comprehension. In Mexico a collection that includes astronomy books has recently been edited by the National Council for Culture and Arts. The books are small and light, which encourages middle-school students to carry them around and read them while traveling in public transportation, such as the subway. Every other page is a new subject, that carries illustrations, abstracts and conclusions. The astronomy books are on search for extraterrestrial life, the stars and the universe. These books are distributed nation-wide and are inexpensive. They have been written by Mexican astronomers.

  10. A Project of a Center for Astronomy Popularization

    Science.gov (United States)

    Bravo-Alfaro, Hector

    At the Astronomy Department of Universidad de Guanajuato 400 km NW of Mexico City eight professional astronomers do research and undergraduate level teaching. In 2000 the facilities of a rudimentary observatory on the roof of the main building of the University were formally assigned to our Department. The site built in the late 1970s includes a 16-cm refractor in a dome and a classroom with capacity for 50 people. The refractor had been out of use for about twelve years. In general maintenance was inexistent and no up grade program had been considered at the time we took the site in charge. Since then with two portable 8-inch telescopes we organize astronomical observations for the general public specially scholars. However many repairs remain to be done of the building and refractor. So far we proposed a project to establish a Center for Popularization of Astronomy to get funds from the Regional Science Council with the aim to carry out the following activities: 1) Permanent program of astronomical observations for a wide audience. 2) Regular talks to the public in different science domains. 3) Summer schools in Astronomy for elementary and high-school teachers. 4) Foundation of an amateur society of astronomy.

    Bring telescope to where the people are! Music and Astronomy Under the Stars (MAUS) is a NASA-funded as astronomy outreach program at community parks and music festivals (1000 - 25,000 people/event). While there have been many astronomy outreach activities and telescope observations at sidewalks and parks, this program targets a different audience - music lovers who are attending concerts in community parks or festivals. These music lovers who may not have visited science museums, planetariums, or star parties are exposed to telescope observations and astronomy information with no additional travel costs. MAUS includes solar observing, telescope observations including a live imaging system, an astronomical video, astronomy banners/posters, and hands-on activities. MAUS increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. Since 2009 over 50,000 people have participated in these outreach activities including a significant number of families and young girls. In addition to concerts in local Long Island parks, there were MUAS events at Tanglewood (summer home of the Boston Symphony Orchestra), Jazz in Central Park, and Astronomy Night on the National Mall (co-sponsored by the White House Office of Science and Technology Policy). In 2011 MUAS will be expanded to include Ravinia (summer home of the Chicago Symphony Orchestra), the Newport Folk Festival, and the Bethel Woods Center for the Arts (site of the 1969 Woodstock festival). According to our survey results, music lovers became more informed about astronomy. Expanding Hofstra University's successful outreach programs, I propose the creation of a National Halloween Stars event targeting children and a National Super Bowl Star Party targeting girls, women, and the 2/3 of Americans who do not watch the Super Bowl. This can be combined with astronomers or amateur astronomers bringing telescopes to Super Bowl parties for football fans to stargaze during

    large number of teachers, amateur astronomers and others interested in this field of science. The Astronomy On-line concept is that of a well-structured marketplace with a number of different shops which cater to the participants with a great variety of interesting and educational activities. These range from the availability of useful links to educational and scientific Web sites all around the world, collaborative projects where many participants in different countries work together to achieve an astronomical result and, not the least, the possibility to submit observing programmes to a dozen telescopes at 10 major observatories, including La Silla in Chile. In the early phases of Astronomy On-line , coordinated observations were performed of a lunar eclipse on 27 September and a partial solar eclipse on 12 October. Both events attracted many hundreds of observers from groups in almost all European countries and provisional reports have already been published on the Web. Many beautiful photographs and interesting reports about the activities of the individual groups are also available at their special Web sites. The Hot Week will last from Monday to Friday, 18-22 November and the time interval from 15:00-21:00 UT (16:00 - 22:00 Central European Time) will be the busiest. During this period, a variety of activities will take place. For instance, the groups will have the opportunity to contact professional astronomers at many observatories. They will also be invited to follow the other developments, e.g. the astronomical observations. The resulting images will immediately be made available on the Web. There will also be a Final Event involving all the groups.

    Astronomy and related fields are at the forefront of science and technology; answering fundamental questions and driving innovation. Although blue-skies research like astronomy rarely contributes directly with tangible outcomes on a short time scale, the pursuit of this research requires cutting-edge technology and methods that can on a longer time scale, through their broader application make a difference. A wealth of examples show how the study of astronomy contributes to technology, econom...

  14. Astronomy in the Service of Islam

    King, David A.

    In their assessment of Islamic astronomy, historians have usually been concerned only with that part of the Muslim scientific heritage that was transmitted to the West in the Middle Ages. Yet most Islamic works on astronomy were not transmitted to the West, and they are known today mainly due to the work of orientalists in the nineteenth and twentieth centuries. This is the case of Muslim writings on three aspects of mathematical science that were closely linked with religious observance. This is an overview of those "Islamic aspects of Islamic astronomy".

  15. Exchange of astronomy teaching experiences

    Ros, Rosa M.

    The Working Group of the European Association for Astronomy Education responsible for Teacher Training organises an annual Summer School for teachers under expert guidance. For a week the teachers participating can exchange experiences, increase their knowledge and discuss different ideas and perspectives. In general, the instructors are professional astronomers, professors and teachers from different countries. The papers presented offer very practical activities, paying special attention to didactic aspects, and take the form of general lectures to all 40 participants and workshops to reduced groups of 20 participants. There are also day and night observations, without expensive equipment or complicated procedures, that are easy to set up and based on topics that it is possible to use in the classroom. The Summer Schools promote a scientific astronomical education at all levels of astronomy teaching, reinforce the link between professional astronomers and teachers with experience of teaching astronomy, allow debates among the participants on their pedagogical activities already carried out in their own classroom and help them to organise activities outside it. Astronomy teachers need special training, access to specific research, to new educational materials and methods and the opportunity to exchange experiences. All these things are provided by the Summer School.

  16. Indigenous Astronomies and Progress in Modern Astronomy

    CERN Document Server

    Ruggles, Clive

    2010-01-01

    From an anthropological point of view, the whole concept of a "path of progress" in astronomical discovery is anathema, since it implicitly downgrades other cultural perspectives, such as the many "indigenous cosmologies" that still exist in the modern world. By doing so, one risks provoking those who hold them and-as is most obvious in places such as Hawaii where the two "world-views" come into direct contact-reating avoidable resistance to that very progress. The problem is complicated by the existence of "fringe" and "new-age" views that are increasingly confused with, and even passed off as, indigenous perceptions. In a modern world where widespread public perceptions include many that are unscientific in the broadest sense of the term, I shall argue that there are actually a range of positive benefits for progress in scientific astronomy to be derived from the mutual awareness and comprehension of "genuine" cultural world-views whose goals-in common with those of modern science-are to make sense of the c...

    2013-05-01

    Abstract (2,250 Maximum Characters): The Astronomy Workshop (http://janus.astro.umd.edu) is a collection of interactive online educational tools developed for use by students, educators, professional astronomers, and the general public. The more than 20 tools in the Astronomy Workshop are rated for ease-of-use, and have been extensively tested in large university survey courses as well as more specialized classes for undergraduate majors and graduate students. Here we briefly describe the tools most relevant for the Professional Dynamical Astronomer. Solar Systems Visualizer: The orbital motions of planets, moons, and asteroids in the Solar System as well as many of the planets in exoplanetary systems are animated at their correct relative speeds in accurate to-scale drawings. Zoom in from the chaotic outer satellite systems of the giant planets all the way to their innermost ring systems. Orbital Integrators: Determine the orbital evolution of your initial conditions for a number of different scenarios including motions subject to general central forces, the classic three-body problem, and satellites of planets and exoplanets. Zero velocity curves are calculated and automatically included on relevant plots. Orbital Elements: Convert quickly and easily between state vectors and orbital elements with Changing the Elements. Use other routines to visualize your three-dimensional orbit and to convert between the different commonly used sets of orbital elements including the true, mean, and eccentric anomalies. Solar System Calculators: These tools calculate a user-defined mathematical expression simultaneously for all of the Solar System's planets (Planetary Calculator) or moons (Satellite Calculator). Key physical and orbital data are automatically accessed as needed.

    Smith, Robert C

    1995-01-01

    Combining a critical account of observational methods (telescopes and instrumentation) with a lucid description of the Universe, including stars, galaxies and cosmology, Smith provides a comprehensive introduction to the whole of modern astrophysics beyond the solar system. The first half describes the techniques used by astronomers to observe the Universe: optical telescopes and instruments are discussed in detail, but observations at all wavelengths are covered, from radio to gamma-rays. After a short interlude describing the appearance of the sky at all wavelengths, the role of positional astronomy is highlighted. In the second half, a clear description is given of the contents of the Universe, including accounts of stellar evolution and cosmological models. Fully illustrated throughout, with exercises given in each chapter, this textbook provides a thorough introduction to astrophysics for all physics undergraduates, and a valuable background for physics graduates turning to research in astronomy.

    This study was conducted in Turkey within an interdisciplinary project called "From a windowless home to a skyscraper: Let's build a home". It was realized through collaboration between a public university and a private high school. Researchers from Physics Education Department and volunteer teachers from high school, each studying on a different discipline, and volunteer high school students, all from an urban area of the country, conducted the project in a rural small town with resident secondary school students. It was implemented on the basis of history, through the use of different fields such as science, mathematics, geography, art, handcraft, architecture, engineering and astronomy in August 2008. The purpose of this study was to present the effect of the astronomical activities involved in the project. These implementations constructed a scientific and social base for the framework of astronomical activities of IYA2009, including building an amateur observatory. Since today's people are not so much acquainted with the issues of space and astronomy as much as the people of Antiquity, we attached special importance to the efforts in this field. The project, proceeded by a preparatory and informative period, involved night sky observation, initially with naked eye, followed by observation through telescope. Not only the students but also countless people, old or young, participated in our work in the field of astronomy. It provided a chance for all the people participating in or connected to the project to discover the sky. Astronomical activities aroused curiosity among students and the community and made a difference by inducing an awareness of the sky. The participants of the study had completely different social and cultural backgrounds, and this study removed all these differences bringing them together under the overarching astronomical and historical aspect. Moreover the community revealed all the characteristics that constitute a learning community.

    This study presents results of a survey conducted at the Federal Institution of Education, Science and Technology in the North of Minas Gerais (IFNMG), and aimed to investigate the potentialities of the use of interactive materials in the teaching of astronomy. An advanced training course with involved learning activities about basic concepts of astronomy was offered to thirty-two Licenciate students in Physics, Mathematics and Biological Science. The following steps were to be taken: i) analysis of the pedagogical projects (PPC) of the licenciates at the IFNMG, research locus of its Campus Januária; ii) analysis of students' preconceptions about astronomy and digital technologies, identified by the application of an initial questionnaire; iii) preparation of the course taking into account the students' previous knowledge; iv) application of the education proposal developed under part-time presence modality, using various interactive tools; v) application and analysis of the final questionnaire. The test was conducted with the qualitative and quantitative methodology, combined with a content analysis. The results indicated that in the IFNMG only the licenciate-course in physics includes astronomy content diluted in various subjects of the curriculum; the rates of students prior knowledge in relation to astronomy was low; an evidence of meaningful learning of the concepts related to astronomy, and of viability of resource use involving digital technologies in the Teaching of astronomy, which may contribute to the broadening of methodological options of future teachers and meet their training needs.

    2006-08-01

    Astronomy is, by definition, the sum of the material and spiritual values created by mankind and of the institutions necessary to communicate these values. Consequently, astronomy belongs to the culture of each society and its scientific progress does nothing but underline its role in culture. It is interesting that there is even a European society which bears this name "Astronomy for Culture" (SEAC). Its main goal is "the study of calendric and astronomical aspects of culture". Owning ancient evidence of astronomical knowledge, dating from the dawn of the first millennium, Romania is interested in this topic. But Astronomy has a much deeper role in culture and civilization. There are many aspects that deserve to be discussed. Examples? The progress of astronomy in a certain society, in connection with its evolution; the place held by the astronomy in literature and, generally, in art; the role of the SF in the epoch of super-mediatization; astronomy and belief; astronomy and astrology in the modern society, and so forth. These are problems that can be of interest for IAU, but the most important one could be her educational role, in the formation of the culture of the new generation, in the education of the population for the protection of our planet, in the ensuring of a high level of spiritual development of the society in the present epoch.

    Joseph Henry (1797-1878) is best known for his work in electromagnetism and as the first secretary of the Smithsonian Institution. But he was also a pioneer solar physicist, an early advocate of US participation in astrophysics, and a facilitator of international cooperation in astronomy. This paper will briefly trace his role in the development of the US astronomical community from the time he taught astronomy at Princeton in the 1830s through his death, focusing on failed efforts to persuade US astronomers and patrons of astronomy that the best path for US astronomy should be astrophysics. He thought that the US could make a more significant contribution to astronomy science by striking out on a less travelled path rather than competing with the established European observatories.

    In the last two years the National Observatory at Tonantzintla Puebla, México (OAN Tonantzintla), has been undergoing several facilities upgrades in order to bring to the observatory suitable conditions to operate as a modern Observational Astronomy Teaching Laboratory. In this paper, we present the management, requirement definition and project advances. We made a quantitative diagnosis about of the functionality of the Tonantzintla Observatory (mainly based in the 1m f/15 telescope) to take aim to educational objectives. Through this project we are taking the steps to correct, to actualize and to optimize the observatory astronomical instrumentation according to modern techniques of observation. We present the design and the first actions in order to get a better and efficient use of the main astronomical instrumentation, as well as, the telescope itself, for the undergraduate, postgraduate levels Observacional Astronomy students and outreach publics programs for elementary school. The project includes the development of software and hardware components based in as a common framework for the project management. The Observatory is located at 150 km away from the headquarters at the Instituto de Astronomía, Universidad Nacional Autónoma de México (IAUNAM), and one of the goals is use this infrastructure for a Remote Observatory System.

    The authors discusse the insuccess of the observation of the Total Eclipse of the Moon from 10 december 2011 in Romania and relate them with meteoconditions. Only a very short part of the last penumbral phase was observed, while the inital part and the totality was not observed due to very dense clouds. The change in color and brightness during this phase was signaled. Meanwhile, there is an area of science where clouds are of great use and interest. This area is Atmospheric optics, while the science which study clouds is meteorology. Clouds in combination with Solar and Moon light could give rise to a variety of strange, rare and unobvious phenomena in the atmosphere (sky), sometimes confused with Unidentified Flying Objects (UFO). The importance of meteorology for astronomy and atmospheric optics is underlined and an invitation to astronomers to use unfavourable days for athmospheric observations was sent. The web address of the site by Les Cowley, designed for atmospheric optics phenomena is contained in the text of the entry.

    2015-01-01

    Astronomy data management refers to all actions taken upon data over the course of the entire research process. It includes activities involving the collection, organization, analysis, release, storage, archiving, preservation, and curation of research data. Astronomers have cultivated data management tools, infrastructures, and local practices to ensure the use and future reuse of their data. However, new sky surveys will soon amass petabytes of data requiring new data management strategies.The goal of this dissertation, to be completed in 2015, is to identify and understand data management practices and the infrastructure and expertise required to support best practices. This will benefit the astronomy community in efforts toward an integrated scholarly communication framework.This dissertation employs qualitative, social science research methods (including interviews, observations, and document analysis) to conduct case studies of data management practices, covering the entire data lifecycle, amongst three populations: Sloan Digital Sky Survey (SDSS) collaboration team members; Individual and small-group users of SDSS data; and Large Synoptic Survey Telescope (LSST) collaboration team members. I have been observing the collection, release, and archiving of data by the SDSS collaboration, the data practices of individuals and small groups using SDSS data in journal articles, and the LSST collaboration's planning and building of infrastructure to produce data.Preliminary results demonstrate that current data management practices in astronomy are complex, situational, and heterogeneous. Astronomers often have different management repertoires for working on sky surveys and for their own data collections, varying their data practices as they move between projects. The multitude of practices complicates coordinated efforts to maintain data.While astronomy expertise proves critical to managing astronomy data in the short, medium, and long term, the larger astronomy

    How do we encourage more students to pursue science, technology, engineering and mathematics (STEM) careers? We are using astronomy to engage rural, at-risk and/or Native Hawaiian students living on other islands with a passion for science. Our workshops on Molokai, Maui, and the Big Island of Hawaii have been unique by including both students and teachers as learners. Participants, as young as 5th-graders, are exposed to the physics principles underlying basic astronomy concepts, including laws of motion, gravitation, orbits, optics, and the EM spectrum. The workshop builds toward research skills such as blink-comparison, astrometry, and photometry of CCD images using commercially available software. Ultimately, students and teachers have an opportunity to use the professional grade 2.0-m LCOGT telescope located atop Haleakala on Maui for observational research. Lessons learned and future plans for a 2007 summer workshop will be shared. This program is supported by a NASA IDEAS EPO Grant.

    We review the relatively new, internet-enabled, and rapidly-evolving field of citizen science, focusing on research projects in stellar, extragalactic and solar system astronomy that have benefited from the participation of members of the public, often in large numbers. We find these volunteers making contributions to astronomy in a variety of ways: making and analyzing new observations, visually classifying features in images and light curves, exploring models constrained by astronomical datasets, and initiating new scientific enquiries. The most productive citizen astronomy projects involve close collaboration between the professionals and amateurs involved, and occupy scientific niches not easily filled by great observatories or machine learning methods: citizen astronomers are most strongly motivated by being of service to science. In the coming years we expect participation and productivity in citizen astronomy to increase, as survey datasets get larger and citizen science platforms become more efficient...

    The New Mexico State University (NMSU) Society of Astronomy Students (SAS) is an undergraduate organization centered on students’ passions for learning and sharing knowledge about the field of astronomy. The SAS strives to become one of the most active clubs on the NMSU campus by their involvement in both astronomy and non-astronomy related public outreach and community service events. NMSU is located in Las Cruces, NM, where Clyde Tombaugh made great contributions both to the field of astronomy and to our local community. He was able to spark the community's interest in astronomy and science in general; this is an aspect of his career that the SAS strives to emulate. To do this, the SAS participates in community outreach events with the goal of stimulating curiosity and providing opportunities for the public to observe and understand exciting phenomenon occurring in our universe. With help from the NMSU Astronomy Department, the SAS is able to volunteer alongside the Astronomy Graduate Student Organization (AGSO) at events for people of all ages. Working jointly with the AGSO allows us to be mentored by the very students who were in our shoes not long ago; they educate us about the wonders of the universe, just as we wish to educate the community. This provides an enlightening and enriching environment for both club and community members. The NMSU Astronomy Department hosts events for the entire community, such as observing nights held at Tombaugh Observatory — which SAS members attend and help advertise — where community members learn about and view objects in the night sky through telescopes. SAS members assist with field trips where local middle and elementary school students attend presentations and participate in astronomy-related activities on the NMSU campus. These hands-on activities are presented in an understandable way, and are meant to increase appreciation for all of the exciting subjects our universe has to offer. Other outreach events include

    2014-01-01

      Like everyone else, most amateur astronomers live busy lives. After a long day, the last thing you want as an observer is to have to lug out a large telescope and spend an hour getting it ready before it can be used. Maybe you are going somewhere sure to have dark skies, but you don’t necessarily want astronomy to dominate the trip. Or you are not quite committed to owning a large telescope, but curious enough to see what a smaller, portable setup can accomplish. These are times when a small “grab ’n’ go” telescope, or even a pair of binoculars, is the ideal in­strument. And this book can guide you in choosing and best utilizing that equipment.   What makes a telescope fall into the “grab ’n’ go” category? That’s easy – speed of setting up, ease of use, and above all, portability. This ambitious text is dedicated to those who love to or – because of their limited time – must observe the sky at a moment’s notice. Whether observing from the comfort of a backyard or while on busi...

    2001-12-01

    The School of Galactic Radio Astronomy (SGRA) takes its name from the source SGR-A, the center of the Milky Way Galaxy. SGRA is based at the Pisgah Astronomical Research Institute (PARI) as an experience-based school room for use by middle and high school teachers and their students. Their scientific educational experience at SGRA relies on Internet access to PARI's remote-controlled 4.6-m radio telescope which is equipped with a 1420 MHz receiver. The 1420 MHz signal may either be recorded as a spectrum over a 4 MHz bandpass, or mapped over extended regions. Teachers, classes, and Independent Study students access the 4.6-m radio telescope via the SGRA webpage. The SGRA webpage has four components: Radio Astronomy Basics, Observing, Guides, and Logbook. The Radio Astronomy Basics section summarizes the concepts of electromagnetic waves, detection of electromagnetic waves, sources of astronomical radio waves, and how astronomers use radio telescopes. The Observing section is the link to controlling the radio telescope and receiver. The Observing page is designed in the same way a control room at an observatory is designed. Controls include options of source selection, coordinate entry, slew, set, and guide selection, and tracking. Also within the Observing section is the curriculum which presents eight modules based on relevant radio astronomy topics and objects. The Guides webpage contains atlases of the astronomical sky, catalogs, examples of observing sessions, and data reduction software that can be downloaded for analysis offline. The LOGBOOK page is primarily a guestbook, and evaluation form. We acknowledge support from the Space Telescope Science Institute IDEAS Program, and the South Carolina State University PAIR Program.

    2015-01-01

    Students today are expected to have access to computers and the Internet. Students young and old, in school and out of school, are interested in learning about astronomy, and have computers to use for this. Teach Astronomy is a website with a comprehensive digital astronomy textbook freely available to students and educators. In addition to the textbook, there are astronomy Wikipedia articles, image archives from Astronomy Picture of the Day and AstroPix, and video lectures covering all topics of astronomy. Teach Astronomy has a unique search tool called the wikimap that can be used to search through all of the resources on the site. Astronomy: State of the Art (ASOTA) is a massive, open, online course (MOOC). Over 18,000 students have enrolled over the past year and half. This MOOC has been presented in various forms. First, only to students on the web, with content released weekly on host site Udemy. Then to university students who met formally in the classroom for educational activities, but were also expected to watch lectures online on their own time. Presently, it is available online for students to go at their own pace. In the future it will be available in an extended format on a new host site, Coursera. ASOTA instructors use social media to interact with students. Students ask questions via the course host site, Udemy. Live question and answer sessions are conducted using Google Hangouts on Air, and interesting and relevant astronomy news, or supplementary educational content is shared via the ASOTA Facebook page. Teaching on the Internet may seem impersonal and impractical, but by learning to use all of these tools, instructors have the ability to interact with students, and keep them engaged.

  1. Astronomy and culture

    2009-01-01

    While astronomy is a burgeoning science, with tremendous increases in knowledge every year, it also has a tremendous past, one that has altered humanity's understanding of our place in the universe. The impact of astronomy on culture - whether through myths and stories, or through challenges to the intellectual status quo - is incalculable. This volume in the Greenwood Guides to the Universe series examines how human cultures, in all regions and time periods, have tried to make sense of the wonders of the universe. Astronomy and Culture shows students how people throughout time have struggled

    The project has progressed successfully during this period of performance. The highlights of the Gamma Ray Astronomy teams efforts are: (1) Support daily BATSE data operations, including receipt, archival and dissemination of data, quick-look science analysis, rapid gamma-ray burst and transient monitoring and response efforts, instrument state-of-health monitoring, and instrument commanding and configuration; (2) On-going scientific analysis, including production and maintenance of gamma-ray burst, pulsed source and occultation source catalogs, gamma-ray burst spectroscopy, studies of the properties of pulsars and black holes, and long-term monitoring of hard x-ray sources; (3) Maintenance and continuous improvement of BATSE instrument response and calibration data bases; (4) Investigation of the use of solid state detectors for eventual application and instrument to perform all sky monitoring of X-Ray and Gamma sources with high sensitivity; and (5) Support of BATSE outreach activities, including seminars, colloquia and World Wide Web pages. The highlights of this efforts can be summarized in the publications and presentation list.

  3. Astronomy, Astrology, and Medicine

    Science.gov (United States)

    Greenbaum, Dorian Gieseler

    Astronomy and astrology were combined with medicine for thousands of years. Beginning in Mesopotamia in the second millennium BCE and continuing into the eighteenth century, medical practitioners used astronomy/astrology as an important part of diagnosis and prescription. Throughout this time frame, scientists cited the similarities between medicine and astrology, in addition to combining the two in practice. Hippocrates and Galen based medical theories on the relationship between heavenly bodies and human bodies. In an enduring cultural phenomenon, parts of the body as well as diseases were linked to zodiac signs and planets. In Renaissance universities, astronomy and astrology were studied by students of medicine. History records a long tradition of astrologer-physicians. This chapter covers the topic of astronomy, astrology, and medicine from the Old Babylonian period to the Enlightenment.

  4. Islands of Astronomy

    2009-05-01

    Full Text Available A global review of islands and their connections with astronomy throughout history up to the contemporary times suggests eight compelling, distinct yet interlocking reasons why islands have been and remain so important to astronomy and astronomers. Islands constitute favourable locations for various types of astronomy-related activities: from tracking satellites and monitoring significant celestial events, to providing exceptional locations to jurisdictions with mandated dark and unpolluted skies. They appeal for their favourable longitude and (especially southern latitude, as well as for their disposition towards the conditions that the scientific community may expect in an ideal world: relatively clear viewing conditions from a secure, self-contained platform that is, however, endowed with connectivity. This article is written as a contribution to the International Year of Astronomy (2009.

    The present volume gathers together the talks presented at the second colloquium on the Future Professional Communication in Astronomy (FPCAII), held at the Harvard-Smithsonian Center for Astrophysics (Cambridge, MA) on 13-14 April 2010. This meeting provided a forum for editors, publishers, scientists, librarians and officers of learned societies to discuss the future of the field. The program included talks from leading researchers and practitioners and drew a crowd of approximately 50 attendees from 10 countries. These proceedings contain contributions from invited and contributed talks from leaders in the field, touching on a number of topics. Among them: The role of disciplinary repositories such as ADS and arXiv in astronomy and the physical sciences; Current status and future of Open Access Publishing models and their impact on astronomy and astrophysics publishing; Emerging trends in scientific article publishing: semantic annotations, multimedia content, links to data products hosted by astrophysics archives; Novel approaches to the evaluation of facilities and projects based on bibliometric indicators; Impact of Government mandates, Privacy laws, and Intellectual Property Rights on the evolving digital publishing environment in astronomy; Communicating astronomy to the public: the experience of the International Year of Astronomy 2009.

  6. Astronomy and Mathematics Education

    Science.gov (United States)

    Ros, Rosa M.

    There are many European countries where Astronomy does not appear as a specific course on the secondary school. In these cases Astronomy content can be introduced by means of other subjects. There are some astronomical topics within the subject of Physics but this talk concerns introducing Astronomy in Mathematics classes. Teaching Astronomy through Mathematics would result in more exposure than through Physics as Mathematics is more prevalent in the curriculum. Generally it is not easy to motivate students in Mathematics but they are motivated to find out more about the universe and Astronomy current events than appears in the media. This situation can be an excellent introduction to several mathematics topics. The teachers in secondary and high school can use this idea in order to present more attractive mathematics courses. In particular some different examples will be offered regarding * Angles and spherical coordinates considering star traces * Logarithms and visual magnitudes * Plane trigonometry related orbital movements * Spherical trigonometry in connection with ecliptic obliquity * Conic curves related to sundial at several latitudes Some students do not enjoy studying Mathematics but they can be attracted by practical situations using Applied Mathematics: Astronomy is always very attractive to teenagers.

    2010-01-01

    We present one of the new generations of observatories, the Stratospheric Observatory For Infrared Astronomy (SOFIA). This is an airborne observatory consisting of a 2.7-m telescope mounted on a modified Boeing B747-SP airplane. Flying at an up to 45,000 ft (14 km) altitude, SOFIA will observe above more than 99 percent of the Earth's atmospheric water vapor allowing observations in the normally obscured far-infrared. We outline the observatory capabilities and goals. The first-generation science instruments flying on board SOFIA and their main astronomical goals are also presented.

    2014-01-01

    We present here an energetic grass-roots outreach program run entirely by undergraduate physics and astronomy majors at James Madison University. Our "Team Awestronomy" takes Astronomy out to the Market, literally. Once a month, for eight months during the academic year, the group sets up a “scientific corner” at the Harrisonburg Farmers Market, offering people the chance to meet with astrophysicists (in the making) and discuss science. Our group members wear t-shirts with simple messages like “Ask me about the Sun,” “...about Black Holes and Mega-Masers” or “...about Big Bang” that initiate the dialog. We help our audience with observations of solar activity through our department’s Coronado telescope equipped with a safe H-alpha filter, sunspotters, and the incredibly simple yet durable and accurate handheld (Project Star) spectrometers, and invite them to the free Saturday Planetarium shows and the star parties hosted by our department on the JMU campus. The team is also prepared with a suite of fun activities aimed particularly at K-5 kids, e.g., building (and eating, after investigating out-gassing properties of) ”dirty comets,” making craters (in pans with flour or sand) and testing how different types of impactors (pebbles, ping-pong balls or even crumpled aluminum foil) affect crater formation, and demonstrations of shock wave created in supernova explosions. The main goals of this outreach program are: 1) to illustrate to people of all ages that science is a fun, creative, and exciting process; 2) to empower people to be curious and to ask questions; 3) to demonstrate that science is a viable career path chosen by many diverse individuals; and 4) to nurture a sense of wonder and awe for the Universe. While this outreach program is aimed at a very general audience, of an extremely wide range, we expect to produce a significant impact on K-12 students in general and in particular on the home-schooled kids. There is a relatively high

    Farmanyan, S. V.; Mickaelian, A. M.

    2016-12-01

    Cultural Astronomy is the reflection of sky events in various fields of nations' culture. In foreign literature, this field is also called "Astronomy in Culture" or "Astronomy and Culture". Cultural astronomy is the set of interdisciplinary fields studying the astronomical systems of current or ancient societies and cultures. It is manifested in Religion, Mythology, Folklore, Poetry, Art, Linguistics and other fields. In recent years, considerable attention has been paid to this sphere, particularly international organizations were established, conferences are held and journals are published. Armenia is also rich in cultural astronomy. The present paper focuses on Armenian archaeoastronomy and cultural astronomy, including many creations related to astronomical knowledge; calendars, rock art, mythology, etc. On the other hand, this subject is rather poorly developed in Armenia; there are only individual studies on various related issues (especially many studies related to Anania Shirakatsi) but not coordinated actions to manage this important field of investigation.

  10. Edible Astronomy Demonstrations

    Lubowich, Donald A.

    2007-12-01

    Astronomy demonstrations with edible ingredients are an effective way to increase student interest and knowledge of astronomical concepts. This approach has been successful with all age groups from elementary school through college students - and the students remember these demonstrations after they are presented. In this poster I describe edible demonstrations I have created to simulate the expansion of the universe (using big-bang chocolate chip cookies); differentiation during the formation of the Earth and planets (using chocolate or chocolate milk with marshmallows, cereal, candy pieces or nuts); and radioactivity/radioactive dating (using popcorn). Other possible demonstrations include: plate tectonics (crackers with peanut butter and jelly); convection (miso soup or hot chocolate); mud flows on Mars (melted chocolate poured over angel food cake); formation of the Galactic disk (pizza); formation of spiral arms (coffee with cream); the curvature of Space (Pringles); constellations patterns with chocolate chips and chocolate chip cookies; planet shaped cookies; star shaped cookies with different colored frostings; coffee or chocolate milk measurement of solar radiation; Oreo cookie lunar phases. Sometimes the students eat the results of the astronomical demonstrations. These demonstrations are an effective teaching tool and can be adapted for cultural, culinary, and ethnic differences among the students.

  11. Astronomy adventures and vacations how to get the most out of astronomy in your leisure time

    Treadwell, Timothy

    2017-01-01

    This astronomy travel guide examines the many wonderful opportunities for experiencing the observing hobby. Amateur astronomy is often consigned to observing from home or from a local park, yet it can be much more. Tim Treadwell explores all the possibilities of astronomical and space-related activities that are available on day trips and longer vacations. These activities range from observatory visits and other simple ways to build an astronomy event into a holiday, to full blown specialized astronomy travel. Many trips give the opportunity to visit some of the world’s famous attractions. On most vacations it can be a matter of just taking a day (or night) out of your schedule to fit in an astronomy event, but larger, dedicated pilgrimages are also possible. How to make the most of astronomy potential on a holiday, whether observing on the beach in Hawaii with the Telescope Guy or visiting Star City in Russia, is covered in detail. Go to a star party, explore the national parks or see the northern lights! ...

    2009-01-01

    This white paper offers cautionary observations about the planning and development of new, large radio astronomy instruments. Complexity is a strong cost driver so every effort should be made to assign differing science requirements to different instruments and probably different sites. The appeal of shared resources is generally not realized in practice and can often be counterproductive. Instrument optimization is much more difficult with longer lists of requirements, and the development process is longer and less efficient. More complex instruments are necessarily further behind the technology state of the art because of longer development times. Including technology R&D in the construction phase of projects is a growing trend that leads to higher risks, cost overruns, schedule delays, and project de-scoping. There are no technology breakthroughs just over the horizon that will suddenly bring down the cost of collecting area. Advances come largely through careful attention to detail in the adoption of ...

    Farmanyan, Sona V.; Mickaelian, Areg M.

    2015-08-01

    We present a general overview on Armenian Archaeoastronomy and Astronomy in Culture to mention and summarize some activities and related organizations involved. Armenia is rather rich in archaeoastronomy and culture, including calendars, rock art, mythology, etc. Archaeoastronomical issues in Armenia include: Zodiac Constellations (believed to be introduced for the first time in the Armenian Highland); Ancient Observatories; Armenian Rock Art; Ancient Armenian Calendar and other (medieval) calendars; Astronomical Terms and Names; Records of Astronomical Events by ancient Armenians; Anania Shirakatsi’s (612-685) Astronomical Heritage; Medieval Sky Maps and Astronomical Devices. During the recent years, we have organized a number of meetings, where archaeoastronomy was involved: Joint European and National Astronomy Meeting (JENAM-2007), Special Session #6: “Archaeoastronomy” (2007), ArAS VIII Annual Meeting “Astronomy and Society”, Session “Archaeoastronomy” (2009), Archaeoastronomical meeting “Astronomical Heritage in the National Culture” dedicated to Anania Shirakatsi’s 1400th anniversary (2012), Meeting “Relation of Astronomy to other Sciences, Culture and Society” (RASCS), Sessions“Archaeoastronomy” and “Astronomy in Culture” (2014). Along with Byurakan Astrophysical Observatory (BAO), there are several other institutions related to Archaeoastronomy and Astronomy in Culture: Institute of History, Institute of Archaeology and Ethnography, Institute of Literature, Institute of Language, Matenadaran (Institute of Ancient Manuscripts). We have introduced a section “Archaeoastronomy and Astronomy in Culture” in the newsletter of Armenian Astronomical Society (ArAS). This is to strengthen ArAS activities and to widen our knowledge in this area, to encourage and establish collaborations with other scientists related to these subjects; historians, archaeologists, ethnographers, philologists, linguists, artists and other

    2009-01-01

    The 365 Days of Astronomy Podcast is a community project that brings the voices of the global astronomy community to the public over the Internet. We are publishing 1 podcast per day, 5 to 10 minutes in duration, for all 365 days of 2009. The podcast is made available through an RSS feed. The podcast episodes are recorded and listened to by people around the world. Topics covered include astronomy inspired art and literature, historic discoveries, spacecraft, IYA events as well as interviews and discussions about the science of astronomy. Some podcasts have a specific topic or theme based on The 365 Days of Astronomy Calendar, a daily calendar of astronomical events, themes and ideas created by the IYA. Although all the episodes will have a common intro and outtro that ties into the overall theme, each episode is completely different. Are you willing to contribute to the 365 Days of Astronomy podcast?We are looking for individuals, schools, companies and clubs to provide 5 - 10 minutes of audio for our daily podcast. Our goal is to encourage people to sign up for a particular day (or days) of 2009. We have a calendar of astronomical events to give ideas but the podcasts can be about virtually any astronomical topic. We are seeking a wide range of contributions, from simple concepts or how-tos to more in-depth discussions of complex concepts. We are expecting a wide range of contributions, from simple at-home "first light” podcasts to highly polished and professional recordings. We hope to sign up a wide range of participants including professional astronomers, K-12 classrooms, college students, science bloggers, podcasters and media companies.

    de Macedo, J. A.; Voelzke, M. R.

    2014-08-01

    This study presents results of a survey conducted at the Federal Institution of Education, Science and Technology in the North of Minas Gerais (IFNMG), and aimed to investigate the potential uses of interactive materials in the teaching of astronomy. Despite being part of official documents, proposals included in the curriculum of several states, and having contributed to human and technological development, astronomy is rarely taught adequately in the Brazilian basic education. When it is taught, it is with unsatisfactory results as presented by students and teachers as shown by several studies, such as those carried out by (Voelzke and Gonzaga, 2013). Digital technologies are commonly used by youth, but neglected by the majority of teachers. In this sense, a survey with the aim of pointing out the potential use of digital technologies in teaching astronomy was developed. An advanced course in astronomy was offered for participants with the goal to help them understand astronomical phenomena. The following steps were to be taken: i) analysis of the pedagogical projects (PPC) of the licenciates at the IFNMG, with its Campus Januária as research locus; ii) analysis of students' preconceptions about astronomy and digital technologies, identified by the application of an initial questionnaire; iii) preparation of the course taking into account the students' previous knowledge; iv) application of the education proposal developed under part-time presence modality, using various interactive tools; v) application and analysis of the final questionnaire. The test consisted of thirty-two students of physics, mathematics and biology and was conducted with the qualitative and quantitative methodology, combined with a content analysis. Among other results, it was verified that: (i) In the IFNMG only the licenciate-course in physics includes astronomy content diluted in various subjects of the curriculum; (ii) the analysis of the initial questionnaire showed even that group

    Constantin, Ana-Maria; Goodman, A. A.; Udomprasert, P. S.

    2014-01-01

    This project aims to improve astronomy education at the high school level, and to increase awareness in astronomy for pre-university students, on an international scale. In 2013, the WorldWide Telescope Ambassadors Program began a collaboration with the International Olympiad in Astronomy and Astrophysics (IOAA), which was held in the city of Volos, Greece in August 2013. Now at its VIIth edition, IOAA is the largest annual astronomy competition for high school students, and it consists of one team task and three individual ones - Theoretical, Data Analysis, and Observational. Each of the participating countries (35 in 2013, compared to 21 in 2007) is responsible for selecting up to five representative students for the International round. IOAA is meant to promote future collaborations between these students, and to encourage friendships inside a global scientific community. Ana-Maria Constantin, a current Harvard undergraduate student and a former medalist of IOAA, represented WorldWide Telescope Ambassadors in Greece by giving a talk on the advantages of using WWT as a tool for research and education. As a result, the President and the International Board of the Olympiad have expressed support for including WWT in the competition for future editions. WWTA is working with the Organizing Board for next year’s competition in Romania, to include WWT as a testing tool. This poster will summarize key points from the WWTA presentation in Greece, present ideas for WWT-based activities in future IOAA competitions, and outline plans for new collaborations from representatives of Sri Lanka, Poland, Bangladesh, and Colombia. Given the positive feedback we have received after the presentation in Greece, we are also considering future implementations of WWT in summer research camps for high school students, such as the Summer Science Program.

    Sarrazine, Angela R.; Albin, E.

    2010-01-01

    We report on the International Year of Astronomy (IYA) activities at Fernbank Science Center in Atlanta, GA (USA). The global focus of IYA was to celebrate astronomy and its cultural / scientific contributions, which correlate with the 400th anniversary of Galileo's first look at the heavens with a small telescope. Our planetarium and observatory utilized this opportunity to increase astronomy awareness and education locally. A plethora of special events were organized including two planetarium productions about Galileo and the telescope, special displays in the exhibit hall, two astronaut lectures, a children's workshop with Galileoscopes, and even a Galileo impersonator. Such IYA-related programs increased our overall annual attendance while at the same time served to re-introduce our local audience to astronomy in a creative way.

    "You don't look like a librarian" is a phrase we often hear in the astronomy department or observatory library. Astronomy librarians are a breed apart, and are taking on new and non-traditional roles as information technology evolves. This talk will explore the future of librarians and librarianship through the lens of some of the recent talks given at the sixth "Libraries and Information Services in Astronomy" conference held in Pune, India in February 2010. We will explore the librarian's universe, illustrating how librarians use new technologies to perform such tasks as bibliometrics, how we are re-fashioning our library spaces in an increasingly digital world and how we are confronting the brave new world of Open Access, to name but a few topics.

  1. Visualising Astronomy: "Other Worlds"

    Science.gov (United States)

    Wyatt, R.

    2009-02-01

    The infrastructures that are built and used for astronomical research are financed by - and therefore must be justified to - our society. Astronomy has an innate appeal for people of all ages, partly because it concerns the fascinating, great questions "of life, the Universe and everything" and partly because much of the data obtained with telescopes can be presented as objects of stunning beauty. These are key facts when considering communicating astronomy with the public. This native advantage that astronomy has over many other sciences does not, however, relieve us of the obligation to explain what we are doing to the public at large. There are many reasons for doing this. They range from attracting bright young people into the subject to fuel future research endeavours to convincing decision-takers to allocate large sums of money to finance increasingly expensive and ambitious projects.

    Miller, Scott; Parrish, M.; Gay, P. L.

    2008-05-01

    Learning astronomy can be a life-long process, with the seeds of knowledge planted in K-12 classes blossoming in elective college courses to create adults who actively acquire astronomy content. One of the goals of many astronomy 101 courses is to prepare students to be intelligent consumers of mainstream astronomy content, including magazine articles, popular books, and online news. To meet this goal, astronomy educators need to understand what content is being presented in the media and what level vocabulary is being used. The most simplistic way to address this problem is to examine the topics covered and vocabulary used in mainstream astronomy blogs and news feeds. In this study we looked at a selection of prominent blogs and news feeds and we present a statistical study of the frequency different scientific terms are used and topics are addressed. To make this study possible, software to read in RSS feeds was created. This software had to meet the following design specifications: runs in a reasonable amount of time, removes all XML and HTML code from text, sees words with different capitalizations as the same word, ignores end of sentence or phrase punctuation without ignoring hyphens, and has an editable list of "common English words.” This code will be available after the conference at http://www.starstryder.com. Results of this study find that many of the primary topics of Astronomy 101 classes, such as the HR Diagram, are rarely mentioned in blogs and online news, while often de-emphasized topics, such as extra solar planets, cosmology, and high energy astrophysics, show up regularly.

    Todua, M.

    2016-09-01

    Astronomy in Georgia is generally represented in Abastumani Astrophysical Observatory found in 1932. It is one of the leading scientific institutes in the country. Main fields of research are solar system bodies (including near-Earth asteroids), various aspects of solar physics, stellar astronomy (including binary stars and open clusters), extragalactic objects (AGNs), theoretical astrophysics, cosmology, atmospheric and solar-terrestrial physics. Several telescopes are operational today, as well as the instruments for atmospheric studies. In 2007 the Observatory was integrated with Ilia State University, merging scientific research and education which facilitated the growth of a new generation of researchers. There are groups of astronomers and astrophysicists in other Georgian universities and institutions as well. Georgian scientists collaborate with research centers and universities worldwide. Research groups participate in various international scientific projects. The interest in astronomy in Georgia has been growing, which increases future perspectives of its development in the country.

  5. Improving Science Communication and Engaging the Public in Astronomy and Nature

    2016-01-01

    A partnershipship between Carthage College and the Appalachian Mountain Club has delivered a successful public education and outreach program that merges natural environment topics and astronomy. Over the four years of activity, over 25,000 people have received programming. The effort has trained nature educators, permanent and seasonal AMC staff, and undergraduate physics and astronomy students to integrate diverse topical material and deliver high quality programming to the lay public. Unique to the program is the holistic nature of the material delivered - an 'atypical' astronomy program. Linking observable characteristics of the natural world with astronomical history and phenomena, and emphasizing the unique sequence of events that have led to human life on Earth, the program has changed attitudes and behaviors among the public participants. Successful interventions have included hands-on observing programs (day and night) that link nature content to the observed objects; table-talk presentations on nature/astronomy topics; dark skies preservation workshops; and hands-on activities developed for younger audiences, including schools, camps, and family groups. An extensive evaluation and assessment effort managed by a leading sociologist has demonstrated the effectiveness of the approach, and contributed to continuous improvement in the program content and methods. This work was supported in part by NSF Grant 1432662.

  6. Lessons from Mayan Astronomy

    CERN Document Server

    Loeb, Abraham

    2016-01-01

    The Mayan culture collected exquisite astronomical data for over a millennium. However, it failed to come up with the breakthrough ideas of modern astronomy because the data was analyzed within a mythological culture of astrology that rested upon false but mathematically sophisticated theories about the Universe. Have we learned the necessary lessons to prevent our current scientific culture from resembling Mayan Astronomy? Clearly, data collection by itself is not a guarantee for good science as commonly assumed by funding agencies. A vibrant scientific culture should cultivate multiple approaches to analyzing existing data and to collecting new data.

    The University of Arizona Astronomy Club has been using group research projects to enhance the learning experience of undergraduates in astronomy and related fields. Students work on two projects that employ a peer-mentoring system so they can learn crucial skills and concepts necessary in research environments. Students work on a transiting exoplanet project using the 1.55-meter Kuiper Telescope on Mt. Bigelow in Southern Arizona to collect near-UV and optical wavelength data. The goal of the project is to refine planetary parameters and to attempt to detect exoplanet magnetic fields by searching for near-UV light curve asymmetries. The other project is a survey that utilizes the 12-meter Arizona Radio Observatory on Kitt Peak to search for the spectroscopic signature of infall in nearby starless cores. These are unique projects because students are involved throughout the entire research process, including writing proposals for telescope time, observing at the telescopes, data reduction and analysis, writing papers for publication in journals, and presenting research at scientific conferences. Exoplanet project members are able to receive independent study credit for participating in the research, which helps keep the project on track. Both projects allow students to work on professional research and prepare for several astronomy courses early in their academic career. They also encourage teamwork and mentor-style peer teaching, and can help students identify their own research projects as they expand their knowledge.

    ESA is working on a science-driven discovery portal for all its astronomy missions at ESAC called ESASky. The first public release of this service will be shown, featuring interfaces for sky exploration and for single and multiple targets. It requires no operational knowledge of any of the missions involved. A first public beta release took place in October 2015 and gives users world-wide simplified access to high-level science-ready data products from ESA Astronomy missions plus a number of ESA-produced source catalogues. XMM-Newton data, metadata and products were some of the first to be accessible through ESASky. In the next decade, ESASky aims to include not only ESA missions but also access to data from other space and ground-based astronomy missions and observatories. From a technical point of view, ESASky is a web application that offers all-sky projections of full mission datasets using a new-generation HEALPix projection called HiPS; detailed geometrical footprints to connect all-sky mosaics to individual observations; direct access to the underlying mission-specific science archives and catalogues. The poster will be accompanied by a demo booth at the conference.

    Ruggles, Clive L. N.

    This article describes and defines a number of basic concepts that are commonly used in archaeoastronomy and ethnoastronomy, sometimes in particular ways, and attempts to clarify some of the issues of confusion that frequently arise. It is aimed primarily at archaeologists and ethnographers entering or exploring the field and emphasizes the broad principles that are generally of importance to them, while trying to avoid unnecessary complications as well as technical details. It is not aimed at those studying historical sources from antiquity onward, who need a more sophisticated knowledge of positional astronomy, mathematically formulated. Further detail can be found in a variety of sources, including a number aimed specifically at archaeoastronomers.

  15. Skyscape of an Amazonian Diaspora: Arawak Astronomy in Historical Comparative Perspective

    Science.gov (United States)

    Jara, Fabiola

    The title of this article "Arawak Astronomy" suggests that the research matter concerns the astronomy of an already well-defined ethnographic entity. This however does not do justice to the complexities of Arawak (pre)history. This contribution aims to discuss and connect the available historical and ethnographic data on Arawak astronomies as gathered by the author (Jara 2000), with the most recent research on the archeology and comparative linguistics of the Arawak diaspora. The article argues that Arawak astronomy has to be related to the cultural and sociopolitical continuities and discontinuities of the Arawak diaspora throughout the lowlands of tropical South America. This article recognizes the need to consider Arawak astronomy has an object to be discovered and explained within its local and regional contexts. Notwithstanding these remarks, based on a sustained examination of ethnohistorical and ethnographic sources, this article proposes that Arawak astronomy can be characterized by at least four elements: firstly, a horizon system of observation which combines the observation of the solar solstices and equinoxes with the near heliacal and near cosmic rising or setting of at least seven star groups - the Pleiades, the Hyades, the upper stars of the constellation of Scorpius (including α Sco), Corvus, the Belt of Orion, several stars near Sirius, and the Milky Way. Secondly, the association of the rising and setting of these star groups with the seasonal cycle, mainly with the start and/or of the end of rainy and dry seasons. Thirdly, the widespread association of the stars of the year (most commonly the Pleiades but sometimes Orion or the head of Scorpius) with the beginning of the agricultural cycle and consequently with the end of the heavy rains announcing the time to plant the new fields. The last and fourth commonality are the inscriptions or markings of the origin of the stars in the local landscape, lakes, mountains, and other salient landscape

    2010-01-01

    K-12 educators need effective and relevant astronomy professional development. WISE Telescope (Wide-Field Infrared Survey Explorer) and Spitzer Space Telescope Education programs provided an immersive teacher professional development workshop at Arecibo Observatory in Puerto Rico during the summer of 2009. As many common misconceptions involve scale and distance, teachers worked with Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers built and used basic telescopes, learned about the history of telescopes, explored ground and satellite based telescopes, and explored and worked on models of WISE Telescope. An in-depth explanation of WISE and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. We taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of WISE lenticulars and diagramming of infrared data, listening to light by using speakers hooked up to photoreceptor cells, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars. We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development. Funding was provided by WISE Telescope, Spitzer Space Telescope, Starbucks, Arecibo Observatory, the American Institute of Aeronautics and Astronautics, and the Washington Space Grant Consortium.

  20. Summary: Special Session SpS15: Data Intensive Astronomy

    Science.gov (United States)

    Montmerle, Thierry

    2015-03-01

    A new paradigm in astronomical research has been emerging - ``Data Intensive Astronomy'' that utilizes large amounts of data combined with statistical data analyses. The first research method in astronomy was observations by our eyes. It is well known that the invention of telescope impacted the human view on our Universe (although it was almost limited to the solar system), and lead to Keplerfs law that was later used by Newton to derive his mechanics. Newtonian mechanics then enabled astronomers to provide the theoretical explanation to the motion of the planets. Thus astronomers obtained the second paradigm, theoretical astronomy. Astronomers succeeded to apply various laws of physics to reconcile phenomena in the Universe; e.g., nuclear fusion was found to be the energy source of a star. Theoretical astronomy has been paired with observational astronomy to better understand the background physics in observed phenomena in the Universe. Although theoretical astronomy succeeded to provide good physical explanations qualitatively, it was not easy to have quantitative agreements with observations in the Universe. Since the invention of high-performance computers, however, astronomers succeeded to have the third research method, simulations, to get better agreements with observations. Simulation astronomy developed so rapidly along with the development of computer hardware (CPUs, GPUs, memories, storage systems, networks, and others) and simulation codes.

  2. Introducing astronomy into high school physics curriculum through the use of the University of North Dakota Observatory

    Science.gov (United States)

    Nolby, Caitlin Marie

    Astronomy education is currently lacking in the secondary level classroom. Many programs have been created to remedy this, including research opportunities for students and training workshops for educators. These reach only a small fraction of the population however, while remaining students still lack the opportunity to learn astronomy at the secondary level. This research addresses the creation of a program that will make astronomy education a recurring option for students across North Dakota through implementation of a two-week astronomy course at Grand Forks Central High School (GFCHS) in a class of 19 physics students. During ten class periods from April 16, 2012 through April 27, 2012, instruction included presentation of basic astronomy concepts and observational techniques as well as student participation in demonstrations and in-class activities. Original lesson plans also included a group research project on the astrometry of an asteroid. Students were given the option to visit the University of North Dakota (UND) Observatory the evening of April 20, 2012 for a public "star party" where they received a tour of the university's telescopes and research equipment. Students also took a field trip to the John D. Odegard School of Aerospace Sciences to tour Aviation and Space Studies facilities at UND on April 25, 2012. Students were given a pre-test at the start of the course, daily exit surveys at the end of each class period, and a post-test at the end of the two weeks. These assessments were used to evaluate student enjoyment, progress, and overall perception of the course. The research also identified common misconceptions in astronomy held by the learners and the most effective teaching methods. It was found that this course was overall successful in promoting the students' learning of astronomy. This analysis has been used to make improvements in future installments of the course and it is now available online to educators for use in the classroom.

  3. Modelled hydraulic redistribution by sunflower (Helianthus annuus L.) matches observed data only after including night-time transpiration.

    The movement of water from moist to dry soil layers through the root systems of plants, referred to as hydraulic redistribution (HR), occurs throughout the world and is thought to influence carbon and water budgets and ecosystem functioning. The realized hydrologic, biogeochemical and ecological consequences of HR depend on the amount of redistributed water, whereas the ability to assess these impacts requires models that correctly capture HR magnitude and timing. Using several soil types and two ecotypes of sunflower (Helianthus annuus L.) in split-pot experiments, we examined how well the widely used HR modelling formulation developed by Ryel et al. matched experimental determination of HR across a range of water potential driving gradients. H. annuus carries out extensive night-time transpiration, and although over the last decade it has become more widely recognized that night-time transpiration occurs in multiple species and many ecosystems, the original Ryel et al. formulation does not include the effect of night-time transpiration on HR. We developed and added a representation of night-time transpiration into the formulation, and only then was the model able to capture the dynamics and magnitude of HR we observed as soils dried and night-time stomatal behaviour changed, both influencing HR.

  5. Strategies for Teaching Astronomy

    Science.gov (United States)

    Bennett, J.

    2000-12-01

    No matter whether you are teaching school children, undergraduates, or colleagues, a few key strategies are always useful. I will present and give examples for the following five key strategies for teaching astronomy. 1. Provide a Contextual Framework: It is much easier to learn new facts or concepts if they can be ``binned" into some kind of pre-existing mental framework. Unless your listeners are already familiar with the basic ideas of modern astronomy (such as the hierarchy of structure in the universe, the scale of the universe, and the origin of the universe), you must provide this before going into the details of how we've developed this modern picture through history. 2. Create Conditions for Conceptual Change: Many people hold misconceptions about astronomical ideas. Therefore we cannot teach them the correct ideas unless we first help them unlearn their prior misconceptions. 3. Make the Material Relevant: It's human nature to be more interested in subjects that seem relevant to our lives. Therefore we must always show students the many connections between astronomy and their personal concerns, such as emphasizing how we are ``star stuff" (in the words of Carl Sagan), how studying other planets helps us understand our own, and so on. 4. Limit Use of Jargon: The number of new terms in many introductory astronomy books is larger than the number of words taught in many first courses in foreign language. This means the books are essentially teaching astronomy in a foreign language, which is a clear recipe for failure. We must find ways to replace jargon with plain language. 5. Challenge Your Students: Don't dumb your teaching down; by and large, students will rise to meet your expectations, as long as you follow the other strategies and practice good teaching.

    "The British National Space Centre partnership has recognised for some time that Space and Astronomy are particularly attractive subjects for school students and that including these in the science curriculum can have a positive effect on student interest in science. Drivers are that the number of young people studying science and engineering subjects at A-level and beyond is declining; young people should have an understanding of the importance of science and technology to the world around them; and that UK space industry (including technology, engineering, space science, Earth observation science) must renew itself." BRINGING SPACE INTO SCHOOL Professor Martin Barstow, University of Leicester Published by PPARC on behalf of the British National Space Centre Partnership October 2005 "It has become more and more difficult to persuade young people to follow a career in STEM (Science, Technology, Engineering & Mathematics) subjects. Across the EU, the number of graduates in STEM subjects has dropped from 24.3% in 2002 to 22.6% in 2011" (Source EUSTAT) It was Martin Barstow's report in 2005 that started my attempt to interest people in Science and Technology, At Ormiston Victory Academy (OVA) for the past two years, we have embarked on a program to enthuse pupils to study science related subject through the medium of Astronomy. We teach Edexcel GCSE Astronomy to a joint parent and pupil group. They study together and at the end of the course, both take the GCSE examination. The idea is that the pupils see that science is important to their parents and that a very practical facet of science is also fun. Astronomy is a multidisciplinary course bringing together elements of Science, Maths, Technology, Geography and History. It is hoped that the enthusiasm shown by the pupils will spill over into the mainstream subjects including maths. The parents get an idea of the work and level of knowledge required by their children to complete a GCSE level subject. They also report

On these and the three following days ( Phase 3 : November 20--22), the `active period' will be in the six-hour interval from 15h to 21h UT [2]. Various events are planned to happen at certain times and in certain places on the WWW, keeping the programme lively and enhancing the interaction by ensuring continued attention and expectation by the participants. During Phases 2 and 3, nine or more `shops' will be available in the Astronomy On-Line WWW `marketplaces' for consultation by the participants. They will display a variety of `goods' (activities) at different levels of complexity in order to attract participants of different age groups, among others: General information; Collaborative projects which require observations by many groups all over the continent; Real astronomical observations to be submitted and executed with telescopes at participating, professional observatories; Prepared exercises which may include guided searches on the WWW; Opportunities to talk to professional astronomers, etc. More details are available at the above mentioned WWW sites. Ideas for further activities are now being actively solicited by the Steering Committees. At the end, the various results will be presented on the WWW in the form of short reports which may be commented upon, as far as possible in real time. A `final event' which will `unite' participants from all over Europe will be planned on the last day. Notes: [1] The EAAE was founded in November 1994 (cf. ESO Press Release 17/94 of 2 December 1994) and now has several hundred members located in virtually all European countries; most are secondary school physics teachers with a particular interest in astronomy.

  11. Berkeley's Advanced Labs for Undergraduate Astronomy Majors

    Science.gov (United States)

    Heiles, C.

    1998-12-01

    We currently offer three advanced laboratory courses for undergraduate majors: optical, IR, and radio. These courses contain both intellectual and practical content; in this talk we focus on the radio lab as a representative example. The first half of the semester concentrates on fundamentals of microwave electronics and radio astronomy techniques in four formal laboratory exercises which emphasize hands-on use of microwave devices, laboratory instruments, and computer-controlled data taking. The second half of the course emphasizes astronomy, using a horn with ~ 1 m(2) aperture to map the HI in the Galaxy and a two-element interferometer composed of ~ 1 m diameter dishes on a ~ 10 m baseline to measure accurate positions of radio sources and accurate diameters for the Sun and Moon. These experiments and observations offer ideal opportunities for teaching coordinates, time, rotation matrices, data reduction techniques, least squares, signal processing, image processing, Fourier transforms, and laboratory and astronomical instrumentation. The students can't get along without using computers as actually used by astronomers. We stay away from packaged software such as IRAF, which are ``black boxes''; rather, students learn far more by writing their own software, usually for the first time. They use the IDL language to take and reduce data and prepare them for the lab reports. We insist on quality reports---including tables, postscript graphs and images, correct grammar, spelling, and all the rest---and we strongly urge (successfully!) the students to use LATEX. The other two lab courses have the same emphasis: the guiding spirit is to place the students in a real-life research-like situation. There is too much to do, so students perform the work in small groups of 3 or 4 and groups are encouraged to share their knowledge. Lab reports are written individually. These courses are very demanding, requiring an average of 20 hours per week from the students (and probably

  13. Astronomy and Shakespeare's Hamlet.

    Science.gov (United States)

    Usher, P. D.

    1996-05-01

    Payne-Gaposchkin and others have suggested that Hamlet shows evidence of the Bard's awareness of the astronomical revolutions of the sixteenth century. I summarize major arguments and note that the play's themes recur in modern astronomy teaching and research: (1) The play amounts to a redefinition of universal order and humankind's position in it. (2) There is interplay between appearance and reality. Such a contrast is commonplace wherever superficial celestial appearances obscure underlying physical realities, the nature of which emerge as the tale unfolds. (3) The outermost sphere of the Ptolemaic and Copernican models seems to encase humanity, who are liberated by the reality of Digges' model and the implications advanced by Bruno. Similarly the oppressiveness of the castle interior is relieved by the observing platform which enables the heavens to be viewed in their true light. (4) Hamlet could be bounded in a nut-shell and count himself a king of infinite space, were it not that he has bad dreams. These concern the subversiveness of the new doctrine, for Hamlet refers to the infinite universe only hypothetically and in the presence of Rosencrantz and Guildenstern, who are named for relatives of the Danish astronomer Brahe. (5) Hamlet, and Brahe and Bruno, have connections to the university at Wittenberg, as does the Copernican champion Rheticus. (6) Ways are needed to reveal both the truths of nature, and the true nature of Danish royalty. Those unaccustomed to science think that there is madness in Hamlet's method. In particular, `doubt' is advanced as a methodological principle of inquiry. (7) The impression of normalcy and propriety in the upper reaches of society is like the false impression of an encapsulating universe. In Hamlet this duality is dramatized tragically, whereas in King John (cf. BAAS 27, 1325, 1995) it is not; for by 1601 when the writing of Hamlet was probably completed, Shakespeare would have known of the martyrdom of Bruno the previous

We analyse here the relations between astrology and astronomy, as well as the criticisms opposed by the latter to the former. We show that most of these criticisms are weak. Much stronger ones emerge from the analysis of the astrological practice compared to the scientific method, leading us to conclude to the non-scientificity of astrology. Then we return to the success of astrology, and from its analysis we propose a renewed (and prophylactic) rôle for astronomy in society.

    The use of space techniques continues to play a key role in the advance of astrophysics by providing access to the entire electromagnetic spectrum from the radio observations to the high energy gamma rays. The increasing size, complexity and cost of large space observatories places a growing emphasis on international collaboration. Furthermore, combining existing and future datasets from space and ground based observatories is an emerging mode of powerful and relatively inexpensive research to address problems that can only be tackled by the application of large multi-wavelength observations. If the present set of space and ground-based astronomy facilities today is impressive and complete, with space and ground based astronomy telescopes nicely complementing each other, the situation becomes concerning and critical in the next 10-20 years. In fact, only a few main space missions are planned, possibly restricted to JWST and, perhaps, WFIRST and SPICA, since no other main facilities are already recommended. A "Working Group on the Future of Space Astronomy" was established at the 38th COSPAR Assembly held in Bremen, Germany in July 2010. The purpose of this Working Group was to establish a roadmap for future major space missions to complement future large ground-based telescopes. This paper presents the results of this study including a number of recommendations and a road map for the next decades of Space Astronomy research.

    The use of infrared spectroscopy in astronomy has increased dramatically in the past ten years. The broad design considerations are discussed in terms of wavelength coverage and resolution. Three rough resolution ranges, lambda/Delta lambda of approximately 100, 1000 and 10,000, are identified in which various types of astronomical problems can be studied. Numerous existing systems are briefly discussed and references are given to more complete descriptions.

    The purpose of the project was to increase minority interest and appreciation of science using astronomy as a tool. This goal was achieved by inviting high school minority students and their teachers to the campus of Western Kentucky University to participate along with minority role models in team based learning experiences. All participants worked together in many hands-on activities and events centered around the exploration of space.

  18. Radio astronomy from space

    Woan, G.

    2011-04-01

    At frequencies below about 30 MHz, radio astronomy becomes increasingly difficult from the Earth's surface, mainly due to a combination of poor ionospheric seeing and strong terrestrial interference. The obvious move is to space, either as free-flying spacecraft or with a telescope located somewhere on the Moon. All the major space agencies have a renewed interest in the Moon as a site for exploration and science, and low-frequency radio astronomy is probably the strongest of the astronomical objectives put forward in these programmes. Although the Sun is a strong source of interference in extra-solar system work, it is also a prime target for study in itself. A constellation of satellites (as proposed for the SIRA mission) would be able to image both the Sun and the inner heliosphere over the entire low-frequency band. Here we investigate some of the advantages and limitations of astronomy at these very low frequencies, using space- and lunar-based antennas.

  19. Invited review article: IceCube: an instrument for neutrino astronomy.

    2010-08-01

    Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer-scale neutrino detectors were required. The first such instrument, IceCube, is near completion and taking data. The IceCube project transforms 1 km(3) of deep and ultratransparent Antarctic ice into a particle detector. A total of 5160 optical sensors is embedded into a gigaton of Antarctic ice to detect the Cherenkov light emitted by secondary particles produced when neutrinos interact with nuclei in the ice. Each optical sensor is a complete data acquisition system including a phototube, digitization electronics, control and trigger systems, and light-emitting diodes for calibration. The light patterns reveal the type (flavor) of neutrino interaction and the energy and direction of the neutrino, making neutrino astronomy possible. The scientific missions of IceCube include such varied tasks as the search for sources of cosmic rays, the observation of galactic supernova explosions, the search for dark matter, and the study of the neutrinos themselves. These reach energies well beyond those produced with accelerator beams. The outline of this review is as follows: neutrino astronomy and kilometer-scale detectors, high-energy neutrino telescopes: methodologies of neutrino detection, IceCube hardware, high-energy neutrino telescopes: beyond astronomy, and future projects.

  20. Observing nebulae

    CERN Document Server

    Griffiths, Martin

    2016-01-01

    This book enables anyone with suitable instruments to undertake an examination of nebulae and see or photograph them in detail. Nebulae, ethereal clouds of gas and dust, are among the most beautiful objects to view in the night sky. These star-forming regions are a common target for observers and photographers. Griffiths describes many of the brightest and best nebulae and includes some challenges for the more experienced observer. Readers learn the many interesting astrophysical properties of these clouds, which are an important subject of study in astronomy and astrobiology. Non-mathematical in approach, the text is easily accessible to anyone with an interest in the subject. A special feature is the inclusion of an observational guide to 70 objects personally observed or imaged by the author. The guide also includes photographs of each object for ease of identification along with their celestial coordinates, magnitudes and other pertinent information. Observing Nebulae provides a ready resource to allow an...

It is gratifying to note that several students, after going through one or more of these courses, have indeed made commitments to pursue Astronomy as their career, some of them even obtaining admissions in to the institutes and universities in India and abroad for further studies in this field.

  2. Exploring Metacogntive Visual Literacy Tasks for Teaching Astronomy

    Science.gov (United States)

    Slater, Timothy F.; Slater, S.; Dwyer, W.

    2010-01-01

    Undoubtedly, astronomy is a scientific enterprise which often results in colorful and inspirational images of the cosmos that naturally capture our attention. Students encountering astronomy in the college classroom are often bombarded with images, movies, simulations, conceptual cartoons, graphs, and charts intended to convey the substance and technological advancement inherent in astronomy. For students who self-identify themselves as visual learners, this aspect can make the science of astronomy come alive. For students who naturally attend to visual aesthetics, this aspect can make astronomy seem relevant. In other words, the visual nature that accompanies much of the scientific realm of astronomy has the ability to connect a wide range of students to science, not just those few who have great abilities and inclinations toward the mathematical analysis world. Indeed, this is fortunate for teachers of astronomy, who actively try to find ways to connect and build astronomical understanding with a broad range of student interests, motivations, and abilities. In the context of learning science, metacognition describes students’ self-monitoring, -regulation, and -awareness when thinking about learning. As such, metacognition is one of the foundational pillars supporting what we know about how people learn. Yet, the astronomy teaching and learning community knows very little about how to operationalize and support students’ metacognition in the classroom. In response, the Conceptual Astronomy, Physics and Earth sciences Research (CAPER) Team is developing and pilot-testing metacogntive tasks in the context of astronomy that focus on visual literacy of astronomical phenomena. In the initial versions, students are presented with a scientifically inaccurate narrative supposedly describing visual information, including images and graphical information, and asked to assess and correct the narrative, in the form of peer evaluation. To guide student thinking, students

    2013-01-01

    My successful programs have included telescope observations, hands-on activities, and edible astronomy demonstrations for: outdoor concerts or music festivals; the National Mall; churches, synagogues, seminaries, or clergy conferences; the Ronald McDonald House of Long Island (New Hyde Park, NY), the Winthrop University Hospital Children’s Medical Center (Mineola, NY); the Fresh Air Fund summer camps; a Halloween star party with costumed kids looking through telescopes; a Super Bowl Star Party; the World Science Festival (NYC); the Princeton University Science and Engineering Expo; the USA Science and Engineering Festival; and the NYC Columbus Day Parade. These outreach activities have reached thousands of people including many young girls. Information was also provided about local science museums, citizen science projects, astronomy educational sites, and astronomy clubs to encourage learning after these events. In 2010 I created Astronomy Night on the National Mall (co-sponsored the White House Office of Science and Technology Policy) with the participation of astronomy clubs, Chandra X-Ray Center, STScI, NASA, NOAO, NSF and the National Air and Space Museum. Since 2009 my NASA-funded Music and Astronomy Under the Stars (MAUS) program has brought astronomy to 50,000 music lovers who attended the Central Park Jazz, Newport Folk, Tanglewood, or Ravinia music festivals or classical, folk, rock, pop, opera, or county-western concerts in local parks assisted by astronomy clubs. MAUS is an evening, nighttime, and cloudy weather traveling astronomy program combining solar, optical, and radio telescope observations; a live image projection system; large outdoor posters and banners; videos; and hands-on activities before and after the concerts or at intermission.

    Glaser, Scott T.; Strovers, Brian K.

    2011-01-01

    Airborne infrared astronomy has a long successful history, albeit relatively unknown outside of the astronomy community. A major problem with ground based infrared astronomy is the absorption and scatter of infrared energy by water in the atmosphere. Observing the universe from above 40,000 ft puts the observation platform above 99% of the water vapor in the atmosphere, thereby addressing this problem at a fraction of the cost of space based systems. The Stratospheric Observatory For Infrared Astronomy (SOFIA) aircraft is the most ambitious foray into the field of airborne infrared astronomy in history. Using a 747SP (The Boeing Company, Chicago, Illinois) aircraft modified with a 2.5m telescope located in the aft section of the fuselage, the SOFIA endeavors to provide views of the universe never before possible and at a fraction of the cost of space based systems. The modification to the airplane includes moveable doors and aperture that expose the telescope assembly. The telescope assembly is aimed and stabilized using a multitude of on board systems. This modification has the potential to cause aerodynamic anomalies that could induce undesired forces either at the cavity itself or indirectly due to interference with the empennage, both of which could cause handling qualities issues. As a result, an extensive analysis and flight test program was conducted from December 2009 through March 2011. Several methods, including a Lower Order Equivalent Systems analysis and pilot assessment, were used to ascertain the effects of the modification. The SOFIA modification was found to cause no adverse handling qualities effects and the aircraft was cleared for operational use. This paper discusses the history and modification to the aircraft, development of test procedures and analysis, results of testing and analysis, lessons learned for future projects and justification for operational certification.

    Stoeva, Penka; Stoev, Alexey

    In recent years, more and more attention is paid to educational programmes, which are closely connected with the process of scientific research. Such programmes are developed in collab-oration and included in the schools, universities and scientific institutes in Bulgaria. They are also used in the organization of public events aimed to demonstrate beauty, relevance and significance of Space and Earth science to the whole world. During the last four years, So-lar-Terrestrial Influences Institute of the Bulgarian Academy of Sciences, and the Yuri Gagarin Public Astronomical Observatory and Planetarium, Stara Zagora succeeded to build an ex-cellent partnership, working on the International Heliophysical year and International Year of Astronomy -global efforts initiated by the UNESCO and the International Astronomical Union (IAU) to help the citizens of the world rediscover their place in the Universe. They organized and tutored all the Astronomical Observatories and Planetaria, and teachers from all around Bulgaria to participate in the world initiatives Solar Week, Sun-Earth Day,Yuri's Night, World Astronomy day and World Space week, and use them in the process of education and public outreach. After the official closing of the International Heliophysical year, the IHY follow-on activities in Bulgaria continued and were devoted to the International Year of Astronomy 2009. A lot of lectures, public talks and exhibitions have been organized. Stara Zagora became a host of IHY Space Weather Monitor -SID (Sudden Ionospheric Disturbances), numerous of educational materials have been adapted and translated in Bulgarian. Cycle of lectures "Epock of Great astronomical discoveries", devoted to the International Year of Astronomy was given in April 2009 in the Stara Zagora Art Gallery. Participation in the cornerstone projects of the International Year of Astronomy 2009 was organized: "100 hours of Astronomy" -ob-servations with small telescopes in the period of 5 -9 April

    Although it is not yet visible, much progress has been made on the Astronomy Genealogy Project (AstroGen) since it was accepted as a project of the Historical Astronomy Division (HAD) three years ago. AstroGen will list the world's astronomers with information about their highest degrees and advisors. (In academic genealogy, your thesis advisor is your parent.) A small group (the AstroGen Team) has compiled a database of approximately 12,000 individuals who have earned doctorates with theses (dissertations) on topics in astronomy, astrophysics, cosmology, or planetary science. These include nearly all those submitted in Australia, Canada, the Netherlands, and New Zealand, and most of those in the United States (all through 2014 for most universities and all through 1990 for all). We are compiling more information than is maintained by the Mathematics Genealogy Project (MGP). In addition to name, degree, university, year of degree, and thesis advisor(s), all provided by MGP as well, we are including years of birth and death when available, mentors in addition to advisors, and links to the thesis when it is online and to the person's web page or obituary, when we can find it. We are still struggling with some questions, such as the boundaries of inclusion and whether or not to include subfields of astronomy. We believe that AstroGen will be a valuable resource for historians of science as well as a source of entertainment for those who like to look up their academic family trees. A dedicated researcher following links from AstroGen will be able to learn quite a lot about the careers of astronomy graduates of a particular university, country, or era. We are still seeking volunteers to enter the graduates of one or more universities.

Now, astrophysics has become a key subject in Guangdong Province, and the Astronomy Science and Technology Research Laboratory one of the key laboratories of the Department of Education of the Guangdong Province. Many undergraduate students, working under the tutorship of faculty members completed their thesis at the Center for Astrophysics in Guangzhou.

  9. Photonic Astronomy and Quantum Optics

    CERN Document Server

    Dravins, Dainis

    Quantum optics potentially offers an information channel from the Universe beyond the established ones of imaging and spectroscopy. All existing cameras and all spectrometers measure aspects of the first-order spatial and/or temporal coherence of light. However, light has additional degrees of freedom, manifest in the statistics of photon arrival times, or in the amount of photon orbital angular momentum. Such quantum-optical measures may carry information on how the light was created at the source, and whether it reached the observer directly or via some intermediate process. Astronomical quantum optics may help to clarify emission processes in natural laser sources and in the environments of compact objects, while high-speed photon-counting with digital signal handling enables multi-element and long-baseline versions of the intensity interferometer. Time resolutions of nanoseconds are required, as are large photon fluxes, making photonic astronomy very timely in an era of large telescopes.

  10. Linear regression in astronomy. II

    Science.gov (United States)

    Feigelson, Eric D.; Babu, Gutti J.

    1992-01-01

    A wide variety of least-squares linear regression procedures used in observational astronomy, particularly investigations of the cosmic distance scale, are presented and discussed. The classes of linear models considered are (1) unweighted regression lines, with bootstrap and jackknife resampling; (2) regression solutions when measurement error, in one or both variables, dominates the scatter; (3) methods to apply a calibration line to new data; (4) truncated regression models, which apply to flux-limited data sets; and (5) censored regression models, which apply when nondetections are present. For the calibration problem we develop two new procedures: a formula for the intercept offset between two parallel data sets, which propagates slope errors from one regression to the other; and a generalization of the Working-Hotelling confidence bands to nonstandard least-squares lines. They can provide improved error analysis for Faber-Jackson, Tully-Fisher, and similar cosmic distance scale relations.

    This book brings together the lectures given at the Les Houches summer school "Infrared space astronomy, today and tomorrow". It gives a wide overview of infrared astronomy, a wavelength domain crucial for studies of the solar system, stars at the beginning and end of their lives, interstellar matter and galaxies at all distances. Recent developments in observational techniques have been tremendous. The first contributions give an introduction to the basic physical processes and methods of detection and data processing. They are followed by a series of lectures dealing with the wide variety of astronomical objects that can be seen in the infrared.

  12. A superconducting tunnel junction receiver for submillimeter astronomy, and analysis of observations of post-AGB star molecular envelopes. [AGB (asymptotic giant branch)

    Energy Technology Data Exchange (ETDEWEB)

    Jaminet, P.A.

    1992-01-01

    A heterodyne receiver designed for astronomical use between 450 and 520 GHz has been constructed. Very low capacitance (C [approximately] 5-10 fF) Superconductor-Insulator-Superconductor (SIS) junctions have been fabricated as the detectors; these junctions lie on the edges of niobium thin films and form Nb-Al-Al[sub 2]O[sub 3]-Al-Nb sandwiches. The double sideband (DSB) receiver noise temperature is between 400 K and 800 K throughout the 70 GHz band. In addition, detailed modelling and analysis of astronomical observations of two post-AGB (Asymptotic Giant Branch) stars was performed. The observations were made with an SIS receiver designed for 345 GHz. CO observations and modelling of the young planetary nebula NGC 7027 provided the best determination yet of its AGB mass loss rate, the first direct evidence for bipolarity in its AGB mass loss, evidence for close hydrodynamic coupling between the planetary nebula and the relic AGB wind, and evidence for evolution in the metallicity of the stellar wind. Observations of the proto-planetary nebula CRL 2688 found evidence for spatially extended fast wind emission with a non-bipolar morphology, and evidence for evolution is elemental abundances in the stellar wind.

    2014-01-01

    The University of Chicago Multiwavelength Astronomy modules are web-based lessons covering the history, science, tools, and impact of astronomy across the wavebands, from gamma ray to infrared. Each waveband includes four lessons addressing one aspect of its development. The lessons are narrated by a historical docent or practicing scientist who contributed to a scientific discovery or instrument design significant to astronomical progress. The process of building each lesson began with an interview conducted with the scientist, or the consultation of a memoir or oral history transcript for historical docents. The source was then excerpted to develop a lesson and supplemented by archival material from the University of Chicago Library and other archives; NASA media; and participant contributed photographs, light curves, and spectra. Practicing educators also participated in the lesson development and evaluation. In July 2013, the University of Chicago sponsored 9 teachers and 15 students to participate in a STEM education program designed to engage participants as co-learners as they used the Multiwavelength Astronomy lessons in conjunction with talks given by the participating scientists. Teachers also practiced implementation of the resources with students and designed authentic research activities that make use of NASA mission data, which were undertaken as mini-research projects by student teams during the course of the program. This poster will introduce the Multiwavelength Astronomy web modules; highlight educator experiences in their use with high school audiences; and analyze the module development process, framing the benefits to and contributions of each of the stakeholders including practicing astronomers in research and space centers, high school science educators, high school students, University libraries and archives, and the NASA Science Mission Directorate. The development of these resources, and the summer professional development workshops were

    In light of the recent IceCube evidence for a flux of extraterrestrial neutrinos, we revisit the prospect of observing the sources of the Galactic cosmic rays. In particular, we update the predictions for the neutrino flux expected from sources in the nearby star-forming region in Cygnus taking into account recent TeV gamma ray measurements of their spectra. We consider the three Milagro sources: MGRO J2019+37, MGRO J1908+06 and MGRO J2031+41 and calculate the attainable confidence level limits and statistical significance as a function of the exposure time. We also evaluate the prospects for a kilometer-scale detector in the Mediterranean to observe and elucidate the origin of the cosmic neutrino flux measured by IceCube.

  17. Astrophysical Model Selection in Gravitational Wave Astronomy

    Science.gov (United States)

    Adams, Matthew R.; Cornish, Neil J.; Littenberg, Tyson B.

    2012-01-01

    Theoretical studies in gravitational wave astronomy have mostly focused on the information that can be extracted from individual detections, such as the mass of a binary system and its location in space. Here we consider how the information from multiple detections can be used to constrain astrophysical population models. This seemingly simple problem is made challenging by the high dimensionality and high degree of correlation in the parameter spaces that describe the signals, and by the complexity of the astrophysical models, which can also depend on a large number of parameters, some of which might not be directly constrained by the observations. We present a method for constraining population models using a hierarchical Bayesian modeling approach which simultaneously infers the source parameters and population model and provides the joint probability distributions for both. We illustrate this approach by considering the constraints that can be placed on population models for galactic white dwarf binaries using a future space-based gravitational wave detector. We find that a mission that is able to resolve approximately 5000 of the shortest period binaries will be able to constrain the population model parameters, including the chirp mass distribution and a characteristic galaxy disk radius to within a few percent. This compares favorably to existing bounds, where electromagnetic observations of stars in the galaxy constrain disk radii to within 20%.

  18. Dyslexia and Astronomy

    Science.gov (United States)

    Schneps, Matthew H.; Greenhill, L. J.; Rose, L. T.

    2007-12-01

    Dyslexia is a hereditary neurological disability that impairs reading. It is believed that anywhere from 5% to 20% of all people in the US may have dyslexia to a greater or lesser degree. Though dyslexia is common, it is a "silent disability" in the sense that it is not easy to tell which individuals suffer from dyslexia and which do not. There is a substantial body of evidence to suggest that people with dyslexia tend to do well in science. For example, Baruj Benacerraf, a Nobel laureate in medicine, is among those whose impairments have been documented and studied. Given that dyslexia was not diagnosed in schools prior to the late 1970's, many established science researchers may have dyslexia and be unaware of their impairment. Therefore, it would not be surprising to find that substantial numbers of scientists working in the fields of astronomy and astrophysics have dyslexia, and yet be unaware of the effects this disability has had on their research. A recently proposed theory by the authors suggests that there may be specific neurological reasons why those with dyslexia may be predisposed to science, and predicts that dyslexia may be associated with enhanced abilities for certain types of visual processing, with special implications for image processing. Our study, funded by the NSF, investigates this hypothesis in the context of astronomy and astrophysics. We expect this work will uncover and document challenges faced by scientists with dyslexia, but perhaps more importantly, lead to an understanding of the strengths these scientists bring to research. The program will serve as a clearing-house of information for scientists and students with dyslexia, and begin to provide mentoring for young people with dyslexia interested in astronomy. Scientists who have reason to believe they may have dyslexia are encouraged to contact the authors.

    The practice of astrology can be traced in most if not all human societies, in most time periods. Astrology has prehistoric origins and flourishes in the modern world, where it may be understood as a form of ethnoastronomy - astronomy practiced by the people. The Western tradition, which originated in Mesopotamia and was developed in the Greek world, has been most studied by academics. However, India is also home to a tradition which has survived in a continuous lineage for 2,000 years. Complex systems of astrology also developed in China and Mesoamerica, while all other human societies appear to seek social and religious meaning in the stars.

    In the age of asteroid mining the ability to find promising ore-bearing bodies will be valuable. This will give rise to a new discipline- "Applied Astronomy". Just as most geologists work in industry, not in academia, the same will be true of astronomers. Just how rare or common ore-rich asteroids are likely to be, and the skills needed to assay their value, are discussed here, with an emphasis on remote - telescopic - methods. Also considered are the resources needed to conduct extensive surveys of asteroids for prospecting purposes, and the cost and timescale involved. The longer-term need for applied astronomers is also covered.

    Under Connecticut Skies examines the history of astronomy at Van Vleck Observatory, located on the campus of Wesleyan University in Middletown, Connecticut. Since its dedication in June of 1916, Van Vleck has been an important site of astronomical research, teaching, and public outreach. Over a thousand visitors pass through the observatory each year, and regular public observing nights happen year-round in cooperation with the Astronomical Society of Greater Hartford. Our project explores the place-based nature of astronomical research, the scientific instruments, labor, and individuals that have connected places around the world in networks of observation, and the broader history of how observational astronomy has linked local people, amateur observers, professional astronomers, and the tools and objects that have facilitated their work under Connecticut’s skies over the past 100 years. Our research team has produced a historical exhibition to help commemorate the observatory’s centennial that opened to the public in May of 2016. Our work included collecting, documenting, and interpretting this history through objects, archival documents, oral histories, photographs, and more. The result is both a museum and a working history "laboratory" for use by student and professional researchers. In addition to the exhibit itself, we have engaged in new interpretive programs to help bring the history of astronomy to life. Future work will include digitization of documents and teaching slides, further collection of oral histories, and expanding the collection to the web for use by off-site researches.

    Stars in final phases of evolution are sites of highest energetic phenomena of the Universe. The understanding of their mechanisms is based on the observation of the X and gamma rays from the sources. The Simbol-X French-Italian project is a novel concept of telescope with two satellites flying in formation. This space mission combines upgraded optics from X-ray telescopes with detection Systems from gamma-ray telescopes. CEA Saclay involved in major space missions for gamma astronomy is in charge of the definition and the design of the High Energy Detector (HED) of Simbol-X to cover the spectral range from 8 to 80 keV. Two generations of micro-cameras called Caliste have been designed, fabricated and tested. They integrate cadmium telluride (CdTe) crystals and optimised front-end electronics named Idef-X. The hybridization technique enables to put them side by side as a mosaic to achieve for the first time a CdTe detection plane with fine spatial resolution (600 {mu}m) and arbitrarily large surface. By setting up test benches and leading test campaigns, I was involved in the fabrication of Caliste prototypes and I assessed temporal, spatial and spectral resolutions. At the conclusion of experiments and simulations, I propose a detector type, operating conditions and digital processing on board the spacecraft to optimise HED performance. The best detector candidate is CdTe Schottky, well suited to high resolution spectroscopy; however, it suffers from lost in stability during biasing. Beyond Simbol-X mission, I studied theoretically and experimentally this kind of detector to build an updated model that can apply to other projects of gamma spectroscopy and imaging. (author)

  4. Women's and men's career choices in astronomy and astrophysics

    In order to understand gender differences in persistence and attrition from astronomy and physics, the Longitudinal Study of Astronomy Graduate Students follows a cohort of people who were graduate students in astronomy or astrophysics during 2006-07. The first survey was conducted during 2007-08 and the second during 2012-13, when many of the respondents had left graduate school and were working. For respondents who had completed PhDs and were not postdocs, we tested the effects of four major concepts on attrition from physics and astronomy. These concepts included: the imposter syndrome, mentoring and advising during graduate school, work-family balance, and being female. We hypothesized that women would be more likely than men to work outside of astronomy and physics. However, results from the study show that there is no direct independent effect of being female on attrition. Rather, women are more likely to leave astronomy because they are more likely than men to (1) experience difficulties related to the need to find a job for a spouse or partner in the same geographical area, and (2) report less than satisfactory advising during graduate school. This research identifies specific areas of concern that can be addressed by the scientific community to increase the retention of all people, but especially women, in astronomy, physics, and related fields.

    2016-01-01

    A review of modernization and growth of ground based optical and near-infrared astrophysical observational facilities in the globe attributed to the recent technological developments in optomechanical, electronics and computer science areas is presented. Hubble Space Telescope (HST) and speckle and adaptive ground based imaging have obtained images better than 0.1 arc sec angular resolution bringing the celestial objects closer to us at least by a factor of 10 during the last two decades. From the light gathering point of view, building of large size (more than 5 meter aperture) ground based optical and nearinfrared telescopes based on latest technology have become economical in recent years. Consequently, in the world, a few 8-10 meter size ground-based optical and near-infrared telescopes are being used for observations of the celestial objects, three 25-40 meter size are under design stage and making of a ~ 100 meter size telescope is under planning stage. In India, the largest sized optical and near-infra...

    Full Text Available A powerful characterization technique, pulse capacitance-voltage (CV technique, was used to investigate oxide traps before and after annealing for lanthanide zirconium oxide thin films deposited on n-type Si (111 substrates at 300 °C by liquid injection Atomic Layer Deposition (ALD. The results indicated that: (1 more traps were observed compared to the conventional capacitance-voltage characterization method in LaZrOx; (2 the time-dependent trapping/de-trapping was influenced by the edge time, width and peak-to-peak voltage of a gate voltage pulse. Post deposition annealing was performed at 700 °C, 800 °C and 900 °C in N2 ambient for 15 s to the samples with 200 ALD cycles. The effect of the high temperature annealing on oxide traps and leakage current were subsequently explored. It showed that more traps were generated after annealing with the trap density increasing from 1.41 × 1012 cm−2 for as-deposited sample to 4.55 × 1012 cm−2 for the 800 °C annealed one. In addition, the leakage current density increase from about 10−6 A/cm2 at Vg = +0.5 V for the as-deposited sample to 10−3 A/cm2 at Vg = +0.5 V for the 900 °C annealed one.

    The nascent field of gravitational wave astronomy offers many opportunities for effective and inspirational astronomy outreach. Gravitational waves, the `ripples in spacetime' predicted by Einstein's general theory of relativity, are produced by some of the most energetic and dramatic phenomena in the cosmos, including black holes, neutron stars and supernovae - and their discovery should help to address a number of fundamental questions in physics, from the evolution of stars and galaxies to the origin of dark energy and the nature of spacetime itself. Moreover, the cutting-edge technology developed to search for gravitational waves is pushing back the frontiers of many fields, from lasers and materials science to high performance computing, and thus provides a powerful showcase for the attractions and challenges of a career in science and engineering. For several years a worldwide network of ground-based laser interferometric gravitational wave detectors, built and run by the LIGO Scientific Collaboration, has been fully operational. These detectors are already among the most sensitive scientific instruments on the planet but in the next few years their sensitivity will achieve further significant improvement. Those developments promise to open an exciting new window on the Universe, heralding the arrival of gravitational wave astronomy as a revolutionary, new observational field. In this poster we describe the extensive program of public outreach activities already undertaken by the LIGO Scientific Collaboration, and a number of special events which we are planning for IYA2009. These activities include: * programs at Science Centers and Observatory Visitor Centers * programs on gravitational wave astronomy for the classroom, across the K-12 spectrum * interdisciplinary events linking gravitational wave astronomy to music and the visual arts * research experiences for schools and citizens through the highly successful `Einstein@Home' program.

    The field of ground-based gamma-ray astronomy has enjoyed rapid growth in recent years. As an increasing number of sources are detected at TeV energies, the field has matured and become a viable branch of modern astronomy. Lying at the uppermost end of the electromagnetic rainbow, TeV photons are always preciously few in number but carry essential information about the particle acceleration and radiative processes involved in extreme astronomical settings. Together with observations at longer wavelengths, TeV gamma-ray observations have drastically improved our view of the universe. In this re-view, we briefly describe recent progress in the field. We will conclude by providing a personal perspective on the future of the field, in particular, on the significant roles that China could play in advancing this young but exciting field.

  11. Astronomy Courses which Emphasize Communication Skills

    Dinerstein, H. L.

    1998-12-01

    The ability to communicate effectively, both in oral and written form, is crucial for success in almost any career path. Furthermore, being able to effectively communicate information requires a high level of conceptual mastery of the material. For these reasons, I have incorporated practice in communication into courses at a variety of levels, ranging from non-science-major undergraduate courses to graduate courses. I briefly describe the content of these courses, particularly the communication-related component. The first, Ast 309N, ``Astronomy Bizarre: Stars and Stellar Evolution," is an elective which follows one semester of general introductory astronomy for non-majors. Instead of homework problems, the students complete a sequence of writing assignments of graduated complexity, beginning with simple tasks such as writing abstracts and critiques of assigned readings, and moving on to writing term papers which require literature research and a short science fiction story incorporating accurate depictions of relativistic effects. In Ast 175/275, a ``Journal Club" course for upper-division astronomy majors, students read articles in the professional literature and give short oral presentations to the rest of the class. To build up their understanding of a topic, we work through the ``paper trail" of key papers on topics with exciting recent developments, such as extrasolar planets, gravitational lenses, or gamma-ray bursts. Finally, in a seminar course for first-semester astronomy graduate students (Ast 185C) that broadly addresses professional development issues, I include a practice AAS oral session, with the students giving 5-minute presentations on a journal paper of their choice. This seminar course also examines career paths and employment trends, the peer review process for papers and proposals, professional norms and ethics, and other topics. Syllabi for these and other courses I teach regularly can be found from my home page (http://www.as.utexas.edu/astronomy/people/dinerstein).

    2007-01-01

    A Kongsberg Simrad EM 3000 multibeam sonar (Kongsberg Simrad, Kongsberg, Norway) was used to conduct a set of six repeat high-resolution bathymetric surveys west of Indian Rocks Beach (IRB), just to the south of Clearwater, FL, between January and March 2003, to observe in situ scour and burial of instrumented inert mines and mine-like cylinders. Three closely located study sites were chosen: two fine-sand sites, a shallow one located in ??? 13 m of water depth and a deep site located in ???14 m of water depth; and a coarse-sand site in ???13 m. Results from these surveys indicate that mines deployed in fine sand are nearly buried within two months of deployment (i.e., they sunk 74.5% or more below the ambient seafloor depth). Mines deployed in coarse sand showed a lesser amount of scour, burying until they present roughly the same hydrodynamic roughness as the surrounding rippled bedforms. These data were also used to test the validity of the Virginia Institute of Marine Science (VIMS, Gloucester Point, VA) 2-D burial model. The model worked well in areas of fine sand, sufficiently predicting burial over the course of the experiment. In the area of coarse sand, the model greatly overpredicted the amount of burial. This is believed to be due to the presence of rippled bedforms around the mines, which affect local bottom morphodynamics and are not accounted for in the model, an issue currently being addressed by the modelers. This paper focuses specifically on two instrumented mines: an acoustic mine located in fine sand and an optical instrumented mine located in coarse sand. ?? 2007 IEEE.

  13. Women in Italian astronomy

    Matteucci, Francesca

    2014-01-01

    This document gives some quantitative facts about the role of women in Italian astronomy. More than 26% of Italian IAU members are women: this is the largest fraction among the world leading countries in astronomy. Most of this high fraction is due to their presence in INAF, where women make up 32% of the research staff (289 out of 908) and 40% of the technical/administrative staff (173 out of 433); the percentage is slightly lower among permanent research staff (180 out of 599, about 30%). The presence of women is lower in the Universities (27 out of 161, about 17%, among staff). In spite of these (mildly) positive facts, we notice that similarly to other countries (e.g. USA and Germany) career prospects for Italian astronomers are clearly worse for women than for men. Within INAF, the fraction of women is about 35-40% among non-permanent position, 36% for Investigators, 17% for Associato/Primo Ricercatore, and only 13% among Ordinario/Dirigente di Ricerca. The situation is even worse at University (only 6% ...

    The Slacker Astronomy podcast is a weekly audio show about astronomy. Available in MP3 format, it is syndicated using RSS and XML feeds that make downloading snap. Each show presents a recent astronomical news item in an entertaining, humorous, and easy-to-understand manner that informs yet respects the intelligence of the listener. First launched on 05 Feb 14, the show has grown to over 5,000 weekly subscribers as of 05 April 01 without any formal publicity. Response has been over overwhelmingly positive, with strong reviews coming from other popular podcasts and coverage on the front page of the MSNBC.com science section. Our only consistent negative feedback is that the show is too short and too infrequent. This demonstrates a strong need to add content. We believe podcasting provides a unique mechanism to extend astronomical outreach to the younger generations and to those who lead busy lifestyles. Our formula is proving successful and we are looking for ways to quantify our impact and measure our demographic so that we can serve them better.

    College-age Haitian students working with advisors and volunteers from UMass Lowell in 2015 developed and tested an activity-based K-8 curriculum in astronomy, space, and earth science. Our partner school is located in Les Cayes, Haiti a city where only 65% of children attend school, and only half of those will complete 6th grade. Astronomy provides an accessible and non-intimidating entry into science, and activity-based learning contrasts with the predominant traditional teaching techniques in use in Haiti, to reach and inspire a different cohort of learners. Teachers are predominantly women in Haiti, so part of the effort involves connecting them with scientists, engineers and teacher peers in the US. As a developing nation, it is vital for Haitian (as for all) children to grow up viewing women as leaders in science. Meanwhile in the US, few are aware of the reality of getting an education in a 3rd world nation (i.e. most of the world), so we also joined with teachers in Massachusetts to give US school children a peek at what daily life is like for their peers living in our vibrant but impoverished neighbor. Our Haitian partners are committed to helping their sister-schools with curriculum and educator workshops, so that the overall quality of education can rise, and not be limited to the very few schools with access to resources. We will describe the activites, motivation, and and the lessons learned from our first year of the project.

    A new semester begins, and your students enter the classroom for the first time. You notice a student sitting in a wheelchair or walking with assistance from a cane. Maybe you see a student with a guide dog or carrying a Braille computer. Another student gestures "hello” but then continues hand motions, and you realize the person is actually signing. You wonder why another student is using an electronic device to speak. Think this can't happen in your class? According to the U.S. Census, one out of every five Americans has a disability. And some disabilities, such as autism, dyslexia and arthritis, are considered "invisible” disabilities. This means you have a high probability that one of your students will have a disability. As an astronomy instructor, you have the opportunity to reach a wide variety of learners by using creative teaching strategies. I will share some suggestions on how to make astronomy and your part of the universe more accessible for everyone.

    observations to produce extremely high-resolution images, and another network (the High Sensitivity Array) that uses the same technique with large telescopes to observe particularly faint celestial objects. With this technique, NRAO telescopes work with MPIfR's Effelsberg telescope to produce images hundreds of times more detailed than those from the Hubble Space Telescope. Both institutions also are part of the international collaboration building the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile and of the international planning effort to build a Square Kilometer Array. The VLBA is a system of ten antennas, each with a dish 25 meters in diameter. From Mauna Kea on the Big Island of Hawaii to St. Croix in the U.S. Virgin Islands, the VLBA spans more than 8000 kilometers. Under the new agreement, the two institutions will continue their previous observational collaborations, and in addition will share resources to improve the technical capabilities of each other's telescopes, particularly at short wavelengths, They also will collaborate in the peer-reviewed process each uses to allocate observing time, and agree to mutually maintain an "open skies" policy allowing open access to each other's telescopes on a peer-reviewed basis. The agreement notes the report of the U.S. National Science Foundation's (NSF) Senior Review committee, which called upon the NRAO to seek partners to contribute to the operation of the VLBA. The MPIfR affirms its strong interest in maintaining the VLBA's unique scientific capabilities, and its monetary contribution toward the 22 GHz upgrade of the VLBA is a solid sign of that commitment. "The VLBA provides the greatest resolving power of any instrument in astronomy, and the MPIfR's contribution to enhancing its capabilities is an important validation of the VLBA's importance to frontier astrophysics," Lo said. The joint VLBA project calls for the MPIfR to fund the receiving-system upgrades and the NRAO to perform the work. The project is

    2015-08-01

    This paper reports the first steps taken in the International STudy on Astronomy Reasoning (iSTAR). The iSTAR Project is an attempt to look beyond traditional wisdom and practices in astronomy education, to discover the ways in which cognitive abilities and human culture interact to impact individuals’ understanding of and relationship to astronomy content knowledge. In contrast to many international studies that seek to rank nations by student performance on standardized tests, the iSTAR Project seeks to find ways that culture may unexpectedly enhance performance in astronomy. Using the Test of Astronomy Standards (TOAST) as a reasonable, initial proxy for the content knowledge a well educated person might know in astronomy, the iSTAR team then defined culture as a construct with five components: practices, traditional knowledge, historical and genealogical relationships, place-based knowledge, and language. Given the complexity of this construct, Stage 1 of the project focuses on the cultural component of language, and assumed that prior to the collection of data from students, the process of translating the TOAST could provide valuable expert-based information on the impact of language on astronomy knowledge. As such, the work began with a study of the translation process. For each of the languages used in the testing phase of the iSTAR protocol, a succession of translators and analysts were engaged, including two educated, non-astronomer native speakers, a native speaking astronomer, and a native speaking linguistics expert. Multiple translations were analyzed in order to make relevant meaning of differences in the translations, and provide commentary on the ways in which metaphor, idiom, cultural history are embedded in the language, providing potential advantages in the learning of astronomy. The first test languages were German, Hawaiian, and American Sign Language, and initial findings suggest that each of these languages provide specific advantages

    The recent observation by the IceCube neutrino observatory of an astrophysical flux of neutrinos represents the "first light" in the nascent field of neutrino astronomy. The observed diffuse neutrino flux seems to suggest a much larger level of hadronic activity in the non-thermal universe than previously thought and suggests a rich discovery potential for a larger neutrino observatory. This document presents a vision for an substantial expansion of the current IceCube detector, IceCube-Gen2, including the aim of instrumenting a $10\\,\\mathrm{km}^3$ volume of clear glacial ice at the South Pole to deliver substantial increases in the astrophysical neutrino sample for all flavors. A detector of this size would have a rich physics program with the goal to resolve the sources of these astrophysical neutrinos, discover GZK neutrinos, and be a leading observatory in future multi-messenger astronomy programs.

    We begin by describing the infrastructure for graduate education and research in astronomy in Canada. We then describe recent and current trends and issues, including facilities, funding, curriculum, and job prospects. This information has been collected through two channels: through graduate coordinators in astronomy departments and groups in Canadian universities, and through the Graduate Student Committee of the Canadian Astronomical Society (CAS). We emphasize the benefits of having a graduate student chapter in societies such as the CAS and the AAS.

    This brief paper introduces and reviews the 'visions of the future' articles prepared by leading young scientists throughout the world for the first of two Christmas 2008 Triennial issues of Phil. Trans. R. Soc. A, devoted, respectively, to astronomy and Earth science. Contributions in astronomy include the very topical gamma-ray bursts, new ideas on stellar collapse and the unusual atmospheres of synchronized planets orbiting nearby stars.

  3. IceCube: An Instrument for Neutrino Astronomy

    2010-06-04

    Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer-scale neutrino detectors were required. The first such instrument, IceCube, is near completion and taking data. The IceCube project transforms a cubic kilometer of deep and ultra-transparent Antarctic ice into a particle detector. A total of 5,160 optical sensors are embedded into a gigaton of Antarctic ice to detect the Cherenkov light emitted by secondary particles produced when neutrinos interact with nuclei in the ice. Each optical sensor is a complete data acquisition system, including a phototube, digitization electronics, control and trigger systems and LEDs for calibration. The light patterns reveal the type (flavor) of neutrino interaction and the energy and direction of the neutrino, making neutrino astronomy possible. The scientific missions of IceCube include such varied tasks as the search for sources of cosmic rays, the observation of Galactic supernova explosions, the search for dark matter, and the study of the neutrinos themselves. These reach energies well beyond those produced with accelerator beams.

    Lubowich, Donald A.

    2009-05-01

    This NASA-funded Music and Astronomy Under the Stars outreach program brings telescopes and astronomy information (via a video display and outdoor exhibit) to community parks during and after music concerts and outdoor family films attended by 500 to 50,000 people. This program will permit the entire community to participate with telescope observations and will enhance the public appreciation of astronomy. The telescopes will be accessible to those with physical disabilities. This program combines music, telescope observations, and astronomy information and targets people who may not attend star parties, planetariums, or science museums. I update this program and discus the lessons learned such as the importance of coordination with local governments, community park districts, and amateur astronomer clubs. This program can be expanded and modified for the local communities. I have expanded this program to large and small venues from New York Philharmonic concert at Heckscher State Park, the boardwalk and a "tail-gate” star party by at pop-music concerts at Jones Beach State Park, and at the Tanglewood Music Festival in Lenox, MA, summer home of the Boston Symphony Orchestra (http://www.bso.org/bso/mods/perf_detail.jsp?pid=prod2880024). This program is expandable to include outdoor dance or theatre programs, festivals in parks or beaches or amusement parks. Music and Astronomy Under the Stars is program that should continue beyond IYA-2009 beaches. Special events such as a Super Bowl Star Party and Halloween Stars will be presented as will the results form NASA-funded hands-on astronomy activities to children and their families receiving medical treatment at the Children's Medical Center at Winthrop University Hospital (Mineola, NY) and the Ronald McDonald House of Long Island (New Hyde Park, NY).

    2006-12-01

    Since 2003 the NASA Center for Astronomy Education (CAE) has been devoted to the professional development of introductory college astronomy faculty with a special focus on faculty teaching at community colleges. As part of our efforts CAE conducts 2-day and 3-day Teaching Excellence Workshops. In Tier I (introductory) Workshops, the overarching goal is for participants to become familiar with learner-centered teaching and assessment materials, as well as how to implement them in their college introductory astronomy courses. To accomplish this goal, participants learn how to create productive learning environments by reviewing research on the nature of teaching and learning; setting course goals and objectives; and using interactive lectures, peer instruction, engaging demonstrations, collaborative groups, tutorials, and ranking tasks. Participants also learn how to create more effective multiple-choice tests. In Tier II (advanced) Workshops, the overarching goal is to help past workshop participants with their obstacles to implementing a learner-centered introductory college astronomy course. Workshop participants work to understand how students learn while engaged in learner-centered activities and what the role of the instructor is in the learner-centered class. CAE regional workshops are held at community colleges around the country, NASA Research Centers, and in conjunction with professional society meetings, such as the American Astronomical Society and the American Association of Physics Teachers, and also through the infrastructure of the National Science Foundation's Summer Chautauqua Workshop program. The NASA Center for Astronomy Education (CAE) is a partnership with the Univ. of Arizona Conceptual Astronomy & Physics Education Research (CAPER) Team. CAE is supported by NASA JPL's Navigator Public Engagement program (consisting of several space telescopes--including SIM PlanetQuest, the Terrestrial Planet Finder, the Keck Interferometer, and the Large

    2006-08-01

    The University of Central Lancashire operates a suite of distance learning courses in Astronomy, available both on-line and via CD-ROM. The courses are available worldwide, and emphasise flexibility of study. To this end students can study anything from a single module (1/6^th of a full year at degree level) all the way up to an entire degree entirely by distance learning. Study rates vary from one to four modules each year, and students can move on to Level 2 modules (equivalent to second year level in a UK degree) before completing the full set of Level 1 modules. Over 1000 awards have been made to date. The core syllabus is Astronomy and Cosmology at Level 1, alongside skills in literature research, using computers, and basic observing. We also offer a basic history of European astronomy. At Level 2 we look at the astrophysics of the Sun, the stars, and galaxies including the Milky Way. By Level 3 students are expected to engage in a large individual project, and a collaborative investigation with other students, alongside high-level courses in cosmology, relativity, extreme states of matter and the origins of the elements, life and astronomical objects. While many students are retired people looking to exercise their brains, keen amateur amateurs or professionals with disposable incomes, and significant fraction are teachers seeking to improve their subject knowledge or high school students gaining an edge in the UK University entrance competition. Via our involvement with SALT we offer our courses to members of previously disadvantaged communities. This leads to an incredibly diverse and lively student body.

  7. Solar Eclipses and the International Year of Astronomy

    Pasachoff, Jay M.

    2009-05-01

    Solar eclipses capture the attention of millions of people in the countries from which they are visible and provide a major opportunity for public education, in addition to the scientific research and student training that they provide. The 2009 International Year of Astronomy began with an annular eclipse visible from Indonesia on 26 January, with partial phases visible also in other parts of southeast Asia. On 22 July, a major and unusually long total solar eclipse will begin at dawn in India and travel across China, with almost six minutes of totality visible near Shanghai and somewhat more visible from Japanese islands and from ships at sea in the Pacific. Partial phases will be visible from most of eastern Asia, from mid-Sumatra and Borneo northward to mid-Siberia. Eclipse activities include many scientific expeditions and much ecotourism to Shanghai, Hangzhou, and vicinity. My review article on "Eclipses as an Astrophysical Laboratory" will appear in Nature as part of their IYA coverage. Our planetarium presented teacher workshops and we made a film about solar research. Several new books about the corona or eclipses are appearing or have appeared. Many articles are appearing in astronomy magazines and other outlets. Eclipse interviews are appearing on the Planetary Society's podcast "365 Days of Astronomy" and on National Geographic Radio. Information about the eclipse and safe observation of the partial phases are available at http://www.eclipses.info, the Website of the International Astronomical Union's Working Group on Solar Eclipses and of its Program Group on Public Education at the Times of Eclipses of its Commission on Education and Development. The Williams College Expedition to the 2009 Eclipse in the mountains near Hangzhou, China, is supported in part by a grant from the Committee for Research and Exploration of the National Geographic Society. E/PO workshops were supported by NASA.

  8. Teaching Advanced Data Analysis Tools to High School Astronomy Students

    Science.gov (United States)

    Black, David V.; Herring, Julie; Hintz, Eric G.

    2015-01-01

    A major barrier to becoming an astronomer is learning how to analyze astronomical data, such as using photometry to compare the brightness of stars. Most fledgling astronomers learn observation, data reduction, and analysis skills through an upper division college class. If the same skills could be taught in an introductory high school astronomy class, then more students would have an opportunity to do authentic science earlier, with implications for how many choose to become astronomers. Several software tools have been developed that can analyze astronomical data ranging from fairly straightforward (AstroImageJ and DS9) to very complex (IRAF and DAOphot). During the summer of 2014, a study was undertaken at Brigham Young University through a Research Experience for Teachers (RET) program to evaluate the effectiveness and ease-of-use of these four software packages. Standard tasks tested included creating a false-color IR image using WISE data in DS9, Adobe Photoshop, and The Gimp; a multi-aperture analyses of variable stars over time using AstroImageJ; creating Spectral Energy Distributions (SEDs) of stars using photometry at multiple wavelengths in AstroImageJ and DS9; and color-magnitude and hydrogen alpha index diagrams for open star clusters using IRAF and DAOphot. Tutorials were then written and combined with screen captures to teach high school astronomy students at Walden School of Liberal Arts in Provo, UT how to perform these same tasks. They analyzed image data using the four software packages, imported it into Microsoft Excel, and created charts using images from BYU's 36-inch telescope at their West Mountain Observatory. The students' attempts to complete these tasks were observed, mentoring was provided, and the students then reported on their experience through a self-reflection essay and concept test. Results indicate that high school astronomy students can successfully complete professional-level astronomy data analyses when given detailed

    Science.gov (United States)

    Slater, Timothy F.

    2015-08-01

    Filling a needed scholarly publishing avenue for astronomy education researchers and earth science education researchers, the Journal of Astronomy & Earth Sciences Education- JAESE was first published in 2014. JAESE is a scholarly, peer-reviewed scientific journal publishing original discipline-based education research and evaluation, with an emphasis of significant scientific results derived from ethical observations and systematic experimentation in science education and evaluation. International in scope, JAESE aims to publish the highest quality and timely articles from discipline-based education research that advance understanding of astronomy and earth sciences education and are likely to have a significant impact on the discipline or on policy. Articles are solicited describing both (i) systematic science education research and (ii) evaluated teaching innovations across the broadly defined Earth & space sciences education, including the disciplines of astronomy, climate education, energy resource science, environmental science, geology, geography, agriculture, meteorology, planetary sciences, and oceanography education. The publishing model adopted for this new journal is open-access and articles appear online in GoogleScholar, ERIC, EBSCO, ProQuest, and NASA SAO/ADS and are searchable in catalogs of 440,000 libraries that index online journals of its type. Rather than paid for by library subscriptions or by society membership dues, the annual budget is covered by page-charges paid by individual authors, their institutions, grants or donors: This approach is common in scientific journals, but is relatively uncommon in education journals. Authors retain their own copyright. The journal is owned by the Clute Institute in the United States, which owns and operates 17 scholarly journals and currently edited by former American Astronomical Society Education Officer Tim Slater, who is an endowed professor at the University of Wyoming and a Senior Scientist at the

    Gauthier, Adrienne J.; Huber, D.; I. New Media Task Group

    2009-01-01

    The NMTG has created an IYA 2009 presence in the 3-dimensional multi-user virtual world called Second Life (R), where residents (or avatars) interact with content built by others in dynamic, innovative, and social ways. The IYA2009 virtual real estate (called an island) will open in early January 2009 with an initial set of exhibits and interactives. Through 2009, additional exhibits, live talks, and webstreamed content will be added.Our Sidewalk Astronomy experience will be premiered for the island opening. We have designed the interactive to replicate a real-life small telescope experience. Visitors to our Second Life telescopes will first see an image of the object "as the eye sees" and will hear/read a narrative about the object, as one would experience in real life. The narratives have been carefully crafted to take the observer on a journey and not just hear straight facts about the object. Diving further into astronomical imagery, avatars will explore visible, infrared, X-ray, and radio views of the object (if available), all wrapped in contextual information that ties the multiwavelength views together. The content of the telescopes will update every month to be equivalent to mid-latitude 9pm sky views for the Northern Hemisphere, Southern Hemisphere pending. Supplemental materials will include World Wide Telescope tours and Google Sky layers. We are hoping to add live star party events throughout the year, using real life video feeds from amateur telescopes. Additionally, we will have links to the Sidewalk Astronomy IYA webpage so virtual residents can find real life star parties to attend. The Sidewalk Astronomy Second Life experience will also have a traveling version that can be placed in multiple locations (stores, events, parks) in order to bring astronomy to the virtual masses in a true Sidewalk Astronomy way.

  13. A New Resource for College Distance Education Astronomy Laboratory Exercises

    CERN Document Server

    Vogt, Nicole P; Muise, Amy Smith

    2015-01-01

    This article introduces a set of distance education astronomy laboratory exercises for use by college students and instructors and discuss first usage results. This General Astronomy Education Source (GEAS) exercise set contains eight two-week projects designed to guide students through both core content and mathematical applications of general astronomy material. Projects are divided between hands-on activities and computer-aided analyses of modern astronomical data. The suite of online resources includes student and instructor guides, laboratory report templates, learning objectives, video tutorials, plotting tools, and web-based applications that allow students to analyze both images and spectra of astronomical objects. A pilot usage study indicates that distance learners using these materials perform as well or better than a comparison cohort of on-campus students. We are actively seeking collaborators to use these resources in astronomy courses and other educational venues.

    2016-10-01

    At the 2012 General Assembly of the International Astronomical Union (IAU), the Office of Astronomy for Development announced a number of exciting new partnerships to assist with the IAU's decadal strategic plan (2010-2020). These landmark decisions included establishing a new coordinating centre that aims at using astronomy as a tool for development in East Asia. The agreement covers two important functions. One is known as a Regional Node, which entails the coordination of astronomy-for-development activities in countries within the general geographical region of East Asia. The other is known as a Language Expertise Centre which deals with all aspects relating to (mainly) the Chinese language and culture. The impact of the latter may obviously spread well beyond the geographical region to other parts of the world. Here we provide an update of the achievements and aims of the East Asian Office of Astronomy for Development.

    2016-12-01

    Although astronomy is considered one of the older sciences of mankind, its teaching in basic education is facing problems. It is the school responsibility the dissemination of correct scientific concepts, including those related to Astronomy. This study was conducted at the Federal Institute of Education, Science and Technology of Santa Catarina, Campus Araranguá. In this article, we aimed to present the activities developed to help the formation of teachers, training undergraduate students in Natural Sciences with specialization in Physics to contribute to the dissemination and improvement of the teaching-learning of Astronomy. This paper presents the process and results of the evaluation of that training program. Analyses of the activity from the perspective of the participants are indicated and additional considerations are made regarding its use as a resource for teaching Astronomy and for teacher training.

  16. Enhancing the Teaching of Astronomy with Science Fiction

    Science.gov (United States)

    Fraknoi, A.

    2004-12-01

    Dozens of scientists and science educators with advanced degrees in science have been writing literate and scientifically reasonable science fiction stories in the last two decades, although these are often drowned out by the din of popular magic teenagers and space battle epics. The paper will give examples of stories and novels with good science, which can be used as a way of making astronomy concepts "come alive" for non-science majors. A list of science fiction authors with astronomy and physics degrees will be included. We will also have examples from a web-site devoted to astronomy in science fiction (see link) that has some 200 brief reviews of stories organized by 40 astronomy topics. We will discuss how instructors are using such stories for classroom and homework assignments.

    2016-01-01

    In the past year, the LIGO-Virgo Collaboration announced the first secure detection of gravitational waves. This discovery heralds the beginning of gravitational wave astronomy: the use of gravitational waves as a tool for studying the dense and dynamical universe. In this talk, I will describe the full spectrum of gravitational waves, from Hubble-scale modes, through waves with periods of years, hours and milliseconds. I will describe the different techniques one uses to measure the waves in these bands, current and planned facilities for implementing these techniques, and the broad range of sources which produce the radiation. I will discuss what we might expect to learn as more events and sources are measured, and as this field matures into a standard part of the astronomical milieu.

  18. Ancient Hawaiian Astronomy

    Science.gov (United States)

    Ruggles, Clive L. N.

    The Hawaiian Islands provide a cultural setting where the prominent place of astronomy within religious, navigational, and calendrical traditions is evident from a rich ethnohistoric record. The many hundreds of temple platforms and enclosures (heiau) whose remains survive across the archipelago have provided a natural focus for archaeoastronomers not only to examine orientations and structural alignments but to explore a range of issues relating to field method and practice in a context where spatially patterned archaeological data and ethnohistorical evidence exist in relatively fine balance. As archaeoastronomy has developed within the islands, it has become better integrated into archaeological investigations tackling questions of broader anthropological significance, one of the most fascinating being when, how, and why Polynesian chiefdoms became transformed into archaic states, something that happened here but nowhere else in Polynesia.

    Astronomy For Beginners is a friendly and accessible guide to our universe, our galaxy, our solar system and the planet we call home. Each year as we cruise through space on this tiny blue-green wonder, a number of amazing and remarkable events occur. For example, like clockwork, we'll run head-on into asteroid and cometary debris that spreads shooting stars across our skies. On occasion, we'll get to watch the disk of the Moon passing the Sun, casting its shadow on the face of the Earth, and sometimes we'll get to watch our own shadow as it glides across the face of the Moon.

    2012-01-01

    The gravitational wave window onto the universe will open in roughly five years, when Advanced LIGO and Virgo achieve the first detections of high frequency gravitational waves, most likely coming from compact binary mergers. Electromagnetic follow-up of these triggers, using radio, optical, and high energy telescopes, promises exciting opportunities in multi-messenger time domain astronomy. In the decade, space-based observations of low frequency gravitational waves from massive black hole mergers, and their electromagnetic counterparts, will open up further vistas for discovery. This two-part workshop featured brief presentations and stimulating discussions on the challenges and opportunities presented by gravitational wave astronomy. Highlights from the workshop, with the emphasis on strategies for electromagnetic follow-up, are presented in this report.

  1. Astronomy Outreach Adventures in Rural Guatemala

    Strubbe, L.

    2015-03-01

    Astronomy can be an inspirational gateway to learning science and analytical reasoning, and to careers in STEM fields-particularly important in developing countries where educational opportunities can be scarce. Following this idea and my interest in learning about other cultures, I decided to spend 6 weeks in late 2011 (between Ph.D. and postdoc) doing astronomy public outreach in Guatemala. I volunteered through a Spanish language school embedded in a poor rural community (typical earning ~ $3/day), working mostly with children. My teaching goals were primarily attitudinal: to encourage people to observe and ask questions about the world around them, and to show them that phenomena have explanations that we can understand.

  3. Alaska Athabascan stellar astronomy

    Science.gov (United States)

    Cannon, Christopher M.

    2014-01-01

    Stellar astronomy is a fundamental component of Alaska Athabascan cultures that facilitates time-reckoning, navigation, weather forecasting, and cosmology. Evidence from the linguistic record suggests that a group of stars corresponding to the Big Dipper is the only widely attested constellation across the Northern Athabascan languages. However, instruction from expert Athabascan consultants shows that the correlation of these names with the Big Dipper is only partial. In Alaska Gwich'in, Ahtna, and Upper Tanana languages the Big Dipper is identified as one part of a much larger circumpolar humanoid constellation that spans more than 133 degrees across the sky. The Big Dipper is identified as a tail, while the other remaining asterisms within the humanoid constellation are named using other body part terms. The concept of a whole-sky humanoid constellation provides a single unifying system for mapping the night sky, and the reliance on body-part metaphors renders the system highly mnemonic. By recognizing one part of the constellation the stargazer is immediately able to identify the remaining parts based on an existing mental map of the human body. The circumpolar position of a whole-sky constellation yields a highly functional system that facilitates both navigation and time-reckoning in the subarctic. Northern Athabascan astronomy is not only much richer than previously described; it also provides evidence for a completely novel and previously undocumented way of conceptualizing the sky---one that is unique to the subarctic and uniquely adapted to northern cultures. The concept of a large humanoid constellation may be widespread across the entire subarctic and have great antiquity. In addition, the use of cognate body part terms describing asterisms within humanoid constellations is similarly found in Navajo, suggesting a common ancestor from which Northern and Southern Athabascan stellar naming strategies derived.

    On November 9th, 2015, three didactical hours were dedicated to Interdisciplinary Astronomy Activities (http://wp.me/p6Hte2-1I). Our students and their teachers formed three groups and in rotation, were engaged with the following activities: (a) viewing unique images of the Cosmos in the mobile planetarium STARLAB (http://www.planitario.gr/tholos-starlab-classic-standard.html), (b) watching the following videos: Journey to the end of the universe (https://youtu.be/Ufl_Nwbl8xs), Rosetta update (https://youtu.be/nQ9ivd7wv30), The Solar System (https://youtu.be/d66dsagrTa0), Ambition the film (https://youtu.be/H08tGjXNHO4) in the school's library. Students and teachers were informed about our solar system, the Rosetta mission, the universe, etc. and (c) tactile activities such as Meet our home and Meet our neighbors (http://astroedu.iau.org, http://nuclio.org/astroneighbours/resources) and the creation of planets' 3D models (Geology-Geography A' Class Student's book, pg.15). With the activities above we had the pleasure to join the Cosmic Light Edu Kit / International Year of Light 2015 program. After our Interdisciplinary Astronomy Activities, we did a "small" research: our students had to fill an evaluation about their educational gains and the results can be found here http://wp.me/p6Hte2-2q. Moreover, we discussed about Big Ideas of Science (http://wp.me/p3oRiZ-dm) and through the "big" impact of the Rosetta mission & the infinity of our universe, we print posters with relevant topics and place them to the classrooms. We thank Rosa Doran (Nuclio - President of the Executive Council) for her continuous assistance and support on innovative science teaching proposals. She is an inspiration.

  5. Worldwide site comparison for submillimetre astronomy

    Tremblin, P; Minier, V; Durand, G Al; Urban, J

    2012-01-01

    The most important limitation for ground-based submillimetre (submm) astronomy is the broad-band absorption of the total water vapour in the atmosphere above an observation site, often expressed as the Precipitable Water Vapour (PWV). A long-term statistic on the PWV is thus mandatory to characterize the quality of an existing or potential site for observational submm-astronomy. In this study we present a three-year statistic (2008-2010) of the PWV for ground-based telescope sites all around the world and for stratospheric altitudes relevant for SOFIA (Stratospheric Observatory for Far-infrared astronomy). The submm-transmission is calculated for typical PWVs using an atmospheric model. We present the absolute PWV values for each site sorted by year and time percentage. The PWV corresponding to the first decile (10%) and the quartiles (25%, 50%, 75%) are calculated and transmission curves between 150 {\\mu}m and 3 mm for these values are shown. The Antarctic and South-American sites present very good condition...

    2008-11-01

    This is a summary of our 90-minute International Year of Astronomy (IYA) symposium workshop about engaging greater public interest in astronomy during the International Year of Astronomy 2009 through art and music. The session focused on: (i) plans for visually interesting and challenging astronomy presentations to connect with an audience at venues such as museums, concert halls, etc that might be apprehensive about science but open to creative experiences; (ii) the nuts-and-bolts of turning creative ideas into exhibits or visualizations; (iii) balancing scientific accuracy with artistic license; and (iv) how scientists, Education and Public Outreach (EPO) professionals, artists, musicians et al. can bridge the ``two cultures''---starting and sustaining multi-disciplinary collaborations, articulating expectations, and building synergy. The presenters shared with the EPO community some of the astronomy-art projects and resources that we have been developing for the IYA through a variety of collaborations. Our portfolios include state-of-the-art astronomy visualizations and tools, music videos and podcasts that highlight stunning images from NASA's Great Observatories; a video suite of astronomical images that can accompany live performances of Holst's The Planets and Mussorgsky's Pictures at an Exhibition; and SCALE, a multicomponent traveling art installation including the largest pastel drawing of the Milky Way.

    2015-08-01

    It is astronomers’ duty to let more and more young people know a bit astronomy and be interested in astronomy and appreciate the beauty and great achievements in astronomy. One of the most effective methods to popularize astronomy to young people nowadays might be via enjoying some brilliant sci-fi movies related to astronomy with some guidance from astronomers. Firstly, we will introduce the basic information of our selective course “Appreciation of Sci-fi Movies in Astronomy” for the non-major astronomy students in our University, which is surely unique in China, then we will show its effect on astronomy popularization based on several rounds of teaching.

  8. A Review of Astronomy Education Research

    Bailey, Janelle M.; Slater, Timothy F.

    The field of astronomy education is rapidly growing beyond merely sharing effective activities or curriculum ideas. This paper categorizes and summarizes the literature in astronomy education research and contains more than 100 references to articles, books, and Web-based materials. Research into student understanding on a variety of topics now occupies a large part of the literature. Topics include the shape of Earth and gravity, lunar phases, seasons, astrobiology, and cosmology. The effectiveness of instructional methods is now being tested systematically, taking data beyond the anecdotal with powerful research designs and statistical analyses. Quantitative, qualitative, and mixed-methods approaches have found their places in the researcher's toolbox. In all cases, the connection between the research performed and its effect on classroom instruction is largely lacking.

  9. Data Mining and Machine Learning in Astronomy

    CERN Document Server

    Ball, Nicholas M

    2009-01-01

    We review the current state of data mining and machine learning in Astronomy. 'Data Mining' can have a somewhat mixed connotation from the point of view of a researcher in this field. On the one hand, it is a powerful approach, holding the potential to fully exploit the exponentially increasing amount of available data, which promises almost limitless scientific advances. On the other, it can be the application of black-box computing algorithms that at best give little physical insight, and at worst provide questionable results. Here, we give an overview of the entire data mining process, from data collection through the interpretation of results. We cover common machine learning algorithms, such as artificial neural networks and support vector machines; applications from a broad range of Astronomy, with an emphasis on those where data mining resulted in improved physical insights, and important current and future directions, including the construction of full probability density functions, parallel algorithm...

    Hintz, Eric G.; Moody, J. W.; Joner, M. D.; Stephens, D. C.

    2009-01-01

    We have designed an undergraduate astronomy major at BYU which makes astronomical research the focus of the program. The major requires a research focused class (Phscs 329) which teaches students how to take data at the telescope, reduce the data, and present the data. The students must present their results in the format used to submit manuscripts to journals (AASTeX) and as a meeting poster. Finally the class works together to prepare a real telescope proposal that is actually submitted. Majors must then take part in faculty mentored research leading to a senior thesis. At all levels the data produced is of such quality as to generate referred publications in astronomy journals. As an extention of our major we have designed observing projects for our descriptive astronomy class that allow the non-majors a chance to see how astronomers learn the concepts that are taught. The projects range from taking data to create a 3-color image to working with astronomy majors to acquire research quality data.

The result of combining two such motions is then shown to be close to Ptolemy's planetary model. This book provides a fascinating look at the night sky and the techniques that early civilizations, particularly Babylonian and Greek, used to model planetary motions¿Aaboe does a masterful job of covering a wide array of intriguing topics in a relatively short book, and any effort expended on reading it will be well rewarded¿ talented students at the high school age and college students who are interested in these topics would likely find this book very enjoyable and enriching¿Overall, the book is fascinating to read for several reasons, including its observational astronomical viewpoint, its rich historical and cultural content, and, of course, its exposition and explanation of ancient techniques of celestial predictions and modeling. ?MAA ONLINE

  13. Europe Unveils 20-Year Plan for Brilliant Future in Astronomy

    Science.gov (United States)

    2008-11-01

    for Earth Sciences and Astronomy (INSU) of the CNRS. To build consensus on priorities in a very diverse community, the Science Vision and Roadmap were developed in an open process involving intensive interaction with the community through large open meetings and feedback via e-mail and the web. The result is a plan now backed by astronomers in 28 Member and Associated States of the EU, with over 500 million inhabitants. Over 60 selected experts from across Europe contributed to the construction of the ASTRONET Roadmap, ensuring that European astronomy has the tools to compete successfully in answering the challenges of the Science Vision. They identified and prioritised a set of new facilities to observe the Universe from radio waves to gamma rays, to open up new ways of probing the cosmos, such as gravitational waves, and to advance in the exploration of our Solar System. In the process, they considered all the elements needed by a successful scientific enterprise, from global-scale cooperation on the largest mega-project to the need for training and recruiting skilled young scientists and engineers. One of two top-priority large ground-based projects is ESO's European Extremely Large Telescope. Its 42-metre diameter mirror will make the E-ELT the largest optical/near-infrared telescope in the world -- "the biggest eye on the sky". The science to be done with the E-ELT is extremely exciting and includes studies of exoplanets and discs, galaxy formation and dark energy. ESO Director General Tim de Zeeuw says: "The top ranking of the E-ELT in the Roadmap is a strong endorsement from the European astronomical community. This flagship project will indisputably raise the European scientific, technological and industrial profile". Among other recommendations, the Roadmap considers how to maximise the future scientific impact of existing facilities in a cost-effective manner. It also identifies a need for better access to state-of-the art computing and laboratory facilities

    Here we report on the Women in Astronomy Workshop (http://asawomeninastronomy.org/meetings/wia2011/), which was held on 13 May 2011 in Sydney, Australia. The workshop was organised by the Astronomical Society of Australia's Chapter on Women in Astronomy, to discuss some of the issues that face women in astronomy and make recommendations to help support the success of women in Australian astronomy but came to broader conclusions that have value for the whole astronomical community. The workshop consisted of four sessions, with presentations by invited speakers on demographics, leadership, varied career paths, and how institutions & individuals can help. The workshop ended with a discussion panel that summarised the day's debate and presented a list of recommendations for the Australian astronomical community (both individuals and institutions) that are provided in this report.

    Most students entering our introductory astronomy course for nonscience majors arrive not merely lacking scientific facts-they also have misconceptions about the nature of science, and many have a handicapping ``science anxiety'' (in addition to math anxiety). So I have added a ``current science'' requirement to our introductory course. Each student must compile a file of five astronomy news articles taken from readily available sources.

    George, Martin; Orchiston, Wayne; Slee, Bruce; Wielebinski, Richard

    2015-03-01

    Significant contributions to low frequency radio astronomy were made in the Australian state of Tasmania after the arrival of Grote Reber in 1954. Initially, Reber teamed with Graeme Ellis, who was then working with the Ionospheric Prediction Service, and they carried out observations as low as 0.52 MHz during the 1955 period of exceptionally low sunspot activity. In the early 1960s, Reber established a 2.085 MHz array in the southern central region of the State and used this to make the first map of the southern sky at this frequency. In addition, in the 1960s the University of Tasmania constructed several low frequency arrays near Hobart, including a 609m × 609m array designed for operation between about 2 MHz and 20 MHz. In this paper we present an overview of the history of low frequency radio astronomy in Tasmania.

    2015-08-01

    I will present the status of astronomy in educational system in Slovenia. In primary schools astronomy is offered as an optional course in the last 3 grades (12-15 yrs old), while in secondary schools a few astronomical topics are present only as part of other subjects (e.g. physics, geography). I will describe a pilot project of an astronomy course in secondary schools, which was carried out in the school year 2013/14. The main focus of my presentation will be the experience gained with organisation of the Slovenian National Astronomy Competition. It is organised by the Slovenian Society of Mathematicians, Physicists and Astronomers since 2009, building on an extensive network of over 200 primary and secondary school teachers who participated in IYA2009 activities, and who now represent majority of mentors for the competition. In 2013, only 5 years after the start of competition, our pupils attended the International Olympiad on Astronomy and Astrophysics for the first time and with great success. Supporting activities include the Slovenian version of the Portal to the Universe (www.portalvvesolje.si) and translation of Space Scoop astronomy news for children.

  3. The European Association for Astronomy Education

    Reichen, M.

    2006-06-01

    The still very young EAAE (officially founded in November 1995) is an association grouping astronomy minded "educators" (teachers, professional and amateur astronomers, etc.) whose main goal is the development of the place and role of astronomy teaching at various educational levels. An executive council of nine persons is in charge of the large-scale cohesion of the association, while two standing committees (financial support, communication network) and seven working groups (astronomical concepts, didactic materials, training of teachers, student projects, planetarium links, research on teaching materials, and public education) form the structure through which each member can contribute to the association's actions. Each one of these groups is "multi-national" (members come from over twenty countries in Europe and elsewhere), and thus the adopted structure favors the emergence of an international network of teachers, one of the EAAE's primary concerns. Different projects have been achieved or are on the way of achievement (such as the AOL "astronomy on line," the set up of a summer school for teachers, simultaneous observations of solar and lunar eclipses by students all over Europe, development and testing of didactic material, etc.) partially showing the great educational potential of the EAAE.

    Variable Star Network (VSNET) is a global professional-amateur network of researchers in variable stars and related objects, particularly in transient objects, such as cataclysmic variables, black-hole binaries, supernovae, and gamma-ray bursts. The VSNET has been playing a pioneering role in establishing the field of transient object astronomy, by effectively incorporating modern advances in observational astronomy and global electronic networks, as well as collaborative progress in theoretical astronomy and astronomical computing. The VSNET is now one of the best-featured global networks in this field of astronomy. We review the historical progress, design concept, associated technology, and a wealth of scientific achievements powered by VSNET.

  5. A Grand Vision for European Astronomy

    2007-09-01

    Today, and for the first time, astronomers share their global Science Vision for European Astronomy in the next two decades. This two-year long effort by the ASTRONET network of funding agencies, sponsored by the European Commission and coordinated by INSU-CNRS, underscores Europe's ascension to world leadership in astronomy and its will to maintain that position. It will be followed in just over a year by a prioritised roadmap for the observational facilities needed to implement the Vision. Implementation of these plans will ensure that Europe fully contributes to Mankind's ever deeper understanding of the wonders of our Universe. astronet logo "This is a great opportunity to help create a vibrant long-term future for astronomy and science" says Tim de Zeeuw (Leiden Observatory, The Netherlands) who led this community-wide effort. The ASTRONET Science Vision provides a comprehensive overview of the most important scientific questions that European astronomy should address in the next twenty years. The four key questions are the extremes of the Universe, from the nature of the dark matter and dark energy that comprise over 95% of the Universe to the physics of extreme objects such as black holes, neutron stars, and gamma-ray bursts; the formation of galaxies from the first seeds to our Milky Way; the formation of stars and planets and the origin of life; and the crucial question of how do we (and our Solar System) fit in the global picture. These themes reach well beyond the realm of traditional astronomy into the frontiers of physics and biology. The Vision identifies the major new facilities that will be needed to achieve these goals, but also stresses the need for parallel developments in theory and numerical simulations, high-performance computing resources, efficient astronomical data archiving and the European Virtual Observatory, as well as in laboratory astrophysics. "This report is a key input for the even more challenging task of developing a prioritised

    Szalay, Alexander S.; Gray, Jim; Kunszt, Peter; Thakar, Anirudha; Slutz, Don

    The next-generation astronomy digital archives will cover most of the sky at fine resolution in many wavelengths, from X-rays through ultraviolet, optical, and infrared. The archives will be stored at diverse geographical locations. The intensive use of advanced data archives will enable astronomers to explore their data interactively. Data access will be aided by multidimensional spatial and attribute indices. The data will be partitioned in many ways. Small tag indices consisting of the most popular attributes will accelerate frequent searches. Splitting the data among multiple servers will allow parallel, scalable I/O and parallel data analysis. Hashing techniques will allow efficient clustering, and pair-wise comparison algorithms that should parallelize nicely. Randomly sampled subsets will allow debugging otherwise large queries at the desktop. Central servers will operate a data pump to support sweep searches touching most of the data. The anticipated queries will require special operators related to angular distances and complex similarity tests of object properties, like shapes, colors, velocity vectors, or temporal behaviors. These issues pose interesting data management challenges.

  8. Astronomy in India a historical perspective

    CERN Document Server

    2014-01-01

    India has a strong and ancient tradition of astronomy, which seamlessly merges with the current activities in Astronomy and Astrophysics in the country. While the younger generation of astronomers and students are reasonably familiar with the current facilities and the astronomical research, they might not have an equally good knowledge of the rich history of Indian astronomy. This particular volume, brought out as a part of the Platinum Jubilee Celebrations of Indian National Science Academy, concentrates on selected aspects of historical development of Indian astronomy in the form of six invited chapters. Two of the chapters – by Balachandra Rao and M.S. Sriram – cover ancient astronomy and the development of calculus in the ancient Kerela text Yuktibhasa. The other four chapters by B.V. Sreekantan, Siraj Hasan, Govind Swarup and Jayant Narlikar deal with the contemporary history of Indian astronomy covering space astronomy, optical astronomy, radio astronomy and developments in relativistic astrophysic...

    A new Astronomy for Development hub needs innovative tools and programs. SAROAD is developing exciting tools integrating Raspberry Pi® technology to bring cost-effective astronomy content to learning centres. SAROAD would also like to report achievements in realising the IAU's strategic plan. In order to manage, evaluate and coordinate regional IAU capacity building programmes, including the recruitment and mobilisation of volunteers, SAROAD has built an intranet that is accessible to regional members upon request. Using this resource, regional members can see and participate in regional activities. This resource also forms the foundation for closer collaboration between SAROAD member countries. SAROAD has commenced with projects in the three Task Force areas of Universities and Research, Children and Schools and Public Outreach. Under the three Task Force areas, a total of seven projects have commenced in Zambia. A further two projects involve the collaboration of Zambia and other regional member countries in order to foster engagement with important regional astronomy facilities (e.g. SKA). SAROAD has identified the IAU’s International Year of Light and a starting point for offering regional support for IAU-endorsed global activities. SAROAD has set up a hub dedicated to regional events and activities about the International Year of Light. SAROAD has a database of regional authorities to enable contact with the region's decision makers and experts. SAROAD will hold an annual event which brings forum for astronomy for development. The creation of the database and the SAROAD Road show is a first step towards this goal. The SAROAD website has helped to advertise upcoming events for astronomy development and education; it is used to provide advice, guidance and information for astronomers in all countries in the Southern Africa. Fundraising is the primary goal for SAROAD in 2015 towards financial self-sufficiency by 2020. We report on the methods that work best

    The AAS is sponsoring the development of a digital collection of online resources for teaching introductory astronomy: astronomycenter.org. Astronomy Center is part of the ComPADRE project with the AIP and its member organizations (see Deustua et al. at this meeting). The goal of Astronomy Center is to build a portal that will be a broad collection of high-quality digital resources, a useful and inviting interface to search and browse the collection, and an online meeting place for faculty at a variety of institutions to gather and share information. The collection will be launched in early 2005 and will initially contain a few hundred resources, selected primarily by Astronomy Center staff. The collection will grow through user and author submissions. Meanwhile, resources will be peer-reviewed and featured on the site as the collection grows. We will present the astronomycenter.org site, the user interface, some resources in the collection, the peer review process, and how members of the community can get involved with Astronomy Center. This work was made possible by a NSF National Science, Technology, Engineering and Mathematics Digital Library (NSDL) grant to the AAPT, AIP, and AAS.

  11. Curricular Derivatives in Undergraduate Astronomy

    Science.gov (United States)

    Erickson, L. K.

    2002-12-01

    With faculty positions becoming increasingly competitive, the smaller or specialized universities and colleges have become more attractive to the new Ph.D. graduate and post-doc interested in a career in teaching and research. However, the limitations of smaller research resources, and a more limited curricula, and higher teaching loads can make the smaller school less attractive and the position challenging. Nevertheless, smaller institutions can offer greater flexibility in educational innovation, including unique curricula, than larger schools with inherently greater administrative mass. Even without astronomy degree programs or without substantial research facilities, the smaller, private or specialized school environment can provide opportunities to develop courses tailored to the strengths of the school, and to student interests, and more importantly, to the energetic efforts of junior faculty. The author's advocacy for and development of new curricula at a small institution are presented, along with several descriptive examples. Unique aspects of these courses are also characterized in their suitability for research projects, educational outreach and other applications.

    Pilachowski, Catherine A.; van Zee, Liese

    2017-01-01

    The Art of Astronomy is a new general education course developed at Indiana University. The topic appeals to a broad range of undergraduates and the course gives students the tools to understand and appreciate astronomical images in a new way. The course explores the science of imaging the universe and the technology that makes the images possible. Topics include the night sky, telescopes and cameras, light and color, and the science behind the images. Coloring the Universe: An Insider's Look at Making Spectacular Images of Space" by T. A. Rector, K. Arcand, and M. Watzke serves as the basic text for the course, supplemented by readings from the web. Through the course, students participate in exploration activities designed to help them first to understand astronomy images, and then to create them. Learning goals include an understanding of scientific inquiry, an understanding of the basics of imaging science as applied in astronomy, a knowledge of the electromagnetic spectrum and how observations at different wavelengths inform us about different environments in the universe, and an ability to interpret astronomical images to learn about the universe and to model and understand the physical world.

    The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7-m telescope, flying at altitudes as high as 13.7 km (45,000 ft). Designed to observe at wavelengths from 0.3 micron to 1.6 mm, SOFIA operates above 99.8 % of the water vapor that obscures much of the infrared and submillimeter. SOFIA has seven science instruments under development, including an occultation photometer, near-, mid-, and far-infrared cameras, infrared spectrometers, and heterodyne receivers. SOFIA, a joint project between NASA and the German Aerospace Center DLR, began initial science flights in 2010 December, and has conducted 30 science flights in the subsequent year. During this early science period three instruments have flown: the mid-infrared camera FORCAST, the heterodyne spectrometer GREAT, and the occultation photometer HIPO. This article provides an overview of the observatory and its early performance.

  14. Kantian epistemology as an alternative to heroic astronomy

    Science.gov (United States)

    Mclaughlin, W. I.

    1985-01-01

    Theoretical and observational methods in astronomy have advanced to a point where certain of their outcomes are difficult to comprehend with the traditional categories of human knowledge. The philosophical discipline of epistemology, the theory of knowledge, is used here to address four current problems in observational astronomy, exobiology, cosmology, and quantum mechanics. The problems are united by an epistemological content which, when unrecognized, has resulted in some heroic solutions of an ad hoc nature. Kant's critical philosophy is employed because his work is consistent with basic attitudes in present-day physics and biology.

    [figure removed for brevity, see original site] Click on the image for larger version In 1609, Galileo improved the newly invented telescope, turned it toward the heavens, and revolutionized our view of the universe. In celebration of the 400th anniversary of this milestone, 2009 has been designated as the International Year of Astronomy. Today, NASA's Great Observatories are continuing Galileo's legacy with stunning images and breakthrough science from the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory. While Galileo observed the sky using visible light seen by the human eye, technology now allows us to observe in many wavelengths, including Spitzer's infrared view and Chandra's view in X-rays. Each wavelength region shows different aspects of celestial objects and often reveals new objects that could not otherwise be studied. This image of the spiral galaxy Messier 101 is a composite of views from Spitzer, Hubble, and Chandra. The red color shows Spitzer's view in infrared light. It highlights the heat emitted by dust lanes in the galaxy where stars can form. The yellow color is Hubble's view in visible light. Most of this light comes from stars, and they trace the same spiral structure as the dust lanes. The blue color shows Chandra's view in X-ray light. Sources of X-rays include million-degree gas, exploded stars, and material colliding around black holes. Such composite images allow astronomers to see how features seen in one wavelength match up with those seen in another wavelength. It's like seeing with a camera, night vision goggles, and X-ray vision all at once. In the four centuries since Galileo, astronomy has changed dramatically. Yet our curiosity and quest for knowledge remain the same. So, too, does our wonder at the splendor of the universe.

  19. Data in Astronomy

    Science.gov (United States)

    Jaschek, Carlos

    1989-03-01

    This unique handbook explains how astronomical data of all kinds should be obtained, compiled, and published if it is to be used to the best advantage by professional astronomers worldwide. Introductory chapters explain how observations are obtained, discuss observatories, and deal with data generally. The central part of the book explains how data are archived and how they should be presented for later use. One chapter raised the important issue of the designation, or naming, of astronomical objects, since this is a topic where confusion is manifest. A further chapter is devoted to astronomical catalogs and the information available from them, and this introduces data bases, data networks, and data centers. The final chapters address general questions of scientific information, including publication, the use of published data, and the role of international organizations handling data.

    The South African Astronomical Observatory (SAAO) observing station near Sutherland, Northern Cape in South Africa, is one of the darkest sites in the world for optical and IR astronomy. The SAAO hosts and operates several facilities, including the Southern African Large Telescope (SALT) and a number of international robotic telescopes. To ensure that the conditions remain optimal for astronomy, legislation called the Astronomy Geographic Advantage (AGA) Act, of 2007, was enacted. The Act empowers the Department of Science and Technology (DST) to regulate issues that pose a threat to optical and/or radio astronomy in areas declared Astronomy Advantage Areas in South Africa. For optical astronomy, the main challenges are those posed by light and dust pollution as result of wind energy developments, and petroleum gas and oil exploration/exploitation in the area. We give an update of possible threats to the quality of the night skies at SAAO, and the challenges relating to the AGA Act implementation and enforcement. We discuss measures that are put in place to protect the Observatory, including a study to quantify the threat by a planned wind energy facility.

    Mozambique has been proposed as a host for one of the future Square Kilometre Array stations in Southern Africa. However, Mozambique does not possess a university astronomy department and only recently has there been interest in developing one. South Africa has been funding students at the MSc and PhD level, as well as researchers. Additionally, Mozambicans with Physics degrees have been funded at the MSc level. With the advent of the International Year of Astronomy, there has been a very strong drive, from these students, to establish a successful astronomy department in Mozambique. The launch of the commemorations during the 2008 World Space Week was very successful and Mozambique is to be used to motivate similar African countries who lack funds but are still trying to take part in the International Year of Astronomy. There hare been limited resources and funding, however there is a strong will to carry this momentum into 2009 and, with this, influence the Government to introduce Astronomy into its nationa...

  2. Women's and men's career choices in astronomy and astrophysics

    Ivie, Rachel; White, Susan; Chu, Raymond Y.

    2016-12-01

    [This paper is part of the Focused Collection on Gender in Physics.] The Longitudinal Study of Astronomy Graduate Students (LSAGS) arose from the 2003 Women in Astronomy Conference, where it was noted that a majority of young members of the American Astronomical Society were women. The astronomy community wishes to make every effort to retain young women in astronomy, so they commissioned a longitudinal study to be conducted that would pinpoint the factors that contribute to retention in general, with a focus on differences between women and men. The LSAGS follows a cohort of people who were graduate students in astronomy or astrophysics during 2006-07. The first survey was conducted during 2007-08 and the second during 2012-13. The analysis presented in this paper used a subset of the respondents, all of whom had Ph.D.s in astronomy, astrophysics, or a related field at the time of the second survey. We tested the effects of four major concepts on two measures of attrition from physics and astronomy. These concepts included the imposter syndrome, mentoring and advising during graduate school, the "two-body problem" that occurs when a couple needs to find two jobs in the same geographic area, and the sex of the respondent. While the imposter syndrome and mentoring affected the likelihood of respondents' thinking about leaving the field, they did not directly contribute to actually working in a field that was not physics or astronomy. Relationship with graduate advisors and the two-body problem both had significant effects on working in physics or astronomy, as did completing a postdoc. The sex of the respondent had no direct effect on our measures of attrition, but indirectly affected attrition because women were less likely to report positive relationships with graduate advisors and more likely to report two-body problems. This research identifies specific areas of concern that can be addressed by the scientific community to increase the retention of all people

    For nearly four years, NASA's Kepler space telescope searched for planets like Earth around more than 150,000 stars similar to the Sun. In 2008 with in-kind support from several technology companies, our non-profit organization established the Pale Blue Dot Project, an adopt-a-star program that supports scientific research on the stars observed by the Kepler mission. To help other astronomy educators conduct successful fundraising efforts, I describe how this innovative crowdfunding program successfully engaged the public over the past seven years to help support an international team in an era of economic austerity.

    An overview is presented of current achievements and future possibilities that exist in planetary astronomy. Planetary astronomers employ a wide range of techniques, from straightforward telescopic observation to laboratory analysis of meteorites and cosmic dust. Much of this work focuses on three fundamental questions: how abundant are planets throughout the universe, how did the solar system form, and what can other planets tell us about earth? Several examples show that many recent discoveries reveal the continuing value of earth-orbit and ground-based methods for planetary studies.

  5. Asynchronous, web-based course in astronomy

    Science.gov (United States)

    Spergel, M.

    The course described here is a general educational, non-prerequisite and non- mathematical college course in astronomy offered on the web. It consists of readings from the text plus other periodical sources both online and offline. The course also requires the student to utilize a virtual planetarium to perform exercises in viewing the sky. The students respond to conceptual, multiple-choice questions. This course gives the student a sense of the night sky through the use of computer simulations and night observation. The students learn to understand and express scientific ideas. In addition, since the course is enhanced in computer usage and writing, students also develop these important skills.

  6. 'Land-marks of the universe': John Herschel against the background of positional astronomy.

    Science.gov (United States)

    Case, Stephen

    2015-01-01

    John Herschel (1792-1871) was the leading British natural philosopher of the nineteenth century, widely known and regarded for his work in philosophy, optics and chemistry as well as his important research and popular publications on astronomy. To date, however, there exists no extended treatment of his astronomical career. This paper, part of a larger study exploring Herschel's contributions to astronomy, examines his work in the context of positional astronomy, the dominant form of astronomical practice throughout his lifetime. Herschel, who did not himself practice positional astronomy and who was known for his non-meridional observations of specific stellar objects, was nonetheless a strong advocate for positional astronomy-but for very different reasons than the terrestrial applications to which it was most often put. For Herschel, the star catalogues of positional astronomy were the necessary observational foundation upon which information about the stars as physical objects could be constructed. Positional astronomy practiced in the great national observatories was not about navigation or timekeeping; it was a way to standardize stellar observations and make them useful data for constructing theories of the stars themselves. For Herschel, the seeds of the new astronomy emerged from the practices of the old.

    Gangui, A.; Iglesias, M.; Quinteros, C.

    Models constructed by scientists to explain the world often incorporate their actual individual conceptions about different physical phenomena. Likewise, prospective teachers reach general science courses with preconstructed and consistent models of the universe surrounding them. In this project we present a series of basic questionings that make us reflect on the present situation of the teaching-learning relationship in astronomy within the framework of formal education for elementary school teachers. Our project main aims are: 1) to contribute to finding out the real learning situation of preservice elementary teachers, and 2) from these studies, to try and develop didactic tools that can contribute to improve their formal education in topics of astronomy. In spite of being of chief importance within the science teaching topics, mainly due to its interdisciplinarity and cultural relevance, researches in didactics of astronomy are not well represented in our research institutes.

    The Andean Regional Office of Astronomy for Development (ROAD) is a new effort in South America to serve several goals in astronomical development. Six countries (Bolivia, Colombia, Chile, Ecuador, Perú and Venezuela) will work together, representing a common language block in the Andean region and focusing on develop strategies to strengthen the professional research, education and popularization of astronomy. Our current Working Structure comprises a ROAD Coordinator and Coordinators per Task Force, as well as Organizing Committees, Collaborators and Volunteers.The participating institutions of this new ROAD have been involved in many projects involving each of the current OAD’s Task Forces: research, schools and children and public, exploring educational activities/material to be shared among the Andean countries, standardizing the knowledge and creating inspirational experiences. We expect to generate many efforts in order to bring a more homogeneous activity in each Andean country, taking into account the special role of Chile in global astronomy, due to its great conditions for astronomy and the involvement of many professional observatories, universities and astronomy institutions.Our current (and upcoming) most relevant activities includes: Andean Schools on Astronomy, Andean Graduate Program and Massive Open Online Courses (TF1); Virtual Training Sessions and Teaching material for the visually impaired students; Annual TF2 meeting to gather all the collaborators (TF2); Development for planetariums and Communicating Astronomy with the Public (TF3). The Andean region, in the other hand, will also be involved in at least two important events: the CAP Meeting in May 2016 and the XV LARIM in October 2016 (both in Colombia); and Chile will bid to host the XXXI IAU GA in 2021, with the aim of show the great advances in astronomical development from the Andean region and South America.

  13. Professional Astronomy without a Librarian

    2002-01-01

    Virtually every ``serious'' place where professional astronomy is done has a librarian, even if shared with the physics or math department. Since its creation in 1994 of Departamento de Astronom\\'{i}a (DA) of Universidad de Guanajuato (UG) it was neither provided with a librarian, nor with proper space for its holdings, nor with a budget allowing institutional journal subscriptions. I describe my experience of now five years as ``amateur'' librarian, and present information on other small astronomy institutions in Mexico in a similar situation.

    Practical Astronomy with your Calculator, first published in 1979, has enjoyed immense success. The author's clear and easy to follow routines enable you to solve a variety of practical and recreational problems in astronomy using a scientific calculator. Mathematical complexity is kept firmly in the background, leaving just the elements necessary for swiftly making calculations. The major topics are: time, coordinate systems, the Sun, the planetary system, binary stars, the Moon, and eclipses. In the third edition there are entirely new sections on generalised coordinate transformations, nutr

  18. Evolution of Scholarly Publishing and Library Services in Astronomy Its Impact, Challenges, and Opportunities

    Science.gov (United States)

    Wesley, Hema; Sheshadri, Geetha

    2016-10-01

    Scholarly publishing and its procedures have evolved rapidly, forcefully, and incredibly. Technical advances in the production and promotion of science content have dramatically augmented the visibility and reach, deepened the impact and intensified the thrust of science journal content. These changes range from checking text on perforated tapes to pit stop; from hot metal types to CTP; and from Gutenberg to colour digital printers. Intrinsic and inextricable to this revolutionary aspect of evolution in scholarly publishing is the evolution of library services in astronomy which catapulted library resources from preprints on shelves to customised digital repositories and from communicating observational data through postal telegrams to Tablets. What impact does this unique blend of revolutionary advances have on science and society, what are the consequent challenges, and what are the opportunities that can metamorphose from challenges inherent in the power and potential of the `published word'? The perspectives expressed in this paper stem from learning experiences of the authors at the Indian Academy of Sciences, publishers of ten science journals including the Journal of Astrophysics and Astronomy, and at the Raman Research Institute Library (in which Astronomy is one of the core subjects for research)

  1. Candidates of World Heritage Sites of Astronomy in Japan

    Science.gov (United States)

    Watanabe, Jun-ichi; Nakagiri, Masao

    2015-08-01

    Unfortunately there is no heritage site of astronomy until now in Japan. Here we report several candidates based on the importance from the historical point of view.One is the “Nisshinkan” Astronomical Observatory site of the Edo era. Many observatories were established in the Edo era, including "Asakusa observatory" of a Shogunate Government. However, most of them have been disappeared by the urban development. The only one remained until now is the “Nissshinkan” Astronomical Observatory site of which the basement made of stones is preserved. This was made in 1803 mainly for educational purpose at the “Nisshinkan” which was a local school for the Samurai’s children in Aizu area. Although a wooden building of the school was lost by a war, but this observatory mark exists because large basement of a few meters high remained. This site is now designated as a cultural asset by the local government, and can be recognized even at the present time.Another is the Repsold Meridian Transit which was designated as the Important Cultural Property of Japan in 2011. A Repsold meridian transit instrument is a telescope with a diameter of 13.5 cm and a focal length of 212 cm for meridian transit observations. It was manufactured by A. Repsold & Soehne Co. Ltd. in Hamburg, Germany in 1880, and purchased by the Naval Observatory and imported to Japan in 1881, becoming one of the most important telescopes in the dawning era of modern astronomy in Japan. The telescope escaped being damaged in the Great Kanto Earthquake, and continued to be used as a main telescope for time determination, longitude observation, and astrometry of heavenly bodies till the end of the 1950s. We confirmed that this telescope has retained its original form in 2008, and after restoration and repair, the telescope was widely opened for exhibition to the public. In June, 2011 it was designated as one of the important cultural properties of Japan. The related old instruments which brought modern

    1994-01-01

    X-ray and gamma ray astronomy was made possible by the advent of space flight. Discovery and early observations of celestial x-rays and gamma rays, dating back almost 40 years, were first done with high altitude rockets, followed by Earth-orbiting satellites> once it became possible to carry detectors above the Earth's atmosphere, a new view of the universe in the high-energy part of the electromagnetic spectrum evolved. Many of the detector concepts used for x-ray and gamma ray astronomy were derived from radiation measuring instruments used in atomic physics, nuclear physics, and other fields. However, these instruments, when used in x-ray and gamma ray astronomy, have to meet unique and demanding requirements related to their operation in space and the need to detect and measure extremely weak radiation fluxes from celestial x-ray and gamma ray sources. Their design for x-ray and gamma ray astronomy has, therefore, become a rather specialized and rapidly advancing field in which improved sensitivity, higher energy and spatial resolution, wider spectral coverage, and enhanced imaging capabilities are all sought. This text is intended as an introduction to x-ray and gamma ray astronomy instruments. It provides an overview of detector design and technology and is aimed at scientists, engineers, and technical personnel and managers associated with this field. The discussion is limited to basic principles and design concepts and provides examples of applications in past, present, and future space flight missions.

    2016-06-01

    The International Workshop on Quark Phase Transition in Compact Objects and Multimessenger Astronomy: Neutrino Signals, Supernovae and Gamma-Ray Bursts (October, 7-14, 2015) was dedicated to Quantum ChromoDynamics (QCD) Phase Transitions and observational signals of these transitions related to formation of compact astrophysical objects. The aim of this workshop was to bring together researchers working on the problems of behavior of matter under critical conditions achievable in such astrophysical objects as "strange" or "hybrid" stars and in laboratories at heavy-ion collisions to discuss fundamental issues and recent developments. Topics included both observations (radio, optical and X-ray astronomy, gamma ray bursts, gravitational waves, neutrino detection, heavy-ion collisions, etc.) and theory (supernova simulations, proto-neutron and neutron stars, equation of state of dense matter, neutron star cooling, unstable modes, nucleosynthesis, explosive transitions, quark-gluon plasma).

    2013-12-01

    Athabasca University (AU), Athabasca University Geophysical and Geo-Space Observatories (AUGO / AUGSO), the Rotary Club of Athabasca and Science Outreach Athabasca has designed a three day science workshop entitled Photography and the Night Sky. This pilot workshop, aimed primarily at high-school aged students, serves as an introduction to observational astronomy as seen in the western Canadian night sky using digital astrophotography without the use of a telescope or tracking mount. Participants learn the layout of the night sky by proficiently photographing it using digital single lens reflex camera (DSLR) kits including telephoto and wide-angle lenses, tripod and cable release. The kits are assembled with entry-level consumer-grade camera gear as to be affordable by the participants, if they so desire to purchase their own equipment after the workshop. Basic digital photo editing is covered using free photo editing software (IrfanView). Students are given an overview of observational astronomy using interactive planetarium software (Stellarium) before heading outdoors to shoot the night sky. Photography is conducted at AU's auroral observatories, both of which possess dark open sky that is ideal for night sky viewing. If space weather conditions are favorable, there are opportunities to photograph the aurora borealis, then compare results with imagery generated by the all-sky auroral imagers located at the Geo-Space observatory. The aim of this program is to develop awareness to the science and beauty of the night sky, while promoting photography as a rewarding, lifelong hobby. Moreover, emphasis is placed on western Canada's unique subauroral location that makes aurora watching highly accessible and rewarding in 2013, the maximum of the current solar cycle.

    The H.E.S.S. experiment (High Energy Stereoscopic System) consists of four imaging atmospheric Cherenkov telescopes to study the southern astrophysical sources above 100 GeV. This thesis presents the detector as well as the analysis chain. The calibration methods are described in details and the systematic errors on the image amplitude are derived. Then, an analysis based on a semi-analytical model of the electromagnetic shower development in the atmosphere is presented. Tools to reconstruct the energy spectrum and the morphology of the very high energy {gamma}-ray sources are presented and applied to the Crab Nebula. Systematic errors associated to the spectrum analysis are estimated. All these techniques were applied to study the Galactic Centre emission above 100 GeV. The nature of the source detected in 2003 and 2004 observations is still unknown and its spectrum, variability and morphology are studied. Various candidates are proposed, among them the supermassive black hole Sgr A* located at the dynamical centre of the Milky Way, the supernova remnant Sgr A Est or interactions of accelerated particles with the dense medium of this region. In this thesis, the signal was interpreted in terms of dark matter annihilation (neutralinos or Kaluza-Klein bosons) in a dense halo located at the Galactic Centre. This analysis showed that, in the framework of these models, dark matter annihilation alone can not explain the H.E.S.S. signal. The main component would thus come from astrophysical sources.

    Laboratory astrophysics and complementary theoretical calculations are the foundations of astronomy and astrophysics and will remain so into the foreseeable future. The impact of laboratory astrophysics ranges from the scientific conception stage for ground-based, airborne, and space-based observatories, all the way through to the scientific return of these projects and missions. It is our understanding of the under-lying physical processes and the measurements of critical physical parameters that allows us to address fundamental questions in astronomy and astrophysics. In this regard, laboratory astrophysics is much like detector and instrument development at NASA, NSF, and DOE. These efforts are necessary for the success of astronomical research being funded by the agencies. Without concomitant efforts in all three directions (observational facilities, detector/instrument development, and laboratory astrophysics) the future progress of astronomy and astrophysics is imperiled. In addition, new developments i...

    2000-08-01

    We present selected results from the January 1999 semester pre-course administration of the Astronomy Diagnostic Test (ADT), a research-based, multiple-choice instrument that assesses student knowledge and understanding about selected concepts in astronomy. The ADT is valid for undergraduate non-science majors taking an introductory astronomy course. This paper briefly summarises the development and validation processes, which included pre-course administration to 1557 students in 22 classes attending 17 various post-secondary institutions across the USA in the January 1999 semester. Two interesting results of the ADT's pre-course administration are (1) the average class score of the ADT is about the same (32%) regardless of type of post-secondary institution or class size and (2) there is a significant gender difference, with women scoring an average of 28% and men 38%, with the standard errors both less than 1%. The current version of the ADT (Version 2 dated 21 June 1999) and a comparative by-class database is available to astronomy instructors at the (USA) Association of Astronomy Educators' and the National Institute for Science Education's (NISE) WebPages.

    We describe a collaborative effort to update and unify the various vocabularies currently in use in Astronomy into a single thesaurus that can be further developed and updated through broad community participation. The Unified Astronomy Thesaurus (UAT) will be an open, interoperable and community-supported thesaurus which unifies the existing divergent and isolated Astronomy & Astrophysics thesauri into a single high-quality, freely-available open thesaurus formalizing astronomical concepts and their inter-relationships. The UAT builds upon the existing IAU Thesaurus with major contributions from the Astronomy portions of the thesauri developed by the Institute of Physics Publishing and the American Institute of Physics. While the AAS has assumed formal ownership of the UAT, the work will be available under a Creative Commons License, ensuring its widest use while protecting the intellectual property of the contributors. We envision that development and maintenance will be stewarded by a broad group of parties having a direct stake in it. This includes professional associations (IVOA, IAU), learned societies (AAS, RAS), publishers (IOP, AIP), librarians and other curators working for major astronomy institutes and data archives. While the impetus behind the creation of a single thesaurus has been the wish to support semantic enrichment of the literature, we expect that use of the UAT (along with other vocabularies and ontologies currently being developed) will be much broader and will have a greater impact on discovery of both literatue and data products.

  12. How Create an Astronomy Outreach Program to Bring Astronomy to Thousands of People at Outdoor Concerts Astronomy Festivals, or Tourist Sites

    Lubowich, Donald

    2015-08-01

    I describe how to create an astronomy program for thousands of people at outdoor concerts based on my $308,000 NASA-funded Music and Astronomy Under the Stars (MAUS) program (60 events 2009 - 2013), and the Astronomy Festival on the National Mall (AFNM, 10,000 people/yr).MAUS reached 50,000 music lovers at local parks and at the Central Park Jazz, Newport Folk, Ravinia, or Tanglewood Music Festivals with classical, folk, pop/rock, opera, Caribbean, or county-western concerts assisted by astronomy clubs. Yo-Yo-Ma, the Chicago and Boston Symphony Orchestras, Ravi Coltrane, Esperanza Spalding, Phish, Blood Sweat and Tears, Deep Purple, Tony Orlando, and Wilco performed at these events. AFNM was started in 2010 with co-sponsorship by the White House Office of Science and Technology Policy. MAUS and AFMN combine solar, optical, and radio telescope observations; large posters/banners; hands-on activities, imaging with a cell phone mount; citizen science activities; hand-outs; and teacher info packet. Representatives from scientific institutions participated. Tyco Brahe, Johannes Kepler, and Caroline Herschel made guest appearances.MAUS reached underserved groups and attracted large crowds. Young kids participated in this family learning experience-often the first time they looked through a telescope. While enjoyable and understandable; learned about astronomy; wanted to learn more; and increased their interest in science (ave. rating 3.6/4). MAUS is effective in promoting science education!Lessons learned: plan early; create partnerships with parks, concert organizers, and astronomy clubs; test equipment; have backup equipment; create professional displays; select the best location to obtain a largest number of participants; use social media/www sites to promote the events; use many telescopes for multiple targets; project a live image or video; select equipment that is easy to use, store, set-up, and take down; use hands-on astronomy activities; position the displays

  13. Visual lunar and planetary astronomy

    Abel, Paul G

    2013-01-01

    With the advent of CCDs and webcams, the focus of amateur astronomy has to some extent shifted from science to art. The object of many amateur astronomers is now to produce “stunning images” that, although beautiful, are not intended to have scientific merit. Paul Abel has been addressing this issue by promoting visual astronomy wherever possible – at talks to astronomical societies, in articles for popular science magazines, and on BBC TV’s The Sky at Night.   Visual Lunar and Planetary Astronomy is a comprehensive modern treatment of visual lunar and planetary astronomy, showing that even in the age of space telescopes and interplanetary probes it is still possible to contribute scientifically with no more than a moderately priced commercially made astronomical telescope.   It is believed that imaging and photography is somehow more objective and more accurate than the eye, and this has led to a peculiar “crisis of faith” in the human visual system and its amazing processing power. But by anal...

    One of the major challenges in Egypt is the quality of education. Egypt has made significant progress towards achieving the Education for All and the Millennium Development Goals (MDGs). Many associations and committees as education reform program and education support programs did high efforts in supporting scientific thinking through the scientific clubs. The current state of astronomical education in Egypt has been developed. Astronomy became a part in both science and geography courses of primary, preparatory and secondary stages. Nowadays the Egyptian National Committee for Astronomy, put on its shoulders the responsibility of revising of astronomy parts in the education courses, beside preparation of some training programs for teachers of different stages of educations, in collaboration with ministry of education. General lectures program has been prepared and started in public places , schools and universities. Many TV and Radio programs aiming to spread astronomical culture were presented. In the university stage new astronomy departments are established and astrophysics courses are imbedded in physics courses even in some private universities.

  18. Variable Star Astronomy Education & Public Outreach Initiative

    Science.gov (United States)

    Young, Donna L.

    2008-05-01

    The American Association of Variable Star Observers (AAVSO) published a comprehensive variable star curriculum, "Hands-On Astrophysics, Variable Stars in Science, Math, and Computer Education" in 1997. The curriculum, funded by the National Science Foundation, was developed for a comprehensive audience -- amateur astronomers, classroom educators, science fair projects, astronomy clubs, family learning, and anyone interested in learning about variable stars. Some of the activities from the Hands-On Astrophysics curriculum have been incorporated into the educational materials for the Chandra X-Ray Observatory's Educational and Public Outreach (EPO) Office. On two occasions, in 2000 and 2001, triggered by alerts from amateur astronomers, Chandra observed the outburst of the dwarf nova SS Cygni. The cooperation of amateur variable star astronomers and Chandra X-Ray scientists provided proof that the collaboration of amateur and professional astronomers is a powerful tool to study cosmic phenomena. Once again, the Chandra and AAVSO have teamed up -- this time to promote variable star education. The Hands-On Astrophysics curriculum is being re-designed and updated from the original materials to a web-based format. The new version, re-named Variable Star Astronomy, will provide formal and informal educators, and especially amateur astronomers, educational materials to help promote interest in and knowledge of variable stars.

    CERN Document Server

    Iglesias, Maria; Gangui, Alejandro

    2008-01-01

    Both the basic educational contents for students and study programs for science teachers include several topics in physics and astronomy, from the simplest ones to others as advanced as nuclear fusion to explain stellar evolution and space-time geometry for an approach to modern cosmology. In all these subjects, and most often in the simplest ones, alternative conceptions emerge, as both groups reach science course with preconstructed and consistent models of the universe surrounding them. In this work we present a series of basic questionings that make us reflect on the present situation of the teaching-learning relationship in astronomy within the framework of formal education. We then briefly explain our project aiming at finding the real learning situation of both students and prospective primary-school teachers in astronomical topics and, from the expected results of it, we point towards the need to develop didactic tools that could contribute to improve formal education in astronomy issues.

    We discuss ``Afterschool Universe,'' an astronomy after-school program for middle-schoolers. The program explores basic astronomy concepts through engaging activities and takes participants on a journey through the universe beyond the solar system. By offering astronomy content in out-of-school-time where schedules are less constrained, we can engage students at this critical age in science they find naturally interesting. This is a timely effort for the International Year of Astronomy as it can be used to introduce new audiences to astronomy during a period when we are attempting to raise the profile and level of interest in the universe around us.

    Dick, Wolfgang R.; Hamel, Jürgen

    This issue comprises talks presented 2000 September 18 at the colloquium ``International relations in astronomy'' it is supplemented by additional articles about this topic. The foundation of the international ``Vereinigte Astronomische Gesellschaft'', which took place in 1800 in Bremen, prompted us to investigate the development of astronomy in German-speaking regions, and its international relations during the 19th century. We investigate the activities of famous astronomers like W. Olbers, J.E. Bode, F.X. von Zach, J.H. Schroeter, H.C. Schumacher and K. Schwarzschild, as well as those of their less famous professional colleagues like J.G. Schrader and L. de Ball. The geographical spectrum extends from Bremen and Lilienthal over Kiel, Gotha and Dresden to Copenhagen, Vienna and Chile. Among the topics are: telescope construction, including telescopes made by Herschel, the rediscovery of the minor planet Ceres 1801/02, the Berlin ``Astronomisches Jahrbuch'', the foundation of the ``Astronomische Nachrichten'', the evolution from the ``Vereinigte Astronomische Gesellschaft'' to the present-day ``Astronomische Gesellschaft'', the research at the Kuffner Observatory in Vienna, the professionalization in astronomy, and the attempts of many countries to establish a southern observatory in Chile. A listing of astronomical monuments in Lilienthal and Bremen concludes the book. All papers are written in German with English abstracts.

  4. How to Increase Correct Learning of Astronomy

    Hojaev, Alisher S.

    Astronomy is the most popular and attractive among the sciences. Undoubtedly the importance of exact knowledge of astronomy is becoming more and more important. However the level of teaching of astronomy at schools lyceums colleges and even universities especially in the FSU countries is far to be satisfactorily. Moreover some astronomy related information in the mass media (TV newspapersetc.) has often an incorrect statements. We see the key role of astronomical organizations and each of astronomers in an application of the correct knowledge in the curriculum popularization and control of the astronomical presentations in the mass media. The wide spreading of the Internet recently having place particularly in Uzbekistan gives a new possibilities for increase the learning of astronomy utilize the remote education tools open new frontiers for wide popularization of astronomy. The arrangement of practical excursions public lectures and presentations of the news in astronomy held in UBAI is discussed. Some other idea to improve are given.

    AstroJazz is an innovative public education program in astronomy that blends stunning imagery with live jazz music and a touch of humor to awaken the cosmic curiosity of both adults and children. The program debuted in February 2005 at the Fiske Planetarium on the campus of the University of Colorado, Boulder with an astronomer-chanteuse (the author), a pianist, bassist, drummer, and technical assistant who created dome effects to compliment the PowerPoint slides associated with each song. This AstroJazz quartet played ten songs, five original tunes (Look Up!, Are We Alone? Andromeda Affaire, StarMan Blues, Star Kissed)), and five standard tunes with lyrical twists toward astronomy & astrobiology (e.g. Stormy Weather - Solar Style and Stardust a la SETI.) The hour-long program also includes educational interludes where the astronomy chanteuse interacts with the audience, providing insights and perspective into the wonders of our universe. The performance program that is handed to all audience members contains additional "gee-whiz" facts and provides leads to websites like Astronomy Picture of the Day and spaceweather.com that provide ongoing points of contact for public interest in astronomy. AstroJazz was very well received in its debut performance and now has several new opportunities to perform. Anecdotal evidence suggests that the AstroJazz program is engaging and educational for a very broad audience, including families with young children, world-class astronomers, and spouses of musicians who had never before been exposed to astronomy. This paper will describe the origins and intended evolution of AstroJazz, and offer a mini-sample of the music and slides used in the program. It will also discuss strategies for how the impact on audiences might be assessed.

    The ionospheric behavior over Belgium during the partial solar eclipse of 20 March 2015 is analyzed based on high-resolution solar radio flux, vertical incidence sounding, and GPS TEC measurements. First results of ionosonde-based ionospheric plasma drift and tilt observations are presented and analyzed, including some traveling ionospheric disturbances caused by the eclipse. Also, collocated ionosonde and GPS measurements are used to reconstruct the time evolution of the vertical electron density distribution using the Royal Meteorological Institute (RMI) ionospheric specification system, called Local Ionospheric Electron Density profile Reconstruction (LIEDR).

  10. Astronomy, Visual Literacy, and Liberal Arts Education

    Crider, Anthony

    2016-01-01

    With the exponentially growing amount of visual content that twenty-first century students will face throughout their lives, teaching them to respond to it with visual and information literacy skills should be a clear priority for liberal arts education. While visual literacy is more commonly covered within humanities curricula, I will argue that because astronomy is inherently a visual science, it is a fertile academic discipline for the teaching and learning of visual literacy. Astronomers, like many scientists, rely on three basic types of visuals to convey information: images, qualitative diagrams, and quantitative plots. In this talk, I will highlight classroom methods that can be used to teach students to "read" and "write" these three separate visuals. Examples of "reading" exercises include questioning the authorship and veracity of images, confronting the distorted scales of many diagrams published in astronomy textbooks, and extracting quantitative information from published plots. Examples of "writing" exercises include capturing astronomical images with smartphones, re-sketching textbook diagrams on whiteboards, and plotting data with Google Motion Charts or iPython notebooks. Students can be further pushed to synthesize these skills with end-of-semester slide presentations that incorporate relevant images, diagrams, and plots rather than relying solely on bulleted lists.

    2009-12-01

    The opportunity offered by the International Year of Astronomy (IYA) 2009 to increase the exposure of the public and students to NASA discoveries in astronomy resulted in several innovative programs which have reached audiences far and wide. Some examples of the impact of these programs and building on the success of these programs beyond 2009 will be discussed in this talk. The spectacular success of the traveling exhibit of NASA images to public libraries around the country prompted NASA to extend it to include more libraries. As a part of the IYA Cornerstone project From Earth To The Universe, NASA images were displayed at non-traditional sites such as airports, parks, and music festivals, exposing them to an audience which would otherwise have been unaware of them. The NASA IYA Student Ambassadors engaged undergraduate and graduate students throughout the U.S. in outreach programs they created to spread NASA astronomy to their local communities. NASA’s Afterschool Universe provided IYA training to community-based organizations, while pre-launch teacher workshops associated with the Kepler and WISE missions were designed to engage educators in the science of these missions. IYA activities have been associated with several missions launched this year. These include the Hubble Servicing Mission 4, Kepler, Herschel/Planck, LCROSS. NASA’sIYA website and Go Observe! feature remain popular. The associated IYA Discovery Guides and Observing with NASA MicroObservatory activities have guided the public and students to perform their own observations of the night sky and to interpret them. NASA intends to work with its Science Education and Public Outreach Forums (SEPOF) to develop a strategy to take forward the best of its IYA2009 plans forward so as to build on the momentum generated by IYA2009 and continue to keep the public and students engaged in the scientific exploration of the universe.

  18. The stars, the moon, and the shadowed earth: Viennese astronomy in the fifteenth century

    Science.gov (United States)

    Byrne, James Steven

    This dissertation is a study of astronomy at the University of Vienna from the beginning of the fifteenth century through the career of Johannes Regiomontanus (d. 1476), the university's most celebrated astronomer. Regiomontanus and his mentor Georg Peurbach (d. 1461) established a framework for the practice of astronomy, including the linkage of cosmology to astronomy, attempts to correct the errors and ambiguities of the medieval astronomical tradition, a renewed interest in Ptolemy's Almagest , and a program of observations intended as a basis for the reform of planetary tables and models, that remained in place for the more celebrated astronomical achievements of the following century. This study traces the roots of this framework to astronomical teaching at the University of Vienna in the first half of the fifteenth century, as well as its expansion by Regiomontanus as he moved from Vienna to Italy, Hungary, and Germany. Chapter One provides background for the reader unfamiliar with medieval, Ptolemaic astronomy, and also argues that the shift described in the next chapter was, in part, motivated by astrological concerns. Chapter Two demonstrates that, by the middle of the fifteenth century, Viennese astronomy had come to incorporate a significant element of Aristotelian cosmology. Chapter Three examines fourteenth- and fifteenth-century responses to the Theorica planetarum , the most common astronomical teaching text at medieval universities, arguing that university astronomers were capable of identifying and addressing problems with the Theorica in a sophisticated manner. Chapter Four argues that the seemingly contradictory aspects of Regiomontanus's astronomical career can be understood as all contributing to a program of reform that encompassed both the correction of astronomical tables on the basis of new and comprehensive observations as well as the construction of homocentric planetary models to replace the venerable Ptolemaic system. Chapter Five shows

    Active Galactic Videos is an astronomy-focused YouTube channel run by a team at the University of Arizona. The channel has two main purposes: to produce educational content for public audiences, and to learn about astronomy and to open a window into the world of professional astronomy by showcasing the work done at Steward Observatory and in Southern Arizona. Our team consists of faculty, staff, and students from a variety of backgrounds including: astronomy, education, film, music, english, and writing. In addition to providing educational content for public audiences, this project provides opportunities for undergraduate students to learn about astronomy content, educational practice, and science communication while developing the practical skills needed to write, film, score, direct, and edit videos that effectively engage and teach viewers about topics in astronomy. The team has produced various styles of video: presentational, interviews, musical/poetic, and documentaries. In addition to YouTube, the Active Galactic Videos team maintains a social media presence on Facebook, Twitter, and Instagram. These help to widely distribute the content as well as to publicize the main Youtube channel. In addition to providing an overview of our educational work, this poster will present a year's worth of online analytics that we are using to better understand our audience, to examine what videos have been popular and successful and how people are accessing our content. We will present our experience in order to help others learn about improving astronomy education online, and astronomy communication and outreach in general.

    2014-07-01

    Despite being part of the official documents astronomy is rarely taught adequately in basic education. Digital technologies are commonly used by youth, but neglected by the majority of teachers. In this sense, a survey with the aim of pointing out the potential use of digital technologies in teaching astronomy was developed. An advanced course in astronomy was offered for participants with the goal to make them understand astronomical phenomena. The following steps were to be taken: i) analysis of the pedagogical projects (PPC) of the licenciates at the Federal Institution of the North of Minas Gerais (IFNMG); ii) analysis of students' preconceptions about astronomy and digital technologies; iii) preparation of the course; iv) application of the education proposal. The test consisted of thirty-two students of physics, mathematics and biology and was conducted with the qualitative and quantitative methodology, combined with a content analysis. The results indicated that in the IFNMG only the licenciate-course in physics includes astronomy content diluted in various subjects of the curriculum; the rates of students' prior knowledge in relation to astronomy was low; an evidence of meaningfull earning of the concepts related to astronomy, and of viability of resource use involving digital technologies in the Teaching of astronomy.

    Background Although several reports concerning the association of iodine excess and thyroid disease have appeared, no systematic review of the association between iodine excess intake and thyroid diseases, especially hyperthyroidism and hypothyroidism, has yet been reported. Method We conducted a systematic search of Ovid MEDLINE, PubMed, Cochrane Central Register of Controlled Trials databases, Ichushi-Web and CiNii database for intervention trials and observational studies. Search terms were constructed from related words for excess AND iodine intake or excretion AND thyroid hormones or diseases AND study designs. After considering the qualitative heterogeneity among studies, a meta-analysis was conducted and odds ratios and 95% confidence intervals (CI) were estimated in random-effects models. A protocol was registered with PROSPERO (No. CRD42015028081). Results 50 articles were included, including three intervention trials, six case-control studies, six follow-up studies and 35 cross-sectional studies. Three cross-sectional studies in adults included in meta-analysis. Odds ratio of overt and subclinical hypothyroidism between excess and adequate populations were 2.78 (CI:1.47 to 5.27) and 2.03 (CI:1.58 to 2.62) in adults, respectively. Source of excess iodine status was mainly iodized salt or water in included studies. Conclusion Although universal salt iodization has improved goiter rates, chronic exposure to excess iodine from water or poorly monitored salt are risk factors for hypothyroidism in free-living populations. Monitoring of both iodine concentration in salt as well as the iodine concentration in local drinking water are essential to preventing thyroid diseases. Hypothyroidism should be also carefully monitored in areas with excess iodine. Because of the low quality and limited number of included studies, further evidence and review are required.

    2003 was the fifth and final year of the NSF-funded ``Towards Other Planetary Systems'' (TOPS) secondary school teacher training program conducted by the Institute for Astronomy in Hawai'i. While previous years concentrated on basic astronomy skills, cultural astronomy and astrobiology, TOPS 2003 focused on training master teachers and prior TOPS participants in the requisite skills to mentor student projects using the Faulkes Telescope-North (FTN), a 2-meter telescope under construction at the Haleakala High Altitude Observatory. The FTN and a twin in Australia will be the world's largest telescopes dedicated solely to education. This poster presentation describes the teacher's experiences with several prototype astrobiology projects suitable for a 2-meter-class telescope, including monitoring variable stars in star-forming regions, detecting extrasolar planet transits, and observing objects in the Kuiper Belt. Plans for partnering teachers with amateur astronomers proficient in observational techniques are also discussed; the American Association of Variable Star Observers (AAVSO) is a likely reservoir of such individuals. The recent selection of a University of Hawai'i group led by the TOPS Director as a NASA Astrobiology Institute Lead Team will provide a framework for development of teacher-student-amateur astronomer teams advised by professional astronomers and conducting astrobiology research. This work was supported by a grant from the National Science Foundation, ESI-9731083, and through University of Maryland and University of Hawaii subcontract Z667702, which was awarded under prime contract NASW-00004 from NASA.

    The SIDECAR ASIC is a fully integrated system-on-a-chip focal plane array controller that offers low power and low noise, small size and low weight. It has been widely used to operate different image sensors for ground-based and flightbased astronomy applications. A key mechanism to operating analog detectors is the SIDECAR ASIC's high level of programmability. This paper gives an overview of the SIDECAR ASIC architecture, including its optimized microcontroller featuring a customized instruction set. It describes the firmware components, including timing generation, biasing, commanding, housekeeping and synchronization of multiple detectors. The firmware development tools including compiler and supporting development environment and hardware setup are presented. The firmware capability for ground-based HxRG applications and for flight-based applications like the James Webb Space Telescope (JWST), the repair of the Advanced Camera for Surveys (ACS), and others are also discussed.

    In the summer of 2000, two teachers working on a Masters of Science Teaching program at New Mexico Institute of Mining and Technology, spent eight weeks as interns at the Array Operations Center for the National Radio Astronomy Observatory (NRAO) in Socorro, New Mexico, under the auspices of the National Science Foundation's (NSF) Research Experience for Teachers (RET) program. The resulting projects will directly benefit students in the indvidual classrooms, as well as provide an easy-to-access resource for other educators. One of the products is a Radio Astronomy Curriculum for upper middle school classes. Radio astronomy images, based on scientific research results using NRAO's Very Large Array, are featured on trading cards which include an explanation, a ``web challenge'', and in some cases, a comparison of radio and optical images. Each trading card has corresponding lesson plans with background information about the images and astronomy concepts needed to do the lessons. Comparison of optical and radio astronomy is used as much as possible to explain the information from research using visible and radio wavelengths. New Mexico's Content Standards and Benchmarks (developed using national standards) for science education was used as a guide for the activities. The three strands of science listed in the standards, Unifying Concepts and Processes, Science as Inquiry, and Science Content are addressed in the lessons. Higher level thinking and problem solving skills are featured throughout the curriculum. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc. The NSF's RET program is gratefully acknowledged.

    The National Science Foundation's GK-12 program encourages graduate students in science to be active in public education at the middle school and high school levels. As a GK-12 fellow at the University of Colorado-Boulder (CU), I worked with a local 8th-grade science teacher and his students during the 2003-2004 school year. In the Boulder Valley School District, 8th-grade science covers Earth history, meteorology, astronomy, and oceanography. There are many special challenges for this school district and 8th-grade education in Colorado, including a large number of English as a second language (ESL) students and the administration of standardized tests during March, before students have completed much of the relevant material. As a GK-12 Fellow, my responsibilities included work with the Earth history Full Option Science System (FOSS) kit, guest lecturing, aid in hands-on exercises, and the creation of new activities and assignments. Astronomy activities accomplished through this program include sunspot viewing and a field trip to the Colorado Scale Model Solar System on the CU campus. The GK-12 program at CU will continue for at least two more years, possibly placing future GK-12 fellows who are astronomy grad students into classes that are astronomy- or physics-specific.

    A fundamental aspect of our jobs as scientists is communicating our work to others. In this, the field of astronomy holds the double-edged sword of ubiquitous fascination: the topic has been of interest to nearly the entire global population at some point in their lives, yet the learning curve is steep within any subfield and rife with difficult-to-synthesize details. Compounding this issue is the ever-expanding array of methods to reach people in today's Communications Era. Each communication medium has its own strengths and weaknesses, is appropriate in different situations, and requires its own specific skillset in order to maximize its functionality. Despite this, little attention is given to training astronomers in effective communication techniques, often relying on newcomers to simply pick up the ability by mimicking others and assuming that a firm grasp on the subject matter will make up for deficiencies in communication theory. This can restrict astronomers to a narrow set of communication methods, harming both the communicators and the audience who may struggle to access the information through those media.Whether writing a research paper to academic peers or giving an astronomy talk to a pubic audience, successfully communicating a scientific message requires more than just an expert grasp on the topic. A communicator must understand the makeup and prior knowledge of the desired audience, be able to break down the salient points of the topic into pieces that audience can digest, select and maximize upon a medium to deliver the message, and frame the message in a way that hooks the audience and compels further interest. In this work we synthesize the requirements of effective astronomy communication into a few key questions that every communicator needs to answer. We then discuss some of the most common media currently used to communicate astronomy, give both effective and poor examples of utilizing these media to communicate astronomy, and provide key

    Background: Partial-thickness tear of the rotator cuff is a common cause of shoulder pain. Magnetic resonance (MR) arthrography has been described as a useful measure to diagnose rotator cuff abnormalities. Purpose: To determine the reliability and accuracy of MR arthrography with abduction and external rotation (ABER) view for the diagnosis of partial-thickness tears of the rotator cuff. Material and Methods: Among patients who underwent MR arthrographies, 22 patients (12 men, 10 women; mean age 45 years) who had either partial-thickness tear or normal tendon on arthroscopy were included. MR images were independently scored by two observers for partial-thickness tears of the rotator cuff. Interobserver and intraobserver agreements for detection of partial-thickness tears of the rotator cuff were calculated by using kappa coefficients. The differences in areas under the receiver operating characteristic (ROC) curves were assessed with a univariate Z-score test. Differences in sensitivity and specificity for interpretations based on different imaging series were tested for significance using the McNemar statistic. Results: Sensitivity, specificity, and accuracy of each reader on MR imaging without ABER view were 83%, 90%, and 86%, and 83%, 80%, and 82%, respectively, whereas on overall interpretation including ABER view, the sensitivity, specificity, and accuracy of each reader were 92%, 70%, and 82%, and 92%, 80%, and 86%, respectively. Including ABER view, interobserver agreement for partial-thickness tear increased from kappa=0.55 to kappa=0.68. Likewise, intraobserver agreements increased from kappa=0.79 and 0.53 to kappa=0.81 and 0.70 for each reader, respectively. The areas under the ROC curves for each reader were 0.96 and 0.90, which were not significantly different. Conclusion: Including ABER view in routine sequences of MR arthrography increases the sensitivity, and inter- and intraobserver agreements for detecting partial-thickness tear of rotator cuff

    Dearborn, David S. P.; Bauer, Brian S.

    Half a millennium ago in the central Andes of Peru, the movements of the sun, moon, and stars were watched and interpreted by the Inca. The astronomical observations made in and near the former capital, Cuzco, formed the nuclei of the most important public rituals of the empire. As the regulator of time, the ruling Inca scheduled the rituals that bound this society together. In this article, we review the major astronomical observations that were made by the Inca and discuss their importance in defining the ritual calendar.

    This article presents an experience report of a workshop held at the State School Professor Plínio Ribeiro, who aimed to spread the use of interactive materials for teaching Astronomy and its relationship with Mathematics during the Forum Biotemas. Despite being part of the official documents, be present in the curricular proposals from several Brazilian states, and has contributed to the human and technological development, Astronomy is rarely taught adequately in basic education, with unsatisfactory results presented by students and teachers. In this sense was held a workshop planned for elementary education students called 'Astronomy and Mathematics: Learn to Observe the Sky With Other Eyes' involving several resources. The methodology consisted of awareness of those involved, presentation videos, using Stellarium software, application of Mathematics in Astronomy and discussions. Among the main results, can highlight students' interest in scientific matters, because when the study of the sciences takes place without interaction with natural and technological phenomena, a huge gap in the education of students occurs. In this sense, the use of different resources, as templates, observations, real and virtual experiments, animations, simulations, video lessons, can arouse the interest of students by conceptual content, differently from what happens when the study takes place using only conventional resources, with books and handouts.

  12. Pre-Inca Astronomy in Peru

    Science.gov (United States)

    McKim Malville, J.

    Huacas (shrines) and ushnus (ceremonial platforms) are ever-present elements of millennia-old Andean cosmology extending backward to 3100 BCE. Major themes of Pan-Andean cosmology include sacred mountains, the power of water, the solstice sun, as well as shamanic-like movement across the three worlds of the cosmos. Common features of many pre-Inca sites are monumental platforms and sunken circular plazas, and stairways with axes established by bi-lateral symmetries oriented along solstice lines. This style of ritual architecture first appeared in Chupacigarro/Caral, other sites in the Norte Chico area, and Sechin Bajo in the Casma Valley. Ceremonial plazas provided opportunities for public viewing of ritual ceremonies on the tops of platforms, which may have been understood as sacred mountains. Mounds and temples of the Casma Valley, such as Sechin Alto, Sechin Bajo, and Chankillo, developed an explicit astronomy associated with June and December solstices. The ritualistic use of water, which is typically associated with visual astronomy at Inca sites, appeared at Chavin de Huantar and later in Tiwanaku.

  13. Astronomy in Brazilian music and poetry

    2011-06-01

    The rôle of astronomy in the Brazilian cultural diversity -though little known world- has been enormous. Thus, the different forms of popular music and erudite, find musical compositions and lyrics inspired by the stars, the eclipses in rare phenomena such as the transit of Venus in front of the sun in 1882, the appearance of Halley's Comet in 1910, in the Big Bang theory. Even in the carnival parades of the blocks at the beginning of the century astronomy was present. More recently, the parade of 1997, the samba school Unidos do Viradouro, under the direction of Joãozinho Trinta, offered a new picture of the first moments of the creation of the universe to join in the white and dark in the components of their school, the idea of matter and anti-matter that reigned in the early moments of the creation of the universe in an explosion of joy. Examples in classical music include Dawn of Carlos Gomes and Carta Celeste by Almeida Prado. Unlike The Planets by Gustav Holst -who between 1914 and 1916 composed a symphonical tribute to the solar system based on astrology- Almeida Prado composed a symphony that is not limited to the world of planets, penetrating the deep cosmos of galaxies. Using various resources of the technique for the piano on the clusters and static movements, violent conflicts between the records of super acute and serious instrument, harpejos cross, etc . . .

  14. Star-Paths, Stones and Horizon Astronomy

    Science.gov (United States)

    Brady, Bernadette

    2015-05-01

    Archaeoastronomers tend to approach ancient monuments focusing on the landscape and the horizon calendar events of sun and moon and, due to problems with precession, generally ignore the movement of the stars. However, locating the position of solar calendar points on the horizon can have other uses apart from calendar and/or cosmological purposes. This paper firstly suggests that the stars do not need to be ignored. By considering the evidence of the Phaenomena, a sky poem by Aratus of Soli, a third century BC Greek poet, and his use of second millennium BC star lore fragments, this paper argues that the stars were a part of the knowledge of horizon astronomy. Aratus' poem implied that the horizon astronomy of the late Neolithic and Bronze Age periods included knowledge of star-paths or 'linear constellations' that were defined by particular horizon calendar events and other azimuths. Knowledge of such star-paths would have enabled navigation and orientation, and by using permanent markers, constructed or natural, to define these paths, they were immune to precession as the stones could redefine a star-path for a future generation. Finally the paper presents other possible intentions behind the diverse orientation of passage tombs and some megalithic sites.

    The purpose of this study is to examine the sequence of events that led to the establishment of the NRAO, the construction and development of instrumentation and the contributions and discovery events and to relate the significance of these events to the evolution of the sciences of radio astronomy and cosmology. After an overview of the resources, a brief discussion of the early days of the science is given to set the stage for an examination of events that led to the establishment of the NRAO. The developmental and construction phases of the major instruments including the 85-foot Tatel telescope, the 300-foot telescope, the 140-foot telescope, and the Green Bank lnterferometer are examined. The technical evolution of these instruments is traced and their relevance to scientific programs and discovery events is discussed. The history is told in narrative format that is interspersed with technical and scientific explanations. Through the use of original data technical and scientific information of historical concern is provided to elucidate major developments and events. An interpretive discussion of selected programs, events and technological developments that epitomize the contributions of the NRAO to the science of radio astronomy is provided. Scientific programs conducted with the NRAO instruments that were significant to galactic and extragalactic astronomy are presented. NRAO research programs presented include continuum and source surveys, mapping, a high precision verification of general relativity, and SETI programs. Cosmic phenomena investigated in these programs include galactic and extragalactic HI and HII, emission nebula, supernova remnants, cosmic masers, giant molecular clouds, radio stars, normal and radio galaxies, and quasars. Modern NRAO instruments including the VLA and VLBA and their scientific programs are presented in the final chapter as well as plans for future NRAO instruments such as the GBT.

    As a part of a larger project to study introductory astronomy students’ worldviews and beliefs about the role of science in society, we examined students’ responses to a subset of questions designed to probe students’ worldviews and how they change after taking a general education, introductory astronomy course (Astro 101). Specifically, we looked at about 400 students’ choices for the top ten scientific discoveries in the past 150 years. We collected students’ rankings twice: Once at the start of their Astro 101 class and once at the end. We created a rubric that we used to categorize the responses and we established the inter-rater reliability of the rubric. Our results show that students preferentially answered with topics related to technology and health and medicine. The data also show that there was an increase, pre- to post-instruction, in the number of responses in the technology and health and medicine categories. We also saw a decrease in the number of responses in the science category. These results imply that an aspect of the course specifically implemented to broaden student’s views on science in relation to society was successful. This material is based upon work supported by the National Science Foundation under Grant No. AST-0847170, for the California-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE) program.

    2015-01-01

    Our best efforts in the United States to dramatically improve teaching and learning in astronomy courses has been less than satisfactory despite Herculean efforts. A possible solution is to expand our view beyond our own culture's borders and presumptions in order to bring our shortcomings in discipline-based astronomy education research to light. Before we can begin the process of international comparisons of student conceptual understanding, we need to better understand how different citizens of different countries position astronomy culturally. Under the banner of the International STudy on Astronomy Reasoning Project, iSTAR, we are now carefully observing how foreign experts in teaching astronomy and the science of astronomy translate the Test Of Astronomy STandards - TOAST multiple-choice assessment instrument to look for subtle clues revealed during the translation process. The TOAST is the widely used standard to evaluate students' gains in the United States' Astronomy classrooms. We hope that the process of translation itself will help us comprehend how other cultures think differently about astronomical concepts and eventually we are looking to obtain useful data of how other cultures develop their society's understanding of particular astronomy aspects where we may fall short. Several of the iSTAR Project's bilingual speakers are documenting their thoughts and insights as they translate the TOAST. The end-goal is to collect a comprehensible, well-defined, and logical translation in various languages that are culturally sensitive and linguistically accurate. This project is sponsored and managed by the CAPER Center for Astronomy & Physics Education Research at CAPERTeam.com in collaboration with members of the International Astronomical Union-Commission 46.

    The traditional cultures of Aboriginal Australians include a significant astronomical component, perpetuated through oral tradition, ceremony, and art. This astronomical component includes a deep understanding of the motion of objects in the sky, and this knowledge was used for practical purposes, such as constructing calendars. There is also evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, paid careful attention to unexpected phenomena such as eclipses and meteorite impacts, and could determine the cardinal points to an accuracy of a few degrees.

Most importantly, I will highlight some areas ripe for collaboration between Python and Julia developers in astronomy.

  5. If ionospheric and geomagnetic disturbances observed before strong earthquakes may result from simultaneous impact of space weather on all geospheres including solid earth

    Khachikyan, Galina

    2016-07-01

    It is revealed in previous decades that ionospheric disturbances precede strong earthquakes, thus, the ionospheric precursors of strong earthquakes are now under developing [Pulinets and Boyarchuk, 2004]. Simultaneously, it is revealed that strong earthquakes may be preceded by geomagnetic disturbances as well, as a result, the geomagnetic variations, for example, in the ULF band, are considered now as precursory signals [Fraser-Smith, 1990, doi/10.1029/GL017i009p01465]. At the same time, there is currently no reliable theory nor for ionospheric or to magnetic precursors of earthquakes. Moreover, several researches have reexamined some of above results and concluded that observed magnetic disturbances before strong earthquakes could be generated by other sources, such as global magnetic activity [e.g. Campbell, 2009, doi/10.1029/2008JA013932], and that ionospheric anomalies can also be an effect of the increase of the global magnetic activity [e. g. Masci and Thomas, 2015, doi:10.1002/2015RS005734]. Taking into account such conclusions, one may suggest that the observed ionospheric and geomagnetic disturbances before strong earthquakes might be due to simultaneous influence of a space weather on the complicated surrounding system including the solid earth. This report presents some statistical results to prove such suggestion. In particular, it is shown [Khachikyan et al., 2012, doi:10.4236/ijg.2012.35109] that maximal possible earthquake magnitude (seismic potential) can be determined, in first approximation, on the base of geomagnetic Z-component measured in the Geocentric Solar Magnetosphere (GSM) coordinate system, in which the space weather impact on the earth's environment, due to reconnection of the solar wind magnetic field with the earth's magnetic field, is more ordered.

  6. A New Approach to Interference Excision in Radio Astronomy: Real-Time Adaptive Cancellation

    Science.gov (United States)

    Barnbaum, Cecilia; Bradley, Richard F.

    1998-11-01

    Every year, an increasing amount of radio-frequency (RF) spectrum in the VHF, UHF, and microwave bands is being utilized to support new commercial and military ventures, and all have the potential to interfere with radio astronomy observations. Such services already cause problems for radio astronomy even in very remote observing sites, and the potential for this form of light pollution to grow is alarming. Preventive measures to eliminate interference through FCC legislation and ITU agreements can be effective; however, many times this approach is inadequate and interference excision at the receiver is necessary. Conventional techniques such as RF filters, RF shielding, and postprocessing of data have been only somewhat successful, but none has been sufficient. Adaptive interference cancellation is a real-time approach to interference excision that has not been used before in radio astronomy. We describe here, for the first time, adaptive interference cancellation in the context of radio astronomy instrumentation, and we present initial results for our prototype receiver. In the 1960s, analog adaptive interference cancelers were developed that obtain a high degree of cancellation in problems of radio communications and radar. However, analog systems lack the dynamic range, noised performance, and versatility required by radio astronomy. The concept of digital adaptive interference cancellation was introduced in the mid-1960s as a way to reduce unwanted noise in low-frequency (audio) systems. Examples of such systems include the canceling of maternal ECG in fetal electrocardiography and the reduction of engine noise in the passenger compartments of automobiles. These audio-frequency applications require bandwidths of only a few tens of kilohertz. Only recently has high-speed digital filter technology made high dynamic range adaptive canceling possible in a bandwidth as large as a few megahertz, finally opening the door to application in radio astronomy. We have

    The IDEAS to Improve Instructional Competencies in Astronomy and Space Science project is intended to develop and/or enhance teacher competencies in astronomy and space sciences of teacher participants (Grades 5-12) in Kentucky. The project is being implemented through a two-week summer workshop, a series of five follow-up meetings, and an academic year research project. The resources of Kentucky's only Radio Astronomy Observatory- the Morehead Radio Telescope (MRT), Goldstone Apple Valley Radio Telescope (GAVRT) (via remote observing using the Internet), and the Kentucky Department of Education regional service centers are combined to provide a unique educational experience. The project is designed to improve science teacher's instructional methodologies by providing pedagogical assistance, content training, involving the teachers and their students in research in radio astronomy, providing access to the facilities of the Morehead Astrophysical Observatory, and by working closely with a NASA-JOVE research astronomer. Participating teachers will ultimately produce curriculum units and research projects, the results of which will be published on the WWW. A major goal of this project is to share with teachers and ultimately students the excitement and importance of scientific research. The project represents a partnership of five agencies, each matching the commitment both financially and/or personnel. This project is funded by the NASA IDEAS initiative administered by the Space Telescope Science Institute and the National Air and Space Administration (NASA).

    We have surveyed a sample of massive star-forming regions located over a range of distances from the Galactic center for methyl formate, HCOOCH{sub 3}, and its isotopologues H{sup 13}COOCH{sub 3} and HCOO{sup 13}CH{sub 3}. The observations were carried out with the APEX telescope in the frequency range 283.4-287.4 GHz. Based on the APEX observations, we report tentative detections of the {sup 13}C-methyl formate isotopologue HCOO{sup 13}CH{sub 3} toward the following four massive star-forming regions: Sgr B2(N-LMH), NGC 6334 IRS 1, W51 e2, and G19.61-0.23. In addition, we have used the 1 mm ALMA science verification observations of Orion-KL and confirm the detection of the {sup 13}C-methyl formate species in Orion-KL and image its spatial distribution. Our analysis shows that the {sup 12}C/{sup 13}C isotope ratio in methyl formate toward the Orion-KL Compact Ridge and Hot Core-SW components (68.4 ± 10.1 and 71.4 ± 7.8, respectively) are, for both the {sup 13}C-methyl formate isotopologues, commensurate with the average {sup 12}C/{sup 13}C ratio of CO derived toward Orion-KL. Likewise, regarding the other sources, our results are consistent with the {sup 12}C/{sup 13}C in CO. We also report the spectroscopic characterization, which includes a complete partition function, of the complex H{sup 13}COOCH{sub 3} and HCOO{sup 13}CH{sub 3} species. New spectroscopic data for both isotopomers H{sup 13}COOCH{sub 3} and HCOO{sup 13}CH{sub 3}, presented in this study, have made it possible to measure this fundamentally important isotope ratio in a large organic molecule for the first time.

    2015-01-01

    Introduction Venous thromboembolism (VTE) with its two manifestations deep vein thrombosis (DVT) and pulmonary embolism (PE) is a major public health problem. The VTEval Project aims to investigate numerous research questions on diagnosis, clinical management, treatment and prognosis of VTE, which have remained uncertain to date. Methods and analysis The VTEval Project consists of three observational, prospective cohort studies on VTE comprising cohorts of individuals with a clinical suspicion of acute PE (with or without DVT), with a clinical suspicion of acute DVT (without symptomatic PE) and with an incidental diagnosis of VTE (PE or DVT). The VTEval Project expects to enrol a total of approximately 2000 individuals with subsequent active and passive follow-up investigations over a time period of 5 years per participant. Time points for active follow-up investigations are at months 3, 6, 12, 24 and 36 after diagnosis (depending on the disease cohort); passive follow-up investigations via registry offices and the cancer registry are performed 48 and 60 months after diagnosis for all participants. Primary short-term outcome is defined by overall mortality (PE-related death and all other causes of death), primary long-term outcome by symptomatic VTE (PE-related death, recurrence of non-fatal PE or DVT). The VTEval Project includes three ‘all-comer’ studies and involves the standardised acquisition of high-quality data, covering the systematic assessment of VTE including symptoms, risk profile, psychosocial, environmental and lifestyle factors as well as clinical and subclinical disease, and it builds up a large state-of-the-art biorepository containing various materials from serial blood samplings. Ethics and dissemination The VTEval Project has been approved by the local data safety commissioner and the responsible ethics committee (reference no. 837.320.12 (8421-F)). Trial results will be published in peer-reviewed journals and presented at national and

    2013-01-01

    We survey the present landscape in submillimetre astronomy for Canada and describe a plan for continued engagement in observational facilities to ~2020. Building on Canada's decadal Long Range Plan process, we emphasize that continued involvement in a large, single-dish facility is crucial given Canada's substantial investment in ALMA and numerous PI-led submillimetre experiments. In particular, we recommend: i) an extension of Canadian participation in the JCMT until at least the unique JCMT Legacy Survey program is able to realize the full scientific potential provided by the world-leading SCUBA-2 instrument; and ii) involvement of the entire Canadian community in CCAT, with a large enough share in the partnership for Canadian astronomers to participate at all levels of the facility. We further recommend continued participation in ALMA development, involvement in many focused PI-led submillimetre experiments, and partnership in SPICA.

    2000-01-01

    Radio-astronomical observations are increasingly corrupted by RF interference, and online detection and filtering algorithms are becoming essential. To facilitate the introduction of such techniques into radio astronomy, we formulate the astronomical problem in an array signal processing language, and give an introduction to some elementary algorithms from that field. We consider two topics in detail: interference detection by rank estimation of short-term covariance matrices, and spatial filtering by subspace estimation and projection. We discuss experimental data collected at the Westerbork radio telescope, and illustrate the effectiveness of the space-time detection and blanking process on the recovery of a 3C48 absorption line in the presence of GSM mobile telephony interference.

  17. Next Generation Radio Astronomy Receiver Systems

    CERN Document Server

    Morgan, Matthew A

    2009-01-01

    Radio astronomy observations in the coming decade will require new levels of sensitivity while mapping large regions of space with much greater efficiency than is achieved with current telescopes. This requires new instrumentation with the greatest achievable sensitivity, dynamic range, and field of view. Receiver noise is quickly approaching fundamental limits at most radio wavelengths, so significant gains in sensitivity can only be made by increasing collecting area. Jointly, these requirements suggest using large arrays of smaller antennas, or many moderate-size antennas equipped with multi-beam arrays. The challenge is to develop receivers and wide bandwidth data transport systems which are lower cost, more compact, more reliable, lower weight, and more reproducible than the best current systems, with no compromise to performance. This can be achieved with a greater degree of component integration, extensive use of digital signal processing and transport, and replacement of functions currently performed ...

    This paper focuses on the next detectors for gravitational wave astronomy which will be required after the current ground based detectors have completed their initial observations, and probably achieved the first direct detection of gravitational waves. The next detectors will need to have greater sensitivity, while also enabling the world array of detectors to have improved angular resolution to allow localisation of signal sources. Sect. 1 of this paper begins by reviewing proposals for the next ground based detectors, and presents an analysis of the sensitivity of an 8 km armlength detector, which is proposed as a safe and cost-effective means to attain a 4-fold improvement in sensitivity. The scientific benefits of creating a pair of such detectors in China and Australia is emphasised. Sect. 2 of this paper discusses the high performance suspension systems for test masses that will be an essential component for future detectors, while sect. 3 discusses solutions to the problem of Newtonian noise which ari...

    We examined the clinical safety and efficacy of F105 in 11 subjects with moderate dyslipidemia. F105 is a combination of bergamot fruit extract (Citrus bergamia, BFE) and 9 phytoextracts selected for their ability to improve the antioxidant and anti-inflammatory activity of BFE. In vitro F105 exhibited a synergistic inhibition of oxygen radical absorbing capacity, peroxynitrite formation, and myeloperoxidase activity. Following 12 weeks of F105 daily, no treatment-related adverse events or changes in body mass were seen. Statistically significant changes were noted in total cholesterol (-7.3%), LDL-cholesterol (-10%), non-HDL cholesterol (-7.1%), cholesterol/HDL (-26%), and apolipoprotein B (-2.8%). A post hoc analysis of 8 subjects with HbA1c > 5.4 and HOMA-IR score > 2 or elevated triglycerides revealed additional statistically significant changes in addition to those previously observed in all subjects including triglycerides (-27%), oxLDL (-19%), LDL/HDL (-25%), triglycerides/HDL (-27%), oxLDL/HDL (-25%), and PAI-1 (-37%). A follow-up case report of a 70-year-old female patient, nonresponsive to statin therapy and placed on F105 daily, demonstrated improved cardiometabolic variables over 12 weeks similar to the subgroup. In summary, F105 was clinically well-tolerated and effective for ameliorating dyslipidemia in subjects with moderate cardiometabolic risk factors, particularly in the individuals with HbA1c > 5.4%.

    We explore a variety of examples of music inspired by serious astronomy (as opposed to simply an astronomical title or quick allusion to spooning in June to the light of the Moon). The examples are drawn from my recently published catalog of 133 such pieces, including both classical and popular genres of music. We discuss operas based on the life and work of astronomers, six songs based on a reasonable understanding of the properties of black holes, constellation pieces written by composers from around the world who are or were active amateur astronomers, the song that compares walking on the Moon to being in love, the little-known rock song that became a reference in the Astrophysical Journal, pieces that base the patterns of the music on the rhythms of astronomical phenomena, and a number of others.

    Brown, Ari D.; Chuss, David T.; Chervenak, James A.; Henry, Ross M.; Moseley, s. Harvey; Wollack, Edward J.

    2010-01-01

    We have designed, fabricated, and tested compact radiative control structures, including antireflection coatings and resonant absorbers, for millimeter through submillimeter wave astronomy. The antireflection coatings consist of micromachined single crystal silicon dielectric sub-wavelength honeycombs. The effective dielectric constant of the structures is set by the honeycomb cell geometry. The resonant absorbers consist of pieces of solid single crystal silicon substrate and thin phosphorus implanted regions whose sheet resistance is tailored to maximize absorption by the structure. We present an implantation model that can be used to predict the ion energy and dose required for obtaining a target implant layer sheet resistance. A neutral density filter, a hybrid of a silicon dielectric honeycomb with an implanted region, has also been fabricated with this basic approach. These radiative control structures are scalable and compatible for use large focal plane detector arrays.

    While tunable filters are a recent development in night time astronomy, they have long been used in other physical sciences, e.g. solar physics, remote sensing and underwater communications. With their ability to tune precisely to a given wavelength using a bandpass optimized for the experiment, tunable filters are already producing some of the deepest narrowband images to date of astrophysical sources. Furthermore, some classes of tunable filters can be used in fast telescope beams and therefore allow for narrowband imaging over angular fields of more than a degree over the sky.

    2011-09-01

    The COSPAR President on April 20, 2010 appointed the "Future of Space Astronomy” Working Group under the aegis of Commission E, with the aim to analyze the difficult situation of space astronomy over the next two decades and recommend ways to improve the prospects. Having assessed the scientific needs and the current plans of the main space agencies worldwide, the WG has identified some major concerns about the lack of a secured future for Space Astronomy. In fact, astronomers today have access to an impressive set of space missions and ground-based observatories that gives them nearly continuous coverage of the electromagnetic spectrum from the gamma-ray to the radio regions. But the picture becomes concerning and critical in the next 10 - 15 years, when current space astronomy missions will have ended and new missions will be much less numerous. Astronomy is a difficult observational science requiring continuous and simultaneous access to the full electromagnetic spectrum to explore our complex Universe and to pursue answers to fundamental scientific questions. The history of space astronomy, especially the past three decades, has demonstrated clearly the importance and benefits of access to the gamma-ray, X-ray, UV-optical, near IR and far-IR spectrum from space. So far the only planned observatory class missions, proposed to NASA-ESA-JAXA are JWST (2018), WFIRST/EUCLID (2018-2020), Athena (ex IXO, 2022) and LISA.

    2003-11-01

    On December 1 to 3, the city of Munich (Bavaria, Germany) will be the venue for a "Workshop on Large Scale Programmes and Projects in Astronomy and Astrophysics" organised by the Organisation for Economic Co-operation and Development (OECD) Global Science Forum in co-operation with the European Southern Observatory (ESO). The Workshop will be chaired by Ian Corbett (ESO). The Global Science Forum brings together science policy officials from the OECD countries. The delegates, who meet twice a year, look at a range of generic issues in science funding and seek to identify and maximise opportunities for international co-operation in basic scientific research. This Workshop was proposed by Germany and agreed by the delegates to the Global Science Forum in June. Government officials and scientists will be able to review in detail the information and the observational and technological advances needed for major progress in the field during the next 15- 20 years. The research subjects reviewed will cover the full range from planets, solar systems, life in the Universe, stars, galaxies, extreme objects to cosmology. Related technological challenges, virtual observatories and other data handling issues will also be considered. The primary objective is to specify the policy issues relating to priority-setting, planning, funding and, above all, international co-ordination and co-operation. The Workshop will focus on issues relevant to the process through which astronomy advances, and will highlight means to enhance that process in light of longer-term scientific and political trends. There will probably be a follow-up meeting early in 2004, from which a policy level report will be prepared for consideration by the Global Science Forum and so transmitted to governments. Eighteen delegations, from non-OECD as well as OECD countries, will attend, each consisting of senior programme managers from the national ministry, funding agency or research council, and one or more senior

    All sciences, including astronomy, are now entering the era of information abundance. The exponentially increasing volume and complexity of modern data sets promises to transform the scientific practice, but also poses a number of common technological challenges. The Virtual Observatory concept is the astronomical community's response to these challenges: it aims to harness the progress in information technology in the service of astronomy, and at the same time provide a valuable testbed for information technology and applied computer science. Challenges broadly fall into two categories: data handling (or "data farming"), including issues such as archives, intelligent storage, databases, interoperability, fast networks, etc., and data mining, data understanding, and knowledge discovery, which include issues such as automated clustering and classification, multivariate correlation searches, pattern recognition, visualization in highly hyperdimensional parameter spaces, etc., as well as various applications of ...

    2012-10-01

    This paper focuses on Science, Technology and Society around Astronomy an approach which authors call STS-Astro. It is considered that Astronomy is beyond the limits of Science itself, since it forwards to profound reflections on the own existence, predicated on the philosophical foundation of the Universe which is based on the anthropic principle. Subsequently, it discuss about the International Year of Astronomy 2009 in Brazil and their results. In 2003, Brazil, Italy and France sent a petition to the United Nations Educational, Scientific and Cultural Organization-UNESCO to consider 2009 as the International Year of Astronomy, on the occasion of 400 years of the first telescopic observations made in 1609 by Galileo Galilei (1568-1742). The International Year of Astronomy 2009 involved more than 148 countries and 815 million people, causing an unprecedented integration in the History between areas scientific, technological and humanities. Brazil had an outstanding performance, but even after a few years, numerous data in the country are still subject to studies and analyzes. The positive impacts on various sectors of the society have become permanent and aggregate actions in many institutions as schools, Universities, Observatories, Planetariums, Science Museums and the Astronomy Club, among others.

    On a time scale of years to decades, gravitational wave (GW) astronomy will become a reality. Low frequency (nanoHz) GWs are detectable through long-term timing observations of the most stable pulsars. Radio observatories worldwide are currently carrying out observing programmes to detect GWs, with data sets being shared through the International Pulsar Timing Array project. One of the most likely sources of low frequency GWs are supermassive black hole binaries (SMBHBs), detectable as a background due to a large number of binaries, or as continuous or burst emission from individual sources. No GW signal has yet been detected, but stringent constraints are already being placed on galaxy evolution models. The SKA will bring this research to fruition. In this chapter, we describe how timing observations using SKA1 will contribute to detecting GWs, or can confirm a detection if a first signal already has been identified when SKA1 commences observations. We describe how SKA observations will identify the source(s...

    2016-12-01

    It is known that in the educational system of republic the astronomy is not taught as a separate subject. Moreover, there are no telescopes in the vast majority of schools. "Goodricke John" NGO of amateur astronomers tries to fill this gap by organizing practical lessons of astronomy in secondary schools. NGO is equipped with high quality portable amateur telescopes and organizes periodic mass observations of planets, Moon, star clusters, nebulae in Yerevan and in regions. In addition, mass observations of rare astronomical phenomena are organized, such as the transit of Venus and Mercury across the disk of the Sun. Being the only NGO of amateur astronomers, it has a goal to contribute to publicizing astronomical knowledge and to ensure the availability of astronomical equipment, telescopes also to those segments of the society who have no opportunity to deal with them, in particular, persons with disabilities, prisoners, persons with disabilities, prisoners, soldiers, children from orphanages, school children and others.

    2016-01-01

    Abstract: IceCube's discovery of a diffuse flux of astrophysical neutrinos started a new era of neutrino astronomy.I will review the multiple diffuse analyses in IceCube that observe the astrophysical flux, and what each can tell us. Then I will focus on spatial analyses that aim to identify the sources of such astrophysical neutrinos. This will be followed by an attempt to reconcile all results to draw a coherent picture that is the state of neutrino astronomy. Current plans for a streamlined real-time alert system to promote multi-messenger observations, and future plans of new detectors at the South Pole will be discussed to map out a path for discovering the first high-energy neutrino source in the sky.

  3. An international scope of the regional journal Baltic Astronomy

    Bartasiute, Stanislava

    2015-08-01

    The internationalization of publishing has been progressing in most fields of science, including astronomy and physics in particular. Along with high quality journals having a completely international readership, national and regional journals represent a significant part in number, whereas their average impact is very diverse and not always competitive. Based mainly on the Web of Science data, we will give a comparative analysis of astronomy journals published in/for countries with relatively small astronomical communities, such as Baltic and some Eastern European. Bibliometric statistics will be presented of one of such journals, Baltic Astronomy, established in 1992 as a result of cooperation between astronomers of Latvia, Lithuania, and Estonia. Since the first years of publishing this journal has been evolving from regional to the more internationalized status. The list of countries of contributing authors has expanded to 54, while only 19% of the articles are from the three Baltic countries, mainly from Lithuania (14%) and, to a much lesser extent, from Estonia (3%) and Latvia (2%). Recognizing the inadequacies of national and regional bases for dissemination and exchange of scientific information, the Baltic astronomical communities themselves move, however, towards internationalization: in international journals Latvia publishes twice and Estonia nearly ten times more articles than they do in Baltic Astronomy. Meanwhile Lithuanian astronomers publish nearly the same number of articles both outside and inside the region. In the light of progress being made toward consolidation of scholarly publications, a choice between a national/regional and international basis for publishing is becoming more decisive for the future of national and regional astronomy journals.

  4. Astronomy Education & Outreach in South Africa

    Throop, Henry B.

    2015-11-01

    Although South Africa has evolved greatly in the 20 years since the end of apartheid, it remains a very divided country. The highest-performing students are comparable in ability to those in the US and Europe, but nearly all of these students are from priveleged Afrikaaner (European) backgrounds. The vast majority of students in the country are native African, and school standards remain very low across the country. It is common that students have no textbooks, teachers have only a high school education, and schools have no telephones and no toilets. By high school graduation, the majority of students have never used a web browser -- even students in the capital of Johannesburg. And while a few students are inspired by home-grown world-class projects such as the Square Kilometer Array (SKA) and Southern African Large Telescope (SALT), most remain unaware of their existence.Despite the poor state of education in the country, students work hard, are curious, and desire information from the outside world. Astronomy is one subject in which students in rural Africa often show exceptional interest. Perhaps astronomy serves as a 'gateway science,' linking the physically observable world with the exotic and unknown.Here I report on many visits I have made to both rural and urban schools in South Africa during the 2013-2015 period. I have interacted with thousands of grade 7-12 students at dozens of schools, as well as taught students who graduated from this system and enrolled in local universities. I will present an assessment of the state of science education in South Africa, as well as a few broader suggestions for how scientists and educators in developed countries can best make an impact in Southern Africa.

    Selection from past astronomy education, activities, textbooks and curricula will be presented. Didactic aspects and comparison with physics education will be exemplified. The astronomy/science education along the time in Romania was roughly divided in four directions: very broad information texts for everybody, popular science, school textbooks, science fictions and astronomy/science literature, and exemplified using original texts. All categories were intended to extend literacy in science, but in different ways. The trends for different periods were outlined. The teaching of astronomy and astrophysics in high school and universities, with special attention to the Faculty of Physic from University of Bucharest are presented. Suggestions for future improvement of both related fields, physics and astronomy, will be one of the outcomes of our communication.

  8. Internet Exercises as a Means of Integrating Late-breaking Astronomy News Into the Introductory Course

    Science.gov (United States)

    English, T.

    1997-12-01

    Astronomy is a dynamic science, a point that is sometimes lost on students who slog through the standard treatment of the introductory astronomy course. By integrating the easy access to current research information afforded by the internet and other media, it is possible to tailor the introductory course so that students gain a greater appreciation of the ever-changing landscape of scientific knowledge. For the rest of their lives, the students now taking our courses will be informed of astronomical discoveries through the mass media, which increasingly includes the internet. Through design of assignments that ask students to confront the presentation of late-breaking astronomy news, the introductory astronomy course can help students to be able to process such information long after they have graduated. Caton has taken this idea to an extreme, developing a nonlinear, topics-driven approach to teaching the introductory course (Mercury, 25.6, p.29). Some may be unwilling to suspend the traditional course structure to take such an approach, but there are alternatives. The internet provides easy access to a wider range of breaking astronomy news. Several science news services are available, and many astronomy-related sites offer regular updates. Direct sources for press releases are also easily found. With such access, students can follow stories as they develop. The key to achieving this is through design of assignments that force the students to look for the latest information online. Several variations have been tried at Gardner-Webb, mostly involving student construction of web browser documents that profile particular stories. These assignments build student skills in online research, and communicate that astronomy is an evolving science. Hopefully, they also instill a confidence that allows individual analysis of astronomy (and indeed all science) stories in the news for years to come - well after the specific details of the astronomy course are forgotten.

    2016-01-01

    Skynet Junior Scholars (SJS), funded by the National Science Foundation, aims to engage middle school youth from diverse audiences in investigating the universe with research quality robotic telescopes. SJS project development goals include: 1) Online access to optical and radio telescopes, data analysis tools, and professional astronomers, 2) An age-appropriate web-based interface for controlling remote telescopes, 3) Inquiry-based standards-aligned instructional modules. From an accessibility perspective, the goal of the Skynet Junior Scholars project is to facilitate independent access to the project by all youth including those with blindness or low vision and those who are Deaf or Hard of Hearing.Deaf and Hard of Hearing (DHH) students have long been an underserved population within STEM fields, including astronomy. Two main barriers include: (1) insufficient corpus of American Sign Language (ASL) for astronomy terminology, and (2) DHH education professionals who lack astronomy background. A suite of vocabulary, accessible hands-on activities, and interaction with trained professionals, are critical for enhancing the background experiences of DHH youth, as they may come to an astronomy lesson lacking the basic "incidental learning" that is often taken for granted with hearing peers (for example, from astronomy in the media).A collaboration between the Skynet Junior Scholars (SJS) project and the Wisconsin School for the Deaf is bringing astronomy to the DHH community in an accessible way for the first time. We follow a group of seven DHH youth over one semester as they interact with the SJS tools and curriculum to understand how they assimilate astronomy experiences and benefit from access to telescopes both directly (on school campus and at Yerkes Observatory) and through Skynet's robotic telescope network (optical and radio telescopes, inquiry-based modules, data analysis tools, and professional astronomers). We report on our first findings of resources and

  11. Why Astronomy Should BE Part of the School Curriculum

    Science.gov (United States)

    Percy, John

    Why is astronomy useful? Why should it be supported by taxpayers? Why should it be part of the school curriculum? In this paper I will list 20 reasons. They include: cultural historical and philosophical reasons; practical technological and scientific reasons; environmental aesthetic and emotional reasons; and pedagogical reasons. Astronomy can attract young people to science and technology. It can promote public awareness understanding and appreciation of science. It can be done as an inexpensive hobby; ""the stars belong to everyone"". Finally: I will connect the 20 reasons to the expectations of the modern school curriculum: knowledge skills applications and attitudes. In the context of the science curriculum this includes science technology society and environment.

    Variable Star Network (VSNET, http://www.kusastro.kyoto-u.ac.jp/vsnet/) is a global professional-amateur network of researchers in variable stars and related objects, particularly in transient objects, such as cataclysmic variables, black hole binaries, supernovae and gamma-ray bursts. The VSNET has been playing a pioneering role in establishing the field of "transient object astronomy", by effectively incorporating modern advance in observational astronomy and global electronic network, as well as collaborative progress in theoretical astronomy and astronomical computing. The VSNET is now one of the best-featured global networks in this field of astronomy. We review on the historical progress, design concept, associated technology, and a wealth of scientific achievements powered by the VSNET.

  13. Astronomy at the service of the Islamic society

    Science.gov (United States)

    Fernini, Ilias M.

    2011-06-01

    The Islamic society has great ties to astronomy. Its main religious customs (start of the Islamic month, direction of prayer, and the five daily prayers) are all related to two main celestial objects: the Sun and the Moon. First, the start of any Islamic month is related to the actual seeing of the young crescent after the new Moon. Second, the direction of prayer, i.e., praying towards Mecca, is related to the determination of the zenith point in Mecca. Third, the proper time for the five daily prayers is related to the motion of the Sun. Everyone in the society is directly concerned by these customs. This is to say that the major impetus for the growth of Islamic astronomy came from these three main religious observances which presented an assortment of problems in mathematical astronomy. To observe these three customs, a new set of astronomical observations were needed and this helped the development of the Islamic observatory. There is a claim that it was first in Islam that the astronomical observatory came into real existence. The Islamic observatory was a product of needs and values interwoven into the Islamic society and culture. It is also considered as a true representative and an integral par of the Islamic civilisation. Since astronomy interested not only men of science, but also the rulers of the Islamic empire, several observatories have flourished. The observatories of Baghdad, Cairo, Córdoba, Toledo, Maragha, Samarqand and Istanbul acquired a worldwide reputation throughout the centuries. This paper will discuss the two most important observatories (Maragha and Samarqand) in terms of their instruments and discoveries that contributed to the establishment of these scientific institutions.

    Torres, J. R. F.

    2009-03-01

    The formal academic programs in Astronomy of the Rizal Technological University are the first such programs in the Philippines. The Master of Science in Astronomy program is envisioned to provide the student with a wide range of knowledge in many areas of Astronomy, leaning towards the descriptive aspects of knowledge. The student will choose the field or research most suitable to his or her interests. Three of these researches done while enrolled in the program, and even researches completed before the student actually enrolled in the program, may be considered as his or her thesis. The program suits professionals in all persuasions who wish to study Astronomy either for professional advancement or plainly for the love of the science or for intellectual satisfaction. Non-science majors can enroll. In 2008, the RTU Graduate School decided to ladderize the MS program and the Graduate Diploma in Astronomy was designed. This program is suited for science educators, astronomy lecturers and entrepreneurs, members of astronomical societies, and plain astronomy enthusiasts who like to gain in-depth knowledge in the most important aspects of astronomy. A bachelor's degree in any field is required. The program can be finished in two semesters and one summer. If the student opts to continue in the MS in Astronomy program, all the courses he or she has earned in the Diploma will be credited. The Bachelor of Science in Astronomy Technology is an intensive baccalaureate degree program designed to prepare students to become future research scientists and technologists in the field of Astronomy. The BS in Astronomy Technology is a cross-fertilized program, integrating interrelated sciences, such as engineering, geology, remote sensing, physics, atmospheric and environmental science, biology and biochemistry, and even philosophy and entrepreneurship into the study. Thus, the B.S. in Astronomy Technology program gives the student excellent job opportunities in many fields.

    2011-12-01

    An enigmatic prediction of Einstein's general theory of relativity is gravitational waves. With the observed decay in the orbit of the Hulse-Taylor binary pulsar agreeing within a fraction of a percent with the theoretically computed decay from Einstein's theory, the existence of gravitational waves was firmly established. Currently there is a worldwide effort to detect gravitational waves with inteferometric gravitational wave observatories or detectors and several such detectors have been built or are being built. The initial detectors have reached their design sensitivities and now the effort is on to construct advanced detectors which are expected to detect gravitational waves from astrophysical sources. The era of gravitational wave astronomy has arrived. This article describes the worldwide effort which includes the effort on the Indian front— the IndIGO project —, the principle underlying interferometric detectors both on ground and in space, the principal noise sources that plague such detectors, the astrophysical sources of gravitational waves that one expects to detect by these detectors and some glimpse of the data analysis methods involved in extracting the very weak gravitational wave signals from detector noise.

  20. [JAN JĘDRZEJEWICZ AND EUROPEAN ASTRONOMY OF THE 2ND HALF OF THE 19TH CENTURY].

    Science.gov (United States)

    Siuda-Bochenek, Magda

    2015-01-01

    Jan Jędrzejewicz was an amateur astronomer who in the 2nd half of the 19th century created an observation centre, which considering the level of research was comparable to the European ones. Jędrzejewicz settled down in Plonsk in 1862 and worked as a doctor ever since but his greatest passion was astronomy, to which he dedicated all his free time. In 1875 Jędrzejewicz finished the construction of his observatory. He equipped it with basic astronomical and meteorological instruments, then began his observations and with time he became quite skilled in it. Jędrzejewicz focused mainly on binary stars but he also pointed his telescopes at the planets of the solar system, the comets, the Sun, as well as all the phenomena appearing in the sky at that time. Thanks to the variety of the objects observed and the number of observations he stood out from other observers in Poland and took a very good position in the mainstream of the 19th-century astronomy in Europe. Micrometer observations of binary stars made in Płońsk gained recognition in the West and were included in the catalogues of binary stars. Interest in Jędrzejewicz and his observatory was confirmed by numerous references in the English "Nature" magazine.
