Astronomy Picture Of The Day Calendar

ATTENTION: Night-Sky programs are starting to be offered again, staff permitting. Please call the Visitor Center for more information. (505) 786-7014

Chaco's Night Sky Initiative: Since 1991, Chaco Culture NHP has offered astronomy in its public interpretive programs. Programs emphasize the practices of the Chacoan people a thousand years ago, as well as modern approaches to viewing the same night sky they viewed--in a remote environment with clear, dark skies, and free from urban light pollution.

The park established an on-going partnership with the Albuquerque Astronomical Society (TAAS) in 1991. In January 1997, TAAS member John Sefick brought his astronomy equipment to Chaco. He was so impressed with the skies above Chaco that he donated a domed observatory and equipment to the park.

The Chaco Night Sky Program: The park began constructing a permanent observatory at the visitor center in 1997. In May 1998, the park dedicated the Chaco Observatory. The observatory added a new dimension to Chaco's interpretation of astronomy and now serves many different people:

April through October:

Evening night sky programs are usually presented during the summer months, dependent on staff availability. Please view the calendar for specific program dates and times. The programs usually begin with staff presentations on archaeoastronomy, cultural history, and other topics, and are followed by telescope viewing of celestial objects.

The ESO education and Public Outreach Department (ePOD) supports science communicators, and especially those communicating astronomy with the public through different products and activities. This page gathers these resources together.

Dr. Ken Kremer is a speaker, research scientist, freelance science journalist (Princeton, NJ) and photographer whose articles, space exploration images and Mars mosaics have appeared in magazines, books, websites and calendars including Astronomy Picture of the Day, NBC, BBC, SPACE.com, Spaceflight Now and the covers of Aviation Week & Space Technology, Spaceflight and the Explorers Club magazines. Ken has presented at numerous educational institutions, civic & religious organizations, museums and astronomy clubs. Ken has reported first hand from the Kennedy Space Center, Cape Canaveral, NASA Wallops, NASA Michoud/Stennis/Langley and on over 40 launches including 8 shuttle launches. He lectures on both Human and Robotic spaceflight - www.kenkremer.com. Follow Ken on Facebook and Twitter.

Although published literature about San Lus is sparse, more than 2,000 pages of unpublished letters and 40 photographs survive in the archives of Dudley, Lick, and the Carnegie Institution. The presentation will recount the grand astrophysical goal of extending positional astronomy to the southern skies, and will suggest that staff dissension at San Lus might be illuminated by literature about the psychology of isolation and confinement in polar and space expeditions.

Recent research on young children's beliefs about observational astronomy (Vosniadou & Brewer, 1992, 1994) has revealed a very rich developmental picture. Children age 6 to 9 years believe that the earth is a flat, stationary object and that the day/night cycle is caused by occlusion mechanisms such as clouds coming in front of the sun or movement mechanisms such as moving down behind mountains.

To test theories one needs an interface between symbolic representations and the real world. Observations, experiments, and the technological means that facilitate them, provide this interface. No matter how intuitively appealing and mathematically advanced a physical theory may be, it only enters the domain of standard physical science when confronted, tested, checked, and if necessary modified and even rejected by the measure of the real world that observations and experiments provide. Thus when, in 1610, Galileo Galilei (1564-1642) introduced the telescope as a scientific instrument into astronomy, Kepler did not ignore the link established by Galileo between the theory underpinning the telescope and the instrument's usage. The event proved of singular importance for the course of modern science.

In this context the question as to whether practice preceded theory has so far remained unsettled. The first objective of this research project is to document in detail and analyze the complex relations that subsist between theory and instrument at the time of the introduction of the telescope. By critically tracing the origin of the theory of the telescope and the incipient insight that placed an instrument between the naked eye and an object, we expect our research to open up novel perspectives on the history of optics and astronomy. The second objective is wider and more important. The introduction of the telescope poses a fundamental question in the historiography of the development of modern science: how are we to understand a scientific instrument as an object that encapsulates knowledge that is not of propositional nature?

SAL personnel were among the first to conduct research in the field of ultraviolet space astronomy. Starting with Aerobee sounding rockets and NASA's X-15 rocket plane, these investigations led toward the successful design, construction, launch, and operation of the Orbiting Astronomical Observatory (OAO-2) spacecraft, the first remotely-operated space observatory.

A survey of the orientations of 130 Medieval English Village revealed that these orientations did not reflect either the indigenous calendric emphasis on the mid-quarter days or the Greek emphasis on the geometrically determined equinoxes and solstices. Instead these orientations can best be defined in terms of Roman calendric principles, as those principles were elaborated in Medieval computistical texts. This emphasis on locally elaborated Roman calendric principles in the orientation of churches suggests a parallel to the elaboration of Roman astronomical texts found in a range of Carolingian and later astronomical manuscripts. These two strands of evidence suggest that early medieval astronomy owes much more to its Roman heritage than it does to the Romans' Greek sources.

Are historians of astronomy and what we might call anthropologists of astronomy still as far apart as ever? Does archaeoastronomy have any real insights to offer historians of astronomy, and is the reverse true? To what extent is theoretical and procedural integration possible, beneficial, or even desirable?

Finally, lava flows from Kilauea have been causing some problems, closing a popular viewing site. A home in Kalapana might be in the path of the lava flow as well. You can see a great picture of the lava flow overtaking a Highway 130.

Black hole feeding, visible as quasars, is a critical ingredient in many fields from galaxy evolution to multi-messenger gravitational wave astrophysics. Despite their prodigious luminosities, the important emission regions surrounding the supermassive black hole the accretion disk and broad line region cannot be imaged directly because of their small angular sizes. Because quasars are intrinsically variable phenomena, time-domain spectroscopy is a powerful tool for revealing their nature. Single-epoch spectroscopy has been a workhorse for building the modern picture of quasar central engines. Extending this to the time domain promises new insights and exotic discoveries.

Dr. Runnoe will describe two examples from her work on quasars in the time domain: an observational search for supermassive black hole binaries, an expected but unobserved product of galaxy evolution, and changing-look quasars, newly observed rapid transitions between "quasar-like" and "galaxy-like" spectral states. With ongoing and new big-data facilities like the Sloan Digital Sky Survey and Large Synoptic Survey Telescope, the future is bright for our understanding of quasars in the upcoming era of time-domain astronomy.

From the generation of gold to the expansion rate of the Universe: With the detection of compact binary coalescences and their electromagnetic counterparts by gravitational-wave detectors, a new era of multi-messenger astronomy has begun. In this talk, Professor Coughlin will describe how GW170817, our first example in this new class, is being used to study a diverse variety of dense matter in the Universe and how fast the Universe is expanding. He will then discuss how we are using telescopes to look for more of them and developing models to test what we find. Professor Coughlin will close with future prospects for this new field. 2351a5e196
