Astronomy - Wikipedia, the free encyclopedia Astronomy (Greek: αστρονομία = άστρον + νόμος, astronomia = astron + nomos, literally, "law of the stars") is the science of celestial objects and phenomena that originate outside Earth's atmosphere, such as stars, planets, comets, galaxies, and the cosmic background radiation. Astronomy is not to be confused with astrology, which assumes that people's destiny and human affairs in general are correlated to the apparent positions of astronomical objects in the sky -- although the two fields share a common origin, they are quite different; astronomers embrace the scientific method, while astrologers do not. Optical astronomy is the part of astronomy that uses optical components (mirrors, lenses, CCD detectors and photographic films) to observe light from near infrared to near ultraviolet wavelengths. en.wikipedia.org /wiki/Astronomy   (1821 words)

Stellar astronomy - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-21) Stellar astronomy is the study of stars and the phenomena exhibited by the various forms/developmental stages of stars. Even the detection of gravitons or neutrinos could fall under the rubric of "observational stellar astronomy," although those sorts of observations generally have more specialized subfields of their own. Theoretical stellar astronomy includes various forms of stellar modeling as well as models of specific phenomena which have been observationally associated with stars (such as magnetic reconnection models for stellar flares or Raymond-Smith models for high-temperature plasmas which may surround stars or which may be found in other astronomical contexts). www.bucyrus.us /project/wikipedia/index.php/Stellar_astronomy   (172 words)

Extragalactic astronomy - Wikipedia, the free encyclopedia Extragalactic astronomy is the branch of astronomy concerned with objects outside our own Milky Way Galaxy (the study of all astronomical objects which are not covered by galactic astronomy). It is therefore useful to sub-divide this branch into Near-Extragalactic Astronomy and Far-Extragalactic Astronomy. The former deals with objects such as the galaxies of our Local Group, which are close enough to allow very detailed analyses of their contents (e.g. en.wikipedia.org /wiki/Extragalactic_astronomy   (125 words)

SBoughn.html While my research activities have moved to extragalactic astronomy and cosmology, I still have an interest in gravitational radiation and general relativity (I teach a course on the latter, Physics 311a). More recently, I have been interestedin the large-scale structure in the universe and, in particular, the "dark matter" and "dark energy" that are currently thought to comprise 95% of the energy content of the universe. Typically 2 to 3 students are employeed each summer as research assistants and many of these continue working on the projects during the academic year (Astro 404a,b) as a part of their senior research experience. www.haverford.edu /physics-astro/Boughn/SBoughn.html   (424 words)

Extragalactic Astronomy / Cosmology The majority of my time is currently spent on the development of laser guided adaptive optics systems, so I do most of my work in extragalactic astronomy by directing the research of Ph.D. thesis students. My two most-advanced graduate students in extragalactic astronomy are Ian Barton and Michelle Griffin. The galaxy redshift surveys in rich clusters progressed rapidly, but one big fly appeared in the ointment when, in 1972, William Tifft published a paper in the Astrophysical Journal (Tifft 1972) claiming to find discrete bands in a diagram in which galaxy redshift was plotted against galaxy magnitude for a sample of Coma cluster galaxies. www.astro.uiuc.edu /~thompson/extrag.html   (3629 words)

Extragalactic Astronomy and Cosmology Observational extragalactic astronomy has traditionally been one of the main themes of research at the Bologna Observatory. It includes a wide range of subjects, from the structure and evolution of ``normal" galaxies, to the physical properties of active galactic nuclei (AGNs) to observational cosmology. The extragalactic research at the Bologna Observatory is characterized by a multiwavelength approach: while optical astronomy is the main field at the Observatory, some of the scientific staff specialize in X-ray observations of AGNs, and others find their main interest in radio studies of galaxies and quasars. www.bo.astro.it /report03/node28.html   (244 words)
