AstroWeb: Astronomy/Astrophysics on the Internet Welcome to AstroWeb - a collection of pointers to astronomy-related information available on the Internet. The database is maintained by the AstroWeb Consortium , a collaboration involving 9 individuals at 7 institutions. In addition to classified lists of resource records, the Consortium also provides a utility to search the AstroWeb database: (WAIS search help) Most of the URLs in the database are tested three times a day to verify aliveness (see "AstroWeb Dead URLs" and "AstroWeb Unreliable URLs" ). The Consortium will be pleased to accept contributions of new resource records. You can use HTML forms to submit an addition or change to the Astroweb database review pending submissions review Astroweb records changed in the past month or send EMail to the Consortium This NRAO version of AstroWeb is recomputed at about 09:10 UTC each day, if the master database has been changed. Neither the individuals involved in the AstroWeb Consortium, nor their affiliated institutions, accept any responsibility for the contents or availability of information located at other Internet sites. 1/27/2003 2:57:25 PM The AstroWeb master database currently contains 3086 distinct resource records: Category Records Observing resources Telescopes Astronomical survey projects Telescope observing schedules Metereological information Data Resources Data and Archive Centers Astronomy Information Systems Publication-related Resources Abstracts of Astronomical Publications Full-texts of Astronomical Publications Astronomical Bibliographical Services Astronomy-related Libraries ...

Many astronomers believe supermassive black holes may lie at the center of these galaxies and power their explosive energy output. Tell me about AGN! Tell me more about AGN! angstrom A unit of length equal to 0.00000001 centimeters. This may also be written as 1 x 10 cm (see scientific notation angular momentum A quantity obtained by multiplying the mass of an orbiting body by its velocity and the radius of its orbit. According to the conservation laws of physics, the angular momentum of any orbiting body must remain constant at all points in the orbit, i.e., it cannot be created or destroyed. If the orbit is elliptical the radius will vary. Since the mass is constant, the velocity changes. Thus planets in elliptical orbits travel faster at perihelion and more slowly at aphelion . A spinning body also possesses spin angular momentum. apastron The point of greatest separation between two stars which are in orbit around each other. See
