These latest findings from Hubble will appeal to anyone with even a passing interest in astronomy. The first focuses on collisions between galaxies within Stephan's Quintet that have given rise to star clusters and dwarf galaxies. This release includes an introduction, background information, stunning photos, animations, videos, related links, and more.

NASA's well known High Energy Astrophysics Learning Center has created an astronomy site just for kids. StarChild, still under construction at this time, contains sections on the solar system, the universe, and "space stuff" (astronauts, space travel, and the Hubble Space Telescope, among others). It also includes a glossary with brief explanations of astronomy-related terms. The site is...

This site from Jim Kaler, a Professor of Astronomy at the University of Illinois, is geared toward amateur and budding astronomers. Kaler offers detailed but non-technical descriptions of selected stars and a link to a photo of their respective constellations. Another section of the site, The Natures of Stars, consists of basic overviews of key concepts. The star descriptions are interesting to...

Built and operated by the National Astronomical Observatory of Japan, the Subaru Telescope sits atop Mauna Kea on Hawaii's Big Island. With a 24-ton mirror, the largest single-piece glass mirror ever used in a telescope, Subaru has produced infrared images as clear and striking as astronomers have been receiving from the Hubble Space Telescope. On January 28, 1999, the director and staff at Subaru...

One of three divisions within the Office of Space Science at NASA, the Sun-Earth Connection has the primary goal of understanding the Sun, Heliosphere, and planetary environments as a single connected system. The Web site offers visitors information on space science missions including the Living with a Star and Solar Terrestrial Probes mission. Meeting notes and official reports can be viewed...

Part of the Institute for Astronomy at the University of Edinburgh, the Wide-Field Astronomy Unit maintains the SuperCosmos Sky Surveys Web site. The SuperCosmos is an advanced photographic plate-digitizing machine that produces data derived from the scans of photographic Schmidt survey plates. Visitors can "extract images (pixel data) up to 15 arcmin across and/or object catalogues covering up to...

Based in Geneseo, New York, the American Meteor Society (AMS) is a nonprofit organization dedicated to supporting meteoritical research by both amateur and professional astronomers. The AMS Website provides weekly updates on observed meteor activity, a section of logs and images of fireball sightings, and overviews of and resources for both visual and radio observations. A highlight of the site is...
