Astronomy and
Space-Related Web Sites

Like the real universe, the universe of astronomical information available on the World Wide Web is expanding rapidly. No single list of astronomy-and space-related Web sites can be 100% complete. The following list, compiled and updated regularly by the editors of Sky & Telescope, is geared toward amateur astronomers and space buffs. But it also includes links to other lists of useful resources, so from here you can "click" your way to virtually every interesting celestial site on the Web. (We also have a listing of astronomy-club home pages.) Many museums, planetariums, and small observatories have Web pages too. You'll find them in our Astronomical Directory. Have fun, and please come back often!
