Asterices (***) indicate some of the most impressive sites.

NASA has some of the nicest sites in the business. Here's a small selection.

***Hubble Space Telescope
...need I say more?
Mars Pathfinder

Free Programs to Run on Your PC

...some wonderful freeware from John Walker. Includes homeplanet (a very nice planetarium program for Windows), skyscrsv (a screen saver for Windows), solar (an interactive orrery), yoursky (Web-based planetarium), and more.

Professional Utilities

These sites are the ones I use all the time, and are intended primarily for professional astronomers. On the off chance you wish to dive into the professional literature, these are good places to start -- and all are free and open to the public!
The NASA Extragalactic Database
...type in the name of your favorite galaxy (or its coordinates), and get a list of all the related journal articles, catalog entries, magnitude estimates, etc.; as well as the best available position, and an optical finding chart. NASA does it again!
Astronomical Data Center easy way to access computer-readable versions (often simple text) of an amazing number of astronomical catalogs.
Astrophysics Data System the astronomical literature without pawing through all those musty journals. Want to see what that scientist you saw on CNN has been doing? Type in her name and off you go!
