The Sky Map
This astronomical survey by the Sloan organization, when completed, will provide detailed images covering more than a quarter of the sky, and almost a million galaxies and quasars. Although the site is meant to be interactive, a mandatory first stop is the Getting Started segment to learn how to make best use of the site's features.
