If you have Google Earth (and if you don't have it, you really need to get it) be sure to download the latest update. Google has teamed with the Space Telescope Science Institute in Baltimore, the science operations center for the Hubble Space Telescope to add Google Sky to the program. In addition to all the Hubble images, it includes images taken by two powerful visible-light surveys, the Digitized Sky Survey and the Sloan Digital Sky Survey. The Digitized Sky Survey contains photographic surveys of nearly the entire sky, with about a million objects. The Sloan survey comprises images of hundreds of millions of much fainter objects and covers more than a quarter of the sky. As with Google Earth, you can travel anywhere you want, magnifying images and virtually traversing light years in a matter of seconds.

If, in your wanderings, you see an icon of the HubbleSite logo, just click on it. Information on the object will appear. Sky in Google Earth also will provide links to the Hubble news database and other Hubble information, including the Hubble Heritage project.
