Google Sky... The constellations of Andromeda, Hydra and Vulpecula are now just a mouse click away for amateur star-gazers, following the launch of Google Sky.
Google Earth combines the power of Google Search with satellite imagery, maps, terrain and 3D buildings to put the world's geographic information at your fingertips.
- Fly to your house. Just type in an address, press Search, and you'll zoom right in.
- Search for schools, parks, restaurants, and hotels. Get driving directions.
- Tilt and rotate the view to see 3D terrain and buildings, or look up to explore the sky
- Save and share your searches and favorites.


Now you can stargaze using Google's popular desktop mapping application Google Earth. In the latest version of Google Earth, hit the "Switch between Sky and Earth" button on the toolbar to get a map of the night sky from your current location. Several Sky layers are listed on the left-hand side, including Constellations, Backyard Astronomy, Hubble Showcase, The Moon, The Planets, User's Guide to Galaxies and Life of a Star. The Sky layers are composed of over 1 million photographs from various scientific and academic sources. Looks like an incredible educational resource for anyone who wanted to be an astronaut when they grew up. Google Earth is a free download for Windows, Mac and Linux.
Users can overlay the night sky with other information such as galaxies, constellations and detailed images from the Hubble Space Telescope.
Imagery for the system came from six research institutions including the Digital Sky Survey Consortium, the Palomar Observatory in California and the United Kingdom Astronomy Technology Centre.
