Google Earth Given Celestial View

The constellations of Andromeda, Hydra and Vulpecula are now just a mouse click away for amateur star-gazers, following the launch of Google Sky. The tool is an add-on to Google Earth, a program that allows users to search a 3D rendition of our planet's surface. Sky will allow astronomers a chance to glide through images of more than one million stars and 200 million galaxies.
