After turning millions of Internet users into virtual explorers of the world with Google Earth, the Internet search giant is now hoping to turn many of them into virtual stargazers.
Today Google unveiled a service called Sky that allows users to view the skies as seen from Earth. Like Google Earth, Sky lets users fly around and zoom in, exposing increasingly detailed imagery of some 100 million stars and 200 million galaxies.
The Sky imagery was stitched together from more than 1 million photographs from scientific and academic sources. Google said that it developed the project strictly because some of its engineers were interested in it, and that it had no plans to make money from it for now.
Sky already has layers showing various constellations, a users guide to galaxies, the position of planets two months into the future and animations of lunar positions To get Sky, you have to download the latest version of GoogleEarth.
