Google combined Google Maps technology with astronomical data to make a way for users to explore the universe. Google Sky debuted in 2007 and covered 100 million stars and 200 million galaxies.
The service was later packaged into another Lab project, Sky Map for Android. That app uses a smartphone's internals to take things to a whole different level. Here's Google's description of the app: "Point your phone at the sky, and Google Sky Map will show the stars, planets, constellations, and more to help you identify the celestial objects in view." .
