Google Earth now allows you to view Stars, Constellations, Planets, Moon, Galaxies, Backyard Astronomy, Hubble Showcase and the life of a star.
To view these heavenly objects, select Switch to Sky from View menu or click Sky button. Then Google Earth presents a view of the Sky. When you switch to Sky, then the current location on Earth is hidden and you will see the Sky above the current location. When you exit Sky, then you return to the same current location.
