If you use Google Earth, you already know what a powerful program it is in finding places around the world, finding directions, and exploring.  It now has a new feature called "Sky", which allows you to view and search the universe.  You can find constellations, different planets, galaxies, and other cool things in outer space.  Just like Google Earth, Google Sky uses satellite images and "stitches" them all together to make a searchable map of the universe.  If you want to learn more, go to this link:
