Now this is cool. We know that no one really paid attention in Astronomy class yet everyone always looks up to night sky to see if they can identify any stars, constellations, and/or planets. It's just human nature, really.

But half the time we don't know the Big Dipper from Cassiopeia. Luckily, Google has got us covered. They've just released Sky Map, an Android application that tells you exactly what you're looking at in the night sky. By using a combination of GPS, sensors, and the compass, Sky Map can determine what part of the sky you're looking at and what the name of the stars are. It's really amazing.
