TO THE MOON, ALICE!

Ever wonder how the moon got there? Now we know (almost). According to new evidence to be published Friday in the journal Science, the moon probably drifted into the solar system billions of years ago, then bounced violently off the Earth before settling into orbit. Though the "giant-impact" theory is old, new data from a lunar research satellite called Clementine indicates that the moon is not made from the same basic material as the Earth. Cheese has been ruled out.
