Earth on the Move

In celebration of Earth Day, I thought a cool video of our planet would be appropriate. As the Mercury spacecraft Messenger did a flyby of Earth last year, it took hundreds of photos. They start out around 66,000 kilometers from the planet and go until about 436,000 km. Scientists strung the photos together to create the video, and it was well worth the effort. Check it out here.
