A lot of people don’t realize that NASA studies the Earth as well as the rest of the universe. Sure, pictures from Hubble and Cassini and the Mars Rovers are spectacular, but there are some great views of our own planet too, many of which are available at NASA’s Earth Observatory site. Today the Big Picture has a selection of some of the best photos of Earth from NASA’s collections. You should really go take a look and find yourself a new computer wallpaper!
