Last Friday, while orbiting Saturn, the Cassini spacecraft turned its camera lens on earth from almost a billion miles away. NASA has released the images, which show not only Saturn and its rings, but also the Earth in the (very far) distance. The original 'raw' images taken by the spacecraft are grayscale, but astronomy enthusiast Valerie Klavans has converted some of them and added color. The results look pretty spectacular. Check them out after the link.
