NASA just released this breathtaking photo of Saturn, seven of its moons, and Earth in the background. Actually a mosaic of 141 wide-angle photos, this stunning view was captured by the Cassini spacecraft while inside Saturn's shadow. The image covers 404,880 miles (651,591 kilometers). According to a NASA report, "This mosaic is special as it marks the third time our home planet was imaged from the outer solar system; the second time it was imaged by Cassini from Saturn's orbit; and the first time ever that inhabitants of Earth were made aware in advance that their photo would be taken from such a great distance."
