NASA's Cassini spacecraft has discovered a new object in Saturn's rings.

By capitalizing on the angle of sunlight cast on the rings as the planet nears its August 11 equinox, Cassini captured the 25-mile long shadow cast on Saturn's B ring by a tiny moonlet that is probably around 1,300 feet in diameter.
