There's a moon in this picture. Do you see it? You're going to want to look at the enlarged image. See the white dot? That's Saturn's moon Atlas, measuring a tiny 32 km (20 miles) across. Thanks to its gravity, Atlas has cleared out the space between Saturn's A and F rings.
Of course, this photograph was taken by NASA's Cassini spacecraft as part of its ongoing work at Saturn. It took the image on April 29, 2007 when it was approximately 1.8 million km (1.1 million miles) from Atlas.
