Titan, Epimetheus, and Rings

In 2006 April, the robot Cassini spacecraft captured Saturn's A and F rings stretching in front of cloud-shrouded Titan.  Near the rings and appearing just above Titan was Epimetheus, a moon which orbits just outside the F ring. The dark space in the A ring is called the Encke Gap, although several thin knotted ringlets and even the small moon Pan orbit there.
