Rings Arcs Discovered Around Saturn

From - Shaun Saunders sends in an article of a new Cassini spacecraft discovery. NASA's Cassini spacecraft has found two new, partial rings around Saturn that each accompany a small moon. The ring arcs, extend ahead of and behind the small Saturnian moons Anthe and Methone in their orbits. These ring arcs are formed by the gravity of the nearby larger moon Mimas as it tugs on the two smaller moons, first pulling the moons ahead in their orbits and then pulling them back spreading material just ahead and just behind each little moon.
