Cassini Finds Rings in Rhea?

The Cassini spacecraft has apparently detected a ring system in Rhea, Saturn's second biggest moon, during the 2005 flyby. If validated, Rhea's ring system will be the first non-planetary one to be discovered.

Trivia: Rhea was discovered by Giovanni Domenico Cassini, who also discovered the Great Red Spot of Jupiter and the Cassini division.
