Saturn Moon May Have Rings

From National Geographic News, Shaun sends in this article:

Rhea, Saturn's second largest moon, may be the first known moon with its own small system of rings. Although no one has actually seen Rhea's rings, scientists say that odd data collected during a 2005 flyby of the Cassini spacecraft provides strong clues. "We can't say definitely that there are rings surrounding Rhea," said planetary scientist Geraint Jones. "But the data we have are a real puzzle, and the only reasonable explanation we've been able to come up with is the debris disk proposal."

Now there is a graphic that I bet we see in some upcoming science fiction movie. Odds on when we see it first?
