Rings Discovered Around a Moon for the First Time

Riding with Robots writes "It turns out that one of the Ringed Planet's moons has rings of its own. The robotic spacecraft Cassini at Saturn has discovered that the icy moon Rhea is orbited by an extensive debris field and at least one ring, the first such system found. 'Many years ago we thought Saturn was the only planet with rings,' said one mission scientist. 'Now we may have a moon of Saturn that is a miniature version of its even more elaborately decorated parent.'"

It's amazing just how much fascinating data these deep solar system probes have gathered. Some are even out of the solar system testing interstellar space. And how many trillions have been spent uselessly collecting dust on Mars? More solar probes please!
