MOONS OF SATURN : Rhea

by Lauren Effron and Dave Mosher

Sadly, Saturn's 949-mile-wide moon Rhea doesn't look like this in normal light. The image is cast in false color (for scientific reasons, of course) using images taken in several different wavelengths.

Scientists aren't certain what to make of the stripes that appear in the composite image, but they do think Rhea is about one part rock and three parts ice. Like Dione, it also seems to have huge cliffs of ice.
