Q:

What color are Jupiter's rings?

A:

Jupiter's gossamer and main rings are red, whereas the inner halo ring is bluish. Scientists determine the color of the rings of Jupiter by examining the wavelengths of the particles making up the rings, and the way light scatters from them.

The rings are formed out of material from some of Jupiter's moons. The innermost ring, called the halo ring, differs in color from the other two sets of rings due to its unique shape, created by its closeness to Jupiter's powerful electromagnetic field. The differing shape changes the ring's spectral properties, making it blue even though it is composed of the same materials as the other ring sets.

    Why are Saturn's rings so noticeable?

    A:

    Scientists speculate that the rings around Saturn are bright because they are young and haven't had time to collect space dust. Space dust would dull the rings around Saturn in much the same way dust dulls the surface of objects on Earth.
