Saturn's C and B Rings From the Inside Out.
Images taken during the Cassini spacecraft's orbital insertion on June 30 show definite compositional variation within the rings.
This image shows, from left to right, the outer portion of the C ring and inner portion of the B ring. The B ring begins a little more than halfway across the image. The general pattern is from "dirty" particles indicated by red to cleaner ice particles shown in turquoise in the outer parts of the rings.
The ring system begins from the inside out with the D, C, B and A rings followed by the F, G and E rings.
This image was taken with the Ultraviolet Imaging Spectrograph instrument, which is capable of resolving the rings to show features up to 97 kilometers (60 miles) across, roughly 100 times the resolution of ultraviolet data obtained by the Voyager 2 spacecraft.
