NASA has released this beautiful image of the Saturn rings, looking straight down — the outer portion of the C ring and the inner portion of the B ring. According to NASA, "the general pattern is from "dirty" particles indicated by red to cleaner ice particles shown in turquoise in the outer parts of the rings."
This image was taken by its 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.
Here are the rings in natural colour. Zoom in to see all the parts in detail.
