Caption: A false-color image of Saturn's rings.

This image is based on visible light and ultraviolet light.

The A ring (the outermost broad band shown in brown mostly), the Cassini division (the 2nd region inward in dark blue mostly), the B ring (the 3rd broad region going inward in green and red), and the C ring (the 4th broad region going inward in blue mostly) can be identified.

There are finer features that can be identified too.

The Cassini division is NOT a pure gap: there are particles of scale size perhaps 10 microns in the division. They are probably rocky dust (HI-209, SRJ-227).

Chemical and physical variations in the rings---which we won't discuss here---are brought out by image enhancement techniques and are distinguished by the false colors in the image.

As one can see Saturn's rings are NOT simple when looked at closely---but this shouldn't have been a surprise.
