Saturn's A Ring in False Colour

An Artifical Image of the Outer Part of Saturn's A Ring Shown in False Colour

The image was generated from the Voyager PPS occultation data. It was used in image compression studies for the Cassini Imaging Science Subsystem cameras. The prominent gap running from bottom left to top right is the 325-km wide Encke Gap. The narrower gap near the edge of the A ring is the 30-km wide Keeler Gap. Note the detailed radial structure in the ring. This is caused by resonances with small satellites orbiting just beyond the rings. The F ring is just visible in the bottom right-hand corner.
