This false-color image of two density waves in Saturn's A ring was made by the Cassini-Huygens Ultraviolet Imaging Spectrograph instrument. Bright areas indicate the denser regions of the rings. Bright bands in the left part of the image are the 'peaks' of a density wave caused by gravitational stirring of the rings by Saturn's moon, Janus.

Bright areas indicate the denser regions of the rings. The bright bands in the left part of the image are the ‘peaks’ of a density wave caused by gravitational stirring of the rings by Saturn’s moon, Janus. A smaller density wave in the right half of the image is produced by the moon Pandora.Image credit: NASA/JPL/Space Science Institute
