  The dark Cassini Division contains a great deal of structure, as seen in this Cassini color image. The sharp inner boundary of the division (left of center) is the outer edge of the massive B ring and is maintained by the gravitational influence of the moon Mimas.

Spectroscopic observations by Cassini indicate that the Cassini Division, spectroscopically similar to the C ring, contains more contaminated ice than do the B and A rings on either side.

This view is centered on a region approximately 118,500 kilometers (73,600 miles) from Saturn's center. (Saturn is 120,500 kilometers, or 74,900 miles, wide at its equator.) From left to right, the image spans approximately 11,000 kilometers (6,800 miles) across the ringplane.

A closer view of the outer edge of the Cassini Division can be seen in PIA07616.

Images taken using red, green and blue spectral filters were combined to create this view, which approximates what the human eye might see. The image was taken with the Cassini narrow-angle camera on May 18, 2005, at a distance of approximately 1.6 million kilometers (1 million miles) from Saturn. The image scale is 9 kilometers (6 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
