  This spectacular and disorienting maze of lines is a Cassini portrait of the gas giant Saturn, its rings and its small, icy moon Mimas. The rings cast dark shadows across Saturnís northern hemisphere, creating a photonegative effect: dark sections are dense and block the sun, while bright sections are less dense areas or gaps in the rings which are more transparent to sunlight.

Mimas (396 kilometers, 246 miles across) is seen here against the backdrop created by the shadow of the dense B ring. Above Mimas and the B ring shadow can be seen the broad gap of the Cassini Division. The actual Cassini Division, which divides the A and B rings, is visible about one-third of the way up from the bottom of the image.

This image was taken from beneath the plane of Saturnís rings. It is similar to the serene portrait provided by Cassini in a natural color view from November, 2004 (see PIA06142).

This view was obtained in visible light with the narrow angle camera on October 15, 2004, from a distance of approximately 4.7 million kilometers (2.9 million miles) from Saturn. The image scale is 28 kilometers (17 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.
