  Looking something like the fibrous bow of a violin, Saturnís colorful rings sweep through this spectacular natural color view while two small moons look on.

From left, the moons visible here are Janus (179 kilometers, 111 miles across) and Mimas (396 kilometers, 246 miles across). Cassiniís view in this image is from beneath the ring plane; the moons are on the far side of Saturn. Janus leads Mimas as the two moons orbit the planet.

Nearly the entire ring system is can be seen in this view. The diaphanous C ring appears at upper right, followed by the multi-hued B ring. Next, the famous Cassini division (4,800 kilometers, 2,980 miles wide) separates the A and B rings. The outer edge of the B ring which forms the inner boundary of the Cassini division is maintained by a gravitational resonance with Mimas. Near the outer edge of the A ring are the Encke Gap (325 kilometers, 202 miles wide) and the barely visible Keeler Gap (42 kilometers, 26 miles wide). The faint, thread-like F ring is discernible just beyond the main rings.

The image was obtained with the narrow angle camera on August 27, 2004, from a distance of 9.1 million kilometers (5.6 million miles) from Saturn. Images taken with red, green and blue filters were combined to create this color view. The moons have been enhanced in brightnesses to increase their visibility. The image scale is 54 kilometers (34 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.
