  From on high, Cassini spots a group of faint spokes against the striped landscape of the B ring, the dark region in the middle of the rings here. The spokes appear as irregular blotches, bright against the unlit side of the rings.

Outside the rings, at about the two o'clock position in the image, is the moon Janus (179 kilometers, 111 miles across). The two points of light below center, on both sides of the F ring, are not the shepherd moons Prometheus and Pandora, but rather, are stars in the background. Other faint stars are also visible in the image.

This view looks toward the unlit side of the rings from about 46 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on Dec. 20, 2006 at a distance of approximately 1.9 million kilometers (1.2 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 144 degrees. Image scale is 109 kilometers (68 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.
