Outer B Ring Edge December 3, 2004	Full-Res: PIA06535
This close-up of the lit side of Saturn's outer B ring and the Cassini Division looks something like a phonograph record. There are subtle, wavelike patterns, hundreds of narrow features resembling a record's 'grooves' and a noticeable abrupt change in overall brightness beyond the dark gap near the right. To the left of the gap is the outer B ring with its sharp edge maintained by a strong gravitational resonance with the moon Mimas. To the right of the Huygens Gap are the plateau-like bands of the Cassini Division. The narrow ringlet within the gap is called the Huygens ringlet.

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 Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
