  Prometheus (86 kilometers, 53 miles across) is seen again orbiting interior to the F-ring, which exhibits some of the knotted structure for which it is renowned. Near center, separating the A and B rings is the famous Cassini division. The image was taken with the narrow angle camera on May 10, 2004 at a distance of 27 million kilometers (16.8 million miles) from Saturn. Image scale is 161 kilometers (100 miles) per pixel. The image has been contrast-enhanced and magnified to aid visibility.

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 Office of Space Science, 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.
