  Saturn's magnificent rings show some of their intricate structure in this narrow angle camera image from May 11, 2004. Although they appear to be solid structures, the rings are composed of billions of individual particles, each one orbiting the planet on its own path.

Satellites visible in this image: Janus (179 kilometers, 111 miles across) above the rings, and icy Enceladus (504 kilometers, 313 miles across) below the rings. The F ring shepherd moons Prometheus and Pandora can be seen along Saturn's outermost F ring if the image is further contrast enhanced. The image was taken in visible light from a distance of 26.3 million kilometers (16.4 million miles) from Saturn. The image scale is 158 kilometers (98 miles) per pixel. Contrast in the image was enhanced 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.
