  This Cassini view shows details of Saturn's outer A ring, including the Encke and Keeler gaps. The A ring brightens substantially outside the Keeler Gap.

On both sides of the broad Encke gap are bright spiral density waves.

This view looks toward the lit side of the rings from about 52 degrees below the ringplane.

The image was taken with the Cassini spacecraft narrow-angle camera using a spectral filter sensitive to wavelengths of infrared light centered at 930 nanometers. The view was acquired on Feb. 19, 2007 at a distance of approximately 950,000 kilometers (590,000 miles) from Saturn. Image scale is 5 kilometers (3 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.
