  Shadows cast by Saturn's rings separate the planet's bright equatorial band from the darker northern latitudes.

This view makes use of a spectral filter sensitive to absorption of certain wavelengths of light by methane in Saturn's atmosphere. In the north, the light at these wavelengths reaches slightly greater depth before being reflected off the cloud tops, compared to the equatorial region--and it passes through more light-absorbing methane along the way.

The innermost rings arc across the lower left corner. The view looks toward the unilluminated side of the rings from about 37 degrees above the ringplane.

The image was taken with the Cassini spacecraft wide-angle camera on Feb. 18, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 890 nanometers.

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.
