CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Sliding Shadows

Dark ring shadows adorn the northern hemisphere of Saturn. The shadows have loosened their grip on the north compared to when Cassini arrived in 2004 (see PIA06177), and presently continue to slide farther south.

This view looks toward the unilluminated side of the rings from about 5 degrees above the ringplane.

Images taken using red, green and blue spectral filters were combined to create this natural color view. The view was acquired with the Cassini spacecraft wide-angle camera on Oct. 22, 2007, at a distance of approximately 1.3 million kilometers (839,000 miles) from Saturn. Image scale is 77 kilometers (48 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.

Now I am shure. Just like in the city I live in, the shawdows must have
some effect on what climate occurse below it. Wonder just what the thermo
reads are from the shadows cast in the atmostphere by Saturn's rings?

Well? Huh? Anybody? Spectrograph.. please! The color in visble light
is of course wonerful to see as well.
