Sunlight reflects off the bright, frozen surfaces of the billions and billions of ring particles comprising Saturn's rings to brighten the planet's southern skies.
The particles in Saturn's rings are each too small to be seen by Cassini in this image. If they could, each would look like the bright reflective crescent of Enceladus (504 kilometers, 313 miles across) seen here, with each reflecting sunlight onto the southern hemisphere of the planet.
The image was taken in polarized infrared light with the Cassini spacecraft wide-angle camera on Nov. 2, 2005, at a distance of approximately 1.7 million kilometers (1.1 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 119 degrees. The image scale is 104 kilometers (65 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.
