  Cassini looks past the night side of Saturn, dimly lit on the left of this image by ringshine, for a subtly distorted view of the planet's rings.

Light passing through the upper reaches of the planet's atmosphere is refracted, or bent, distorting the view of the rings beyond. See PIA07521 to learn more.

Bright specks in the image are background stars. This view looks toward the sunlit, northern side of the rings from about 9 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 7, 2009. The view was acquired at a distance of approximately 3 million kilometers (1.9 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 102 degrees. Image scale is 17 kilometers (11 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. 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.

Very interesting, like another similar images, but this time with the bonus of Saturn's night side. Keep them coming.
