  Saturn’s shadow sweeps across the rings in a view captured on Nov. 5, 2006 by NASA’s Cassini spacecraft. In the bottom half of the image, the countless icy particles that make up the rings bask in full daylight. In the top half, they move through Saturn’s shadow. On the right side of the image, the planet’s night side, dimly lit by reflected ringshine, can be seen through gaps in the darkened rings.

This view is a mosaic of four visible light images taken with Cassini's narrow-angle camera at a distance of approximately 932,000 miles (1.5 million kilometers) from Saturn.

The Cassini spacecraft ended its mission on Sept. 15, 2017.

The Cassini Solstice 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.
