Saturn and the shadow of his Rings

This majestic view of Saturn captures several phenomena of interest to scientists working on the Cassini mission. The planet's nighttime atmosphere looms ahead - an excellent place to search for storms and lightning. Saturn's shadow stretches across the rings, which will over the next four years receive their most thorough examination since Galileo discovered them in 1610. And barely visible near lower right just inside the F-Ring, is the small shepherd moon Prometheus (102 Km across). Researchers will explore the many moons of Saturn, including special ones like Prometheus that help maintain some of the rings and gaps in this complex and dynamic system.
The image was taken in visible light with the Cassini spacecraft wide angle camera on Oct. 29, 2004, at a distance of about 940.000 Km from Saturn. The image scale is 52 Km per pixel."
