  Cassini peers through the icy particles that comprise Saturn's rings as Prometheus (86 kilometers, 53 miles across) sits perched on the planet's limb. The rings cast shadows on the planet, with darker regions corresponding to places where the ring material is more dense. The narrow dense regions are created by gravitational resonances with moons, like Prometheus, that orbit near the rings.

The thin, bright core of the F ring can be seen against the planet and above Prometheus.

The image was taken in visible light with the narrow angle camera on June 3, 2005, from a distance of approximately 2.1 million kilometers (1.3 million miles) from Saturn. The image scale is 13 kilometers (8 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.
