  Cassini captures a view showing two of Saturn's moons and their gravitational effects on nearby rings.

At top, Daphnis (8 kilometers, 5 miles across) streaks through the Keeler Gap, with its ever-present edge waves. At center, Prometheus (86 kilometers, 53 miles across) pulls away from a recent encounter with the F ring.

This view looks toward the unilluminated side of the rings from about 41 degrees above the ringplane. A bright background star is visible below the F ring.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 8, 2008. The view was acquired at a distance of approximately 1.3 million kilometers (788,000 miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 53 degrees. Image scale is 8 kilometers (5 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.
