Pan's Slender Shadow
[For trouble viewing the images/movies on this page, go here]
Saturn's moon Pan casts a delicate shadow onto the planet's A ring.

Shown in the center of this image, Pan (28 kilometers, 17 miles across) orbits within the Encke Gap of the A ring. Other bright specks in the image are background stars. As Saturn approaches its August 2009 equinox, the planet's moons cast shadows onto the rings. To learn more about this special time and to see a movie of a moon's shadow moving across the rings, see PIA11651.

This view looks toward the unilluminated side of the rings from about 51 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 2, 2009. The view was acquired at a distance of approximately 1.4 million kilometers (870,000 miles) from Pan and at a Sun-Pan-spacecraft, or phase, angle of 108 degrees. Image scale is 9 kilometers (5 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.
