Dark Boundary

June 9, 2008

Saturn's semitransparent rings arc smoothly around the gas giant, abruptly disappearing where they pass through the planet's shadow.

This view looks toward the unilluminated side of the rings from about 18 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on April 15, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 728 nanometers. The view was obtained at a distance of approximately 1.5 million kilometers (907,000 miles) from Saturn. Image scale is 84 kilometers (52 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 mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
