Tethys passes silently between Saturn and Cassini as a train of storms rumbles through the planet's southern hemisphere. The rings' shadows darken the planet at top.
Tethys is 1,062 kilometers (660 miles) across.
This view looks toward the unilluminated side of the rings from about 2 degrees above the ringplane.
The image was taken in visible red light with the Cassini spacecraft wide-angle camera on June 4, 2008. The view was acquired at a distance of approximately 1.2 million kilometers (756,000 miles) from Saturn. Image scale is 69 kilometers (43 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.
