Cassini captured this revealing view, which shows that Saturn's hydrogen- and helium-rich atmosphere is a dynamic place, filled with spots, ovals and swirling vortices and filaments of gas.

The image was taken with the Cassini spacecraft wide angle camera on Dec. 14, 2004, at a distance of 595,000 kilometers (370,000 miles) from Saturn through a filter sensitive to wavelengths of infrared light centered at 939 nanometers. It has been highly processed to enhance details. The image scale is about 32 kilometers (20 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 team is based at the Space Science Institute, Boulder, Colo.
