This narrow angle ultraviolet image probes the high atmosphere above Saturn's south pole. A bright wedge near the lower-left limb falls in a latitude band which borders a darker latitude band a little closer to the pole. Viewing the limb of the planet in ultraviolet light allows researchers to sample the high part of the atmosphere (the stratosphere). Scientists can discern from this image that the stratosphere in this latitude band is relatively pure hydrogen and helium and contains very little of the stratospheric haze which causes darkening closer to the pole. The image was taken by the Cassini spacecraft on July 26, 2004, at a distance of 7.1 million kilometers (4.4 million miles) from Saturn. The image scale is 42 kilometers (26 miles) per pixel. Contrast was slightly enhanced to bring out features in the atmosphere. 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 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.
