An interesting curl in the boundary of a dark polar collar, an area where the bright and dark regions of the atmosphere meet, is visible in this view of Saturn's southern polar region.

The image was taken with the Cassini spacecraft narrow angle camera on July 21, 2004, from a distance of 6.4 million kilometers (4 million miles) from Saturn, through a filter sensitive to wavelengths of infrared light. The image scale is 38 kilometers (24 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 Office of Space Science, 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.
