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 NASA/ESA/ASI Cassini-Huygens narrow-angle camera on 21 July 2004, from a distance of 6.4 million kilometres from Saturn, through a filter sensitive to wavelengths of infrared light. The image scale is 38 kilometres per pixel. Contrast was slightly enhanced to bring out features in the atmosphere.
