Caption NASA:"A great vortex, ringed by bright clouds, rolls through the Southern Skies of Saturn in this Cassini spacecraft view.
The image was taken using a spectral filter sensitive to wavelengths of infrared light centered at 750 nanometers. The view was obtained with the Cassini spacecraft narrow-angle camera on July 11, 2007 at a distance of approx. 2,8 MKM (such as about 1,8 MMs) from Saturn.
Image scale is roughly 17 Km (about 10 miles) per pixel".
