Turbulences

Caption NASA:"The Cassini Spacecraft has a peek beneath the hazes in Saturn's Upper Atmosphere at the swirling vortices that lurk below.
Many vortices can be seen in this image, varying in size from small to large.
The largest one in this image exhibits a collar of bright clouds surrounding the central dark core.
The view is centered on a region about 46° South of the Planet's Equator.

The image was taken with the Cassini spacecraft narrow-angle camera on Aug. 12, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 750 nanometers. The view was acquired at a distance of approx. 4,1 MKM (such as about 2,5 MMs) from Saturn.
Image scale is roughly 24 Km (about 15 miles) per pixel".
