Tethys and the South Pole of Saturn

Caption NASA originale:"This dazzling view looks beyond gigantic storms near Saturn's South Pole to the small but clear disc of Tethys (1.060 Km across). Clouds and ribbons of gas swirl about in the planet's atmosphere in the foreground, while a tremendous chasm is visible on the icy moon. The image was taken with the Cassini spacecraft narrow angle camera on Oct. 18, 2004, at a distance of about 3.9 MKMs from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 61°. The view is in wavelengths of visible red light centered at 619 nanometers. The image scale is 23 Km per pixel".
