The Rings over Saturn's Terminator

Caption NASA originale:"With Saturn's Terminator as a backdrop, this view of the unlit face of the Rings makes it easy to distinguish between areas that are actual gaps, where light passes through essentially unimpeded, and areas where the Rings block or scatter light. The gaps are regions in which the brightness varies strongly from left to right as the background goes from bright to dark.
Parts of the image are saturated at left.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on July 24, 2006 at a distance of approx. 577.000 Km (such as about 359.000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 101°. Image scale is roughly 31 Km (about 19 miles) per pixel".
