  •  Could the shadow be a filter on the camera? (0+ / 0-)

    When I first saw the picture, I found it disorienting until I realized that the black shadow could be blocking the sunlight.  The sun is behind the planet - an angle which the Cassini does not often get with the rings tilted - which is why the picture was taken.

      The black part is a shadow, due to the angle between the Sun-Saturn line and the Saturn-Cassini line. Then we see Saturn by reflected light from the rings onto Saturn's cloud tops and back out.

      This is a false color image, combining infrared and visible light images taken through three filters.

      This is explained at Astronomy Picture of the Day today.
