Dark Shadows

ring_shadows

A sliver of a shadow, thousands of miles long, slices into the twilight side of Saturn’s rings and drifts off the edge of the A ring in this 8-frame animation. (Click the image to play.)

As well as the motion of the moon shadow, thicker sections of the F ring can be seen moving along their path.

Made from raw images from the Cassini orbiter received on Earth on June 17, 2009.
