Explanation: What do Saturn's rings look like from the other side?
From Earth, we usually see Saturn's rings from the same side of the ring plane that the Sun illuminates them.
Geometrically, in the above picture taken in April by the robot Cassini spacecraft now orbiting Saturn, the Sun is behind the camera but on the other side of the ring plane.
The unexpected shadowy regions once recorded by the Voyager missions when they passed Saturn in the early 1980s are not, so far, being seen by Cassini.
