Ringshine

The spacecraft photographed the planet's sunlit crescent, the ring shadows falling on the planet, and Saturn's dark hemisphere illuminated by "ringshine."

One, the ``dragon storm, is shown in Figure 5.28 (see color section), while another example, on Saturn's night side, but illuminated by ``ringshine (i.e., light reflected from Saturn's rings) is shown in Figure 5.29.

Elephant juddered briefly, making the insertion burn, and then they were racing around the dark side of Saturn, faintly illuminated by the ghost light of ringshine.
