The thin silver of Saturn’s moon Prometheus lurks near ghostly structures in Saturn’s narrow F ring in this view from our Cassini spacecraft. Many of the narrow ring’s faint and wispy features result from its gravitational interactions with Prometheus.
Most of the small moon’s surface is in darkness due to the viewing geometry here. Cassini was positioned behind Saturn and Prometheus with respect to the Sun, looking toward the moon’s dark side and just a bit of the moon’s sunlit northern hemisphere.
