Cosmic "Through-and-Through"!

Caption NASA:"Prometheus pulls away from an encounter with Saturn's F-Ring, leaving behind a reminder of its passage.
Prometheus (about 102 Km, or 63 miles across) approaches closely to the F-Ring once during each circuit around Saturn, disturbing the orbits of the small particles in the Ring and creating a streamer of material that then shears out, following the moon as it speeds off.
This view looks toward the unilluminated side of the Rings from about 37° above the Ring-Plane. Prometheus is brightly lit by the Sun on one side and lit more modestly by Saturn's reflected light on the other side.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 18, 2007 at a distance of approx. 2 MKM (about 1,2 MMs) from Prometheus and at a Sun-Prometheus-spacecraft, or phase angle of 87°. Image scale is roughly 12 Km (about 7 miles) per pixel".
