Sculpting the F Ring
Prometheus is caught here, in the act of pulling a new streamer out of the F ring’s inner edge. Trailing behind (above the moon in the image) are previous dark gores that Prometheus (102 kilometers, or 63 miles across) has created.
See PIA08397 for a thorough description of how the moon creates these features.
This view looks toward the unilluminated side of the rings from about 5 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 14, 2007. The view was obtained at a distance of approximately 1.7 million kilometers (1.1 million miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 67 degrees. Image scale is 10 kilometers (6 miles) per pixel.
