NASA recently published an exquisite Cassini spacecraft image showing Saturn's F ring, shining in scattered sunlight, and Saturn's second largest moon Rhea (1,528 km across).
The spacecraft was looking down on the dark side of the ring from just less than a degree above the ringplane. Rhea is the slender, pale crescent, loaming in the background of the ring.
The image was taken in visible light with the Cassini spacecraft wide-angle camera on 20 July 2007. Cassini was approximately 915,000 km from Rhea. Image scale is 5 km per pixel.
