The effects of the small moon Prometheus loom large on two of Saturn's rings in this image released by NASA.

The gravity of Prometheus periodically creates streamer-channels in the F ring.The image was taken in visible light with the Cassini spacecraft narrow-angle camera.

The view was acquired at a distance of approximately 1.8 million kilometres (1.1 million miles) from Saturn
