Rough Around the Edges

July 21, 2008

This detailed look at Saturn's A ring captures Daphnis in the narrow Keeler Gap. The small moon creates complex wave patterns in the gap edges that Cassini scientists are working to understand.

To the right of the Keeler Gap, the outer A-ring edge is significantly brighter than the rest of the ring.

This view looks toward the unilluminated side of the rings from about 32 degrees above the ringplane. Daphnis is 8 kilometers (5 miles) wide.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 31, 2008. The view was acquired at a distance of approximately 1 million kilometers (629,000 miles) from Saturn. Image scale is 6 kilometers (4 miles) per pixel.
