CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Rings and Waves

Saturn's A ring is decorated with several kinds of waves. Here Cassini has captured a host of density waves, a bending wave (in the upper-right corner), and the edge waves on the edge of the Keeler gap caused by the small moon Daphnis. Daphnis itself appears as a tiny dot in the middle of the Keeler gap.

See PIA10501 for a closer look at bending and density waves and to learn more about them. For more on the edge waves caused by Daphnis, see PIA11655.

This view looks toward the unilluminated side of the rings from about 41 degrees below the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 28, 2013.

The view was obtained at a distance of approximately 777,000 miles (1.3 million kilometers) from Daphnis and at a Sun-Daphnis-spacecraft, or phase, angle of 76 degrees. Image scale is 5 miles (8 kilometers) per pixel.

The Cassini Solstice Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
