Saturn's B and C rings disappear behind the immense planet. Where they meet the limb, the rings appear to bend slightly owing to upper-atmospheric refraction.

Crenulations, irregularly wavy or serrated features, in the planet's clouds denote the locations of turbulent belt/zone boundaries.

The view was obtained with the Cassini spacecraft wide-angle camera on Aug. 16, 2006 at a distance of approximately 256,000 kilometers (159,000 miles) from Saturn.
