Saturn, Janus and Mimas (in natural colors)

Caption NASA originale:"Looking something like the fibrous bow of a violin, Saturn's colorful rings sweep through this spectacular natural color view while two small moons look on.
From left, the moons visible here are Janus (181 Km across) and Mimas (398 Km across). Cassini's view in this image is from beneath the ring plane; the moons are on the far side of Saturn. Janus leads Mimas as the two moons orbit the planet. Nearly the entire ring system can be seen in this view. The diaphanous C-Ring appears at the upper right, followed by the multi-hued B-Ring. Next, the famous Cassini division (4.800 Km wide) separates the A and B rings. The outer edge of the B-Ring which forms the inner boundary of the Cassini division is maintained by a gravitational resonance with Mimas. Near the outer edge of the A-Ring are the Encke Gap (325 Km wide) and the barely visible Keeler Gap (35 Km wide). The faint, thread-like F-Ring is slightly discernible just beyond the main rings".
