In, Through, and Beyond Saturn's Rings
This image of Saturn's rings features four of its moons. The largest, Titan, is in the background with its north polar hood visible through its perpetual clouds. Bright Dione is in the foreground, showing craters and ice cliffs. Saturn's expansive A ring juts in from the left, a striking boundary in this cosmic scene.
