That's no moon... oh wait, yes it is. It's Saturn's moon Mimas and it's large Herschel Crater. Shadows cast across the moon, provide an indication of the size of the crater's towering walls and central peak.

Named after the icy moon's discoverer, astronomer William Herschel, the crater stretches 86 miles (139 kilometers) wide -- almost one-third of the diameter of Mimas (246 miles or 396 kilometers) itself. Large impact craters often have peaks in their center. Herschel's peak stands nearly as tall as Mount Everest on Earth.
