Enceladus
An icy moon of Saturn, Enceladus has a bright surface and large areas with few craters. This smoother terrain is young, having been resurfaced in recent geologic time. Deep cracks near the south pole, often called “tiger stripes,” are vents for huge plumes of water vapor. The plumes of Enceladus are fed by a global ocean, 6 miles (10 kilometers) beneath the moon’s icy crust. The existence of this ocean makes Enceladus an intriguing site for the search for life in our solar system.
