Enceladus: water world
This view of Saturn’s moon Enceladus above the planet’s ring plane was captured by the narrow-angle camera of NASA’s Cassini spacecraft at a distance of approximately 630,000 miles (1 million kilometres) from the tiny water world. Enceladus is subject to forces that heat a global ocean of liquid water under its icy surface, resulting in its famous south polar water jets which are just visible below the moon’s dark, southern limb.
