An Ocean Flows Under Saturn's Icy Moon Enceladus

Saturn's moon Enceladus is an active water world with a global body of water sloshing around deep below its icy crust, scientists have confirmed. The smoking gun is the very slight wobble that Enceladus displays as it orbits Saturn. Instead, the moon must contain a complete ocean layer, according to new research that relied on more than seven years of images taken by NASA's Cassini space probe.
