Study Finds Ocean Currents May Affect Rotation of Europa’s Icy Crust

NASA scientists have strong evidence that Jupiter’s moon Europa has an internal ocean under its icy outer shell – an enormous body of salty water swirling around the moon’s rocky interior. New computer modeling suggests the water may actually be pushing the ice shell along, possibly speeding up and slowing down the rotation of the moon’s icy shell over time. Scientists have known that…
