NASA's Galileo spacecraft has found evidence of water beneath the icy surface of Jupiter's moon Europa, researchers said.
The data suggest there is significant exchange between Europa's icy shell and the ocean beneath.
NASA's Galileo spacecraft has found evidence of water beneath the icy surface of Jupiter's moon Europa, researchers said.
The data suggest there is significant exchange between Europa's icy shell and the ocean beneath.
Europa's ice shell is about 10 km thick and within it are giant pockets of water, lying at depths as shallow as three kilometers. Warm water from these sub-surface lakes wells up in plumes, causing the ice to become brittle, crack and collapse.
