Remember that image from a few weeks back that showed Earth with all its water gathered up in a sphere beside it? Well here’s that image again, only this time, it also features Jupiter’s moon Europa, along with all of its water.
Based on data acquired by NASA’s Galileo satellite, astronomers think the global oceans sloshing around beneath Europa’s icy exterior are likely 2—3 times more voluminous than the oceans here on Earth. Not 2—3 times more proportionally, 2—3 times more in total volume.
Look here for more scientific input.
