After years of debate, NASA researchers have zeroed in on the thickness of the Europa's ice shell. We first discovered that the Jupiter moon's surface looked icy in 1979, when Voyager 2 flew by.

New research shows that some frozen moons may hide boiling oceans beneath their icy shells, shaping strange surface features.

Data from NASA's Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter's moon Europa. Using the spacecraft's Microwave Radiometer (MWR), ...
