Imagine a shift in the position of Earth’s continents so extreme
would move to the equator. Astronomers have now found evidence that such a shift
actually happened on Jupiter’s large icy moon Europa. The sliding of the moon’s
icy surface provides further evidence that an ocean lies beneath the ice,
upping the odds that Europa has a subterranean habitat that could support some
kind of life.
