This moon has twice Earth's water. None of it has ever seen the sun.

Europa's ocean is 100 km deep. Earth's deepest trench is 11. Buried under 15 miles of ice, heated by Jupiter's gravity kneading the moon like dough, it may have hosted hydrothermal vents for billions of years, the same kind of vents where we found life on Earth thriving without sunlight. In 2017, Hubble caught water geysering 200 km into space from Europa's surface. NASA built a spacecraft the size of a basketball court to fly through it 49 times and taste what comes out.
