PIX4575163: Jupiter from its satellite Europe - Illustration - Jupiter from Europa - Illustration - Europe, Jupiter's second largest satellite, could house an ocean of liquid water beneath its icy surface. Europa, the second large moon of Jupiter, is thought to have an ocean of liquid water beneath a crust of ice. Tidal stresses from Jupiter and its neighboring moons might sometimes split open this crust, briefly exposing the liquid water to the vacuum of space, Bergeron, Joe / Bridgeman Images
