hat you have here is a view of the giant planet Jupiter from a vantage point somewhere above the
surface of Europa, one of its icy moons. The Sun is right behind you but just below the moon's
horizon, so the light in this rendition is coming from Jupiter. Europa's surface is a cracked layer
of ice that looks like a jigsaw puzzle. The ice has been fractured because, probably, there is a
sub-Europan ocean of liquid water constantly on the move beneath it.
