Â© 2012 Discovery Channel. New research shows that the jumbled ice blocks crowning the surface of Jupiter's icy moon Europa are signs of large liquid lakes below, a key finding in the search for places where life might exist beyond Earth.
The Galileo mission discovered something amazing! Europa has its own atmosphere, although it is very, very thin. This atmosphere is created when fast moving molecules in Jupiter's magnetosphere hit the surface of Europa and knock out a water molecule. These molecules may float around Europa for awhile, but because of Europa's weak gravity, the atmosphere rapidly drifts away. Because Europa has an atmosphere with molecules that can escape, there is a donut-shaped belt of material inside Jupiter's magnetosphere that is called the Europa torus. Jupiter's moon Io also has a torus.
