Cool News About Saturn Not Involving A Crashing Space Probe

On Thursday, NASA's Cassini space probe will be passing a mere 100 miles by a cold rock named Enceladus orbiting Saturn. It will of course be taking pictures. The most interstice thing about this moon is that it might be the most likely place in our solar system, other than Earth, that has liquid water present on it's surface. It is extremely cold but due to the theory that ammonia is mixed with the water, the freezing point is greatly reduced and can thus remain in a liquid form. However, what I think is far more interesting about the whole theory is that the researchers believe that "below the moon's crust lies a vast reservoir of liquid that periodically erupts across the surface like an icy geyser or volcano." Ice volcanoes! Now that is cool!
