Hi, I'm new. I'm currently studying A-levels, and I'm going to study astrophysics at uni, so I may be on this website quite often asking questions in the future! Secondly, I have a question. Why is there LIQUID water under Enceladus' surface? Is it similar to Europa around Jupiter where there are frictional forces involved? Also, what does everyone here make of the chances of there being life under the surface of Enceladus? And how evolved it would be?
