Snowball Fight In Saturn Ring

http://www.bbc.co.uk/news/science-environment-17822755

Small clumps of ice have been seen passing through Saturn's F-ring, that is its outermost ring, and leaving small trails behind them, which causes shapes that resemble the barbs on a harpoon to be traced on the ring.This phenomena is caused by one of Saturn's moons, Prometheus, travelling extremely close to the ring and disturbing the ice particles within it which causes them to clump together to form these snowballs. Also, Prometheus is known to be capable of producing concentrations of materials in the ring so some of these snowballs may be a result of these materials as well. More research will be put into these snowballs as scientists are very interested in obtaining information regarding the rings of Saturn. This interest comes from the fact that these rings can assist us in gaining insight into the processes that ocurred in the early history of all planetary systems. As I see it, any information we can gain in regards to the development of our universe will be beneficial in advancing many areas of science, specifically physics.
