"Saturn’s moon Enceladus has a cold geyser, which spouts as much water and gas as Old Faithful in Yellowstone National Park. Enceladus' plume is largely powered by carbon dioxide gas, but also contains methane, nitrogen and propane. Since Enceladus' gravity is 86 times smaller than Earth's, this spout streams thousands of kilometres into space and is probably the source of the particles in Saturn's E ring. The Cassini team suggest that it could supply at least 150 kilograms of material to the ring every second."

from the Nature article I tried to post links to the other day that didn't work.
