Charon, Pluto's sole moon has been discovered to have volcanoes that spew water ice into space. Water apparently is liquid inside the moon, probably due to an ammonia mixture that acts like an antifreeze. The water instantly turns to ice when they hit the cold of space. The volcanoes were detected with the Gemini observatory on Mauna Kea in Hawaii. The picture above is an artist's rendition.
