Lonely Moon

An astounding photo from Cassini spacecraft that captures Saturn's moon Enceladus as some 98 geyser located near its south pole eject massive amounts of water vapor and crystals into the empty dark.

Enceladus is covered in ice and it is suspected that pressure from within forces water up through cracks in the ice, forcing it to jet out at tremendous speeds for great distances. The water vapor has salt in it, about the same amount as our own earth oceans. Much of the water falls back to the moon as snow and ice.
