From the NASA web site: An ice geyser projects a jet of vapor into the vacuum of space from the surface of Enceladus, a small moon orbiting the gas giant Saturn. Ice geysers like this one hint that a giant ocean rumbles beneath the icy surface of Enceladus—and in that ocean, the possibility of extraterrestrial life.
