Saturn's moon Enceladus spews massive icy geysers from vents at its southern pole, as seen in images from NASA's Cassini spacecraft taken in February 2005 (top). The geysers emerge from deep fissures known as tiger stripes (bottom).

New research counters previous theories that the geysers are signs of liquid water on the distant moon.
