Possible Ice Volcano Spied on Saturn Moon

Scientists said they have found the best evidence yet of ice volcanoes on Saturn's giant moon Titan. Unlike volcanoes on Earth, such a volcano on Titan may spew ice and hydrocarbons instead of molten lava. "We finally have some proof that Titan is an active world," said geophysicist Randolph Kirk of the U.S. Geological Survey, who presented the findings.

The latest evidence comes from the international Cassini spacecraft, which spied two peaks over 3,000 feet tall and what looked like old volcanic flows. Researchers said the landforms resembled Mount Etna in Italy or Laki volcano in Iceland. There's no sign of volcanic activity on Titan, though scientists are keeping watch.
