Science The Other Volcano
Posted by Charles Mudede on Wed, Dec 17, 2008 at 11:13 AM
Titan, the haze-shrouded moon of Saturn, displays tantalising evidence of ice volcanoes.Two regions of Titan have been seen recently, by the Cassini spacecraft, to undergo clear changes in brightness.
This activity, and radar images hinting at flow-like structures, suggest the presence of volcanoes, scientists say.
Rather than erupting molten rock, Titan's "cryovolcanoes" are thought to ooze a slurry made of water ice, ammonia and methane.
There are suggestions that these frigid lava flows could be as much as 200m thick.
Considering what's happening in the arctic, our poor planet could use an ice volcano or two.
