'Ice volcano' found on Saturn's moon

Summary

17 December 2010

Saturn’s largest moon, Titan, is made up mainly of water, ice and mountains. Now scientists think they’ve found a mountain that spews lava1 made not of molten rock, but ice. The observation was announced at the American Geophysical Union meeting in San Francisco. Jonathan Amos reports.

Report

Titan is a mysterious world. Because it's shrouded2 in a thick, oily haze3, it's extremely hard to identify anything at the moon with confidence. But with temperatures that plunge4 to minus 180 Celsius5 at the surface, researchers had suspected it might have ice volcanoes. 

And now the Cassini probe has spotted6 a 1,500m-high mountain with a deep pit in it, and what looks like a flow of material nearby. 

Scientists can only speculate what sort of material a cryo-volcano might erupt, but the complex chemistry at Titan suggests it could be a slushy water-ice containing ammonia.

If there are a lot of carbon molecules7 present, the lava could even look like softened8 asphalt, candle wax or even polyethylene. 

The team which discovered the mountain have dubbed9 it "the Rose".
