'Ice volcano' found on Saturn's moon

Saturn's largest moon, Titan, is made up mainly of water, ice and mountains. Now scientists think they've found a mountain that spews lava made not of molten rock, but ice. The observation was announced at the American Geophysical Union meeting in San Francisco.Titan is a mysterious world. Because it is shrouded in a thick, oily haze, it is extremely hard to identify anything at the moon with confidence. But with temperatures that plunge to minus 180 Celsius at the surface, researchers had suspected it might have ice volcanoes.

And now the Cassini probe has spotted 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 molecules present, the lava could even look like softened asphalt, candle wax or even polyethylene.

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

Jonathan Amos, BBC News
