Background:土卫六是土星最大的卫星，它主要是由水、冰和山脉组成。科学家近日在旧金山召开的美国地球物理学联合会上宣称他们可能在土卫六上发现了冰火山。

Titan shroudedis a mysterious world. Because it's shrouded in a thick, oily haze, it's 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.

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".
