The Cassini probe has discovered more interesting stuff about Saturn's Moon Titan. The 3D image of the supposed "Ice Volcano" came from two separate flybys of the Cassini probe. The mountain causing all the excitement is Sotra Facula. It is a circular mountain about 40 miles (70 kilometres) across. These Ice volcanoes, or cryovolcanoes, are important for many reasons. First, they may explain the abundance of methane in Titan's atmosphere, as the volcanoes would release it into the atmosphere. This would replenish the methane lost to the sun, and keep Titan's atmosphere methane rich. Secondly, this source of methane would help fuel Titan's methane-ethane cycle, similar to the hydrologic cycle on Earth.
