Islands in the stream? Possible 'islands' on a dark plain Image: ESA
23 January 2005 Last week, the European Space Agency's's Huygens probe made an historic first ever descent to the surface of Titan, the largest of Saturn's moons, some1.2 billion kilometres from Earth. Data coming from the probe shows the physical processes shaping Titan are much the same as those shaping Earth - precipitation, erosion, mechanical abrasion and other fluvial activity. The images being processed and interpreted by scientists around the world from the Huygens data are astounding. The rivers in this image are not water - they are METHANE! If you fancy a quick trip to Titan, check out these videos.
