Huygens lands with a splat Although Huygens landed on Titan's surface on 14 January, activity at ESA's European Space Operations Centre in Darmstadt, Germany, continues at a furious pace. Scientists are still working to refine the exact location of the probe's landing site.Titan, Saturn's largest moon, is a mysterious place. Its thick atmosphere is rich in organic compounds. Some of them would be signs of life if they were on our planet. Titan is not a pleasant place for life. It is far too cold for liquid water to exist, and all known forms of life need liquid water. Titan's surface is -180°C. According to one exotic theory, long ago, the impact of a meteorite, for example, might have provided enough heat to liquify water for perhaps a few hundred or thousand years. However, it is unlikely that Titan is a site for life today.
