Titan satellite of Saturn

Methane and ethane in the satellite of Saturn

A team led by Christophe Sotin of NASA’s Jet Propulsion Laboratory in Pasadena, drew  a conclusion,that there is not only methane on the Titan, but also his colleague – ethane. For a long time the scientists from the American Space Agency NASA investigated the largest natural satellite of Saturn – the Titan, who is well-known for that is the only heavenly body, except Earth, which has stable liquid on the surface. It is known, that the Titan has liquid methane lakes of the surface. Methane on a surface of the Titan plays the same role, as water on Earth. It evaporates, and then drops out in the form of a precipitation. Long-term supervision over a surface of the Titan with help of the American spacecraft Kassini satellite and its onboard scientific tools show that the lakes on a surface of the Titan gradually dry up and become the smaller size on the occupied space. But this process happens so slowly, that methane can’t be to that the reason as it evaporates quickly enough. On this basis scientists of NASA drew conclusions, that is possible as a part of lakes on the Titan is not only methane, but also his colleague – ethane. This natural gas, is similar to methane with chemical composition, evaporates and disappears much more slowly, than methane. Thus, it is possible to consider, that the American scientists made new important discovery, having logically assumed, that liquid on the largest satellite of Saturn is not only methane, but also ethane.
