An article published in the journal “The American Astronomical Society” reports a study on the hydrocarbon lakes existing on Titan, the great moon of Saturn, showing its similarities with the Earth’s lakes. A team of researchers led by Jordan Steckloff analyzed data collected by the Cassini space probe and discovered that the lakes of Titan composed of methane, ethane, and nitrogen form layers similar to the ones on Earth. The stratification mechanisms are different because on Earth layers are the consequence of temperature while on Titan they exist because of the particular chemical interactions between the surface liquids and the atmosphere.
