The Earth and Titan, largest satellite of Saturn are often compared by their atmospheric similarities: both have a dense atmosphere mainly made of nitrogen, with a pressure of the order of magnitude of a bar at the surface. However their composition significantly differs because of the second mostly abundant constituent: oxygen on Earth and methane on Titan. Terrestrial atmosphere is therefore oxidizing whereas Titanian atmosphere is reducing. This major difference leads to radically different chemistry patterns for organic species: oxidation lyses organic skeletons whereas photochemistry in reducing conditions leads to an efficient growth of the carbon chains. A reducing atmospheric chemistry therefore produces complex structures and a wid...
