Exobiology, Titan

Scientific paper

Titan, the largest satellite of Saturn, is currently the most favorable site for search of extraterrestrial life. This moon is one of the solar system bodies, which could have a large quantity of liquid water. The putative internal ocean along with a rich dense atmosphere provide some new exobiological niches: (1) the upper layer of the internal water ocean; (2) water pockets and liquid veins inside icy layer; (3) the places of cryogenic volcanism; (4) set of caves in icy layer connecting with cryovolcanic processes; (5) the brinefilled cracks in icy crust caused by tidal forces; (6) liquid water pools on the surface originated from meteoritic strikes; (7) the sites of hydrothermal activity on the bottom of ocean. All conditions needed for exobiology - liquid water, complex organic chemistry and energy sources for support of biological processes - are on Saturnian moon.
