The excellent as always Mr John Michael Godier has come out with a new video, I suggest giving it a watch. Mr Godier here explains ten mysteries of Titan, the only moon in our solar system with a substantial atmosphere, and the only other terrestrial body in our solar system with surface liquids, specifically lakes and rivers of liquid methane. It’s also becoming more and more evident that prebiotic chemistry of sorts is occurring on Titan, and what’s happening their may hold clues for the origin of life here on earth as well, as the early earth is believed to have been very similar to Titan.
It’s even possible we may find life there, however such life would be totally alien to our own, utilizing an entirely different, and also entirely hypothetical, biochemistry than the water based one that is used on earth. Titan also quite likely has a subsurface ocean of liquid water, and that subsurface ocean may very well have hydrothermal vents, meaning that it’s quite likely that even if no life is found on Titan’s surface, that life may still be found on Titan irregardless of its surface conditions.
