Though wildly different in so many ways, Saturn’s moon Titan has something important in common with the Earth. Among all the objects in the Solar System, they’re the only two with liquids on their surfaces. Saturn’s largest moon, Titan, stands out as a dynamic, icy oceanic world featuring Earthlike hydrocarbon reservoirs that cycle through its atmosphere, surface, and interior. Titan’s atmosphere also creates complex organic molecules that could sink into the moon’s subsurface oceans and form prebiotic chemistry. (from New Thinking Allowed)
