I also remind you that some
chemical gunk collectively
called "tholins" was made in
Carl Sagan's lab in the 1970s. The original
goal of making this stuff was to reproduce
the observed spectrum of Titan.
The gunk? It was made out of CHON and its final
product including a bunch of organic molecules.
We now know that Titan's atmosphere includes
organic molecules like ethane (C2H6), acetylene (C2H2),
ethylene (C2H4), propane (C3H8),
hydrogen cyanide (HCN), and other more complicated
organic species.
