Titan Tholins: Simulating Titan Organic Chemistry in the Cassini-Huygens Era.

The article focuses on the organic chemical composition of Titan based on the discovery report of the Cassini-Huygens mission to the Saturn system. It mentions that Titan's atmosphere was denser than the Earth's and consists of nitrogen, carbon monoxide, methane, and hydrogen, and the surface have various putative energy sources. Furthermore, information on Tholin, which is a sticky brownish residue formed in Titan atmospheric simulation experiments, is presented.
