Where this comes from

Abstract

Titan, Saturn’s largest moon, possesses a dense N<sub>2</sub>–CH<sub>4</sub> atmosphere driving complex organic chemistry. The interplay among photochemistry, aerosol formation, organic cloud condensation, and surface deposition makes Titan a natural laboratory for studying organic reaction networks and assessing the environmental conditions relevant to habitability on a cold, molecularly rich world.
