Researchers explain the presence of hydrocarbons on extraterrestrial bodies like Titan through a combination of factors. Titan's atmosphere is rich in methane, which plays a central role in maintaining its thick nitrogen atmosphere and is the source of hydrocarbon hazes. These hazes absorb sunlight and help regulate the planet's temperature. The hydrocarbons are also believed to originate from the upper atmosphere, where complex organic chemistry occurs. This chemistry is influenced by cosmic rays and ultraviolet light, which break down methane and other simple molecules into more complex organic compounds.

A global sedimentary cycle driven by seasons could explain the formation of landscapes on Titan, which are rich in hydrocarbons. Some of these heavy, carbon-rich compounds settle to the moon's surface, playing the role of "sand" in vast dune fields. Additionally, the presence of hydrocarbons on Titan suggests that they can be naturally produced by inorganic means, indicating that hydrocarbons are not solely a product of biological processes.

The research also indicates that Titan has seas and rains of liquid methane, which contribute to its hydrocarbon-rich environment. The hydrocarbon chemistry in Titan's atmosphere showcases unique cloud and haze formation mechanisms, different from those on Earth.
