    Titan, the Saturn's biggest moon, is the subject of many studies because it is an active world, both geologically and chemically. The chemistry in the atmosphere and on the surface of Titan seems to be particularly complex and it may inform us on the carbon molecules' evolution process, some of which could be a basis for life as we know it on Earth. This chemistry, triggered in the Titan's upper atmosphere, gave birth to a set of chemical reactions which have been producing increasingly complex carbon molecules (hydrocarbons, nitriles, etc.), even solid particles, aerosols, which form the orange fog and give its distinctive colour to Titan.
