When the Sun becomes a red giant, Saturn's moon will become warm enough for life to evolve in there!

Titan, Saturn's largest moon, is a mysterious place. Its thick atmosphere is rich in organic compounds. Some of them would be signs of life if they were on our planet.

Titan's atmosphere is mostly nitrogen but there are also methane and many other organic compounds. Organic compounds form when sunlight destroys methane. If sunlight is continuously destroying methane, how is methane getting into the atmosphere?

On Earth today, it is life itself that refreshes the methane supply. Methane is a by-product of the metabolism of many organisms.

On Earth, the simplest biological sources, such as those associated with peat bogs, rice fields and ruminant animals, continuously supply fresh gas to replace that destroyed by oxidation. Could this mean there is life on Titan?

There is a theory that suggests that when our sun becomes a red giant, Saturn's moon Titan will become warm enough for life to possibly evolve in manner similar to Earth. These conditions would persist for a hundred million years.
