Possible signs of life have been detected on the exoplanet K2-18b.

Scientists from Cambridge, using the James Webb telescope, have detected molecules of dimethyl sulfide and dimethyl disulfide in the atmosphere of an exoplanet orbiting the red dwarf K2-18.

Dimethyl sulfide is formed on Earth during the life processes of some marine algae. It is also the most common sulfur compound of biological origin emitted into the atmosphere.

Planet K2-18b is a super-Earth, and signs of water in the atmosphere have previously been detected on it.
