Prof. Nikku Madhusudhan, a Cambridge University astrophysicist, says the discovery of two gases — dimethyl sulfide, or DMS, and dimethyl disulfide, or DMDS — in the atmosphere of a planet will be seen as a 'paradigm shift in our search for life.' Scientists used NASA's James Webb Space Telescope to make the discovery about K2-18 b, a planet found about 124 light-years from Earth.
