“NASA’s James Webb Space Telescope may have discovered tentative evidence of a sign of life on a faraway planet. It may have detected a molecule called dimethyl sulphide (DMS). On Earth, at least, this is only produced by life. The researchers stress that the detection on the planet 120 light years away is “not robust” and more data is needed to confirm its presence. Researchers have also detected methane and CO2 in the planet’s atmosphere. Detection of these gases could mean the planet, named K2-18b, has a water ocean. Prof Nikku Madhusudhan, of the University of Cambridge, who led the research, told BBC News that his entire team were ‘shocked’ when they saw the results. ‘On Earth, DMS is only produced by life. The bulk of it in Earth’s atmosphere is emitted from phytoplankton in marine environments,’ he said.” (09/12/23)
