Space spat: Webb hints at life — but not everyone’s buying it
Initial excitement over potential alien life signs on exoplanet K2-18b, based on dimethyl sulfide (DMS) detection by the James Webb Space Telescope, has been tempered by subsequent analyses. Led by Cambridge University's Nikku Madhusudhan, the initial findings suggested the presence of DMS, a potential biosignature. However, re-analysis by other researchers, including Madhusudhan's former students, using different statistical models, found insufficient evidence to support the claim, suggesting the initial detection may have been a statistical fluke.
