Not that exciting until they find other different biomarkers. Dead Comets have DMS: https://arxiv.org/abs/2410.08724 And the interstellar medium....

This is a terrible title. The original title was: "Astronomers have found the 'most promising signs yet' of alien life on a planet beyond our Solar System" "Astronomers have found signs of alien life on a planet beyond our Solar System" means something completely different. Please @dang update or this looks like the Daily Mail. It's an example of scientists acting irresponsibly. They might have found dimethyl sulfide but it can be produced abiotically. Dimethyl sulfide (CH3SCH3, DMS) signatures were found in comet 67P/Churyumov-Gerasimenko and that is for sure not Times Square on Saturday…
