I hate the fact that this is getting wayyy more attention that JWST's recent discovery of CO2 and Methane in K2-18 b's atmosphere. Like that is actual evidence for alien life for fucks sake. We might actual have found the first extra solar life, and instead focus on some grifter.
the possible detection of dimethyl sulfide on K2-18 b by JWST is incredible. one of the most convincing leads i've seen so far.
So i'm not the most well versed in chemistry or biology but i know a fair bit of physics and geology, and i know that both CO2 and methane can form through geological processes. Which is why i was not that impressed by this news at first. But is there something more special about dimethyl sulfide that requires biotic processes? Couldn't it also just come from something like volcanic activity?
That's interesting.
