>>3452if this is real (again, i'd guess its not) there is a good chance its related to earth life. there are a pretty large amount of meteorites that were originally from mars before getting blown off into space by large asteroid impacts and then hitting the earth without being melted or anything, there is a good possibility that the same thing happened with the earth and any bacterial spores or whatever that survived might be able to survive on venus, or even the other way around

still this is probably due to some weird volcanism or something, iirc there was something similar to this with methane being detected in the atmosphere of mars but now the general consensus is that it is from some weird reaction between subsurface water, olivine, and co2
