Would the bags of poop left on the moon by moon landers (or future human exploration or habitation) count, if a different person "found" them? Ideally not but the letter of the market seems to indicate "yes"?

@Lorxus Scroll down. (As I didn't.)

Actually JAXA Hayabusa2 discovered amino acids on asteroid 162173 Ryugu which it reached on 27 June 2018. I don't know if this was the first such discovery. https://www.nature.com/articles/s41467-023-37107-6

@HarrisonNathan Just read @Daniel_MC 's comment below. Apparently it's not the first.

Rosetta found amino acids on a comet in 2014.

The Murchison meteorite, which fell in Australia in 1969, is one of the most studied and contains over 70 different amino acids.

@Daniel_MC Rosetta was comet 67P/Churyumov-Gerasimenko

One way to interpret this would be finding an allotrope of carbon - coal, graphite, diamond, buckminsterfullerene - in space.

At least for non-planetary bodies, I'd imagine we've already found diamond (some gas cloud or something like that).

Does methane count as a carbon molecule? Do do you mean e.g. an amino acid?

@TheAllMemeingEye Amino acids, yes. Not simple molecules. Thanks for asking!

@WalterJr Is this strictly amino acids or does anything else also count? Can you change the title to clarify?

@HarrisonNathan seconding this request, "carbon molecule" is entirely too vague. my first reaction to seeing this market was "Titan's atmosphere is mostly hydrocarbons and I'm pretty sure they've already detected carbon on the moon and mars"
