Samples of #asteroid #Ryugu collected by #Hayabusa2 had #uracil, one of the informational units that make up #RNA, the molecules that contain the instructions for how to build and operate living organisms. Vitamin #B3 or #niacin, which is an important cofactor for #metabolism in living organisms, was also detected in the same samples

Uracil in the carbonaceous #asteroid (162173) Ryugu: https://www.nature.com/articles/s41467-023-36904-3 - the "initial analysis team for the soluble #organic matter reported the detection of wide variety of organic molecules including racemic amino acids in the Ryugu samples. Here we report the detection of #uracil, one of the four #nucleobases in ribonucleic acid, in aqueous extracts from #Ryugu samples."
