The @haya2e_jaxa mission collected 5 grams of material from the near-Earth asteroid #Ryugu.
A special issue of Science described lab analyses of the samples, revealing Ryugu's composition, formation process, and history. Learn more on #AstronomyDay: https://scim.ag/2qw #press

Les équipes analysant les échantillons de l'astéroïde #Ryugu ont détecté la présence d'uracile, l'une des "lettres de l'alphabet génétique" de l'ARN. Un très beau succès (un de plus !) pour la mission japonaise #Hayabusa2. Ca ne veut évidemment pas dire qu'il y a de la vie sur Ryugu, mais que ce type d'objet a pu apporter sur Terre des ingrédients importants pour l'émergence de la vie.
J'ai répondu à ce sujet à une courte interview de la @RTSInfo

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

Na asteroidu #Ryugu byl nalezen uracil, jeden ze základních kamenů #RNA. K tomu i další významné organické látky jako třeba niacin (vitamín B3).
Life finds a way.

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."
