The #evolution of #organic #material on #Asteroid 162173 #Ryugu and its delivery to #Earth https://www.nature.com/articles/s41467-024-50004-w
Studies of samples of asteroid Ryugu returned by the Hayabusa-2 mission show that the action of water and organic material on carbonaceous asteroids lead to the widespread occurrence of micron-sized #polymeric organic particles encapsulating clays and biological relevant #molecules.
