Overlooked material in Ryugu and meteorites may explain how water spared ancient chemistry
Source: Phys.org · Published
Asteroid Ryugu and some carbonaceous meteorites, which are thought to have similar origins in the early solar system, are known as chemically "primitive" materials because they preserve the chemical composition of the early solar system remarkably well. Yet these rocks also reacted extensively with water after they formed, transforming many of their original minerals into new ones.
