Researchers analyzing samples from asteroid Ryugu collected by Japan's Hayabusa 2 spacecraft in 2020 found all five nucleobases essential for DNA and RNA, strengthening evidence that asteroids may have delivered the chemical building blocks of life to Earth. The discovery, which adds to similar findings from asteroids Bennu and meteorites, suggests that nucleobases are widespread throughout the solar system and could have facilitated the emergence of early life on our planet.
