Amino acids discovered in samples from the Bennu asteroid may have formed in an icy, radioactive environment in the early solar system, according to a new study led by Penn State researchers. The findings challenge long-held assumptions that these building blocks of life on asteroids formed primarily in the presence of warm liquid water.
