Two new studies from the asteroid Bennu reveal pre-biology deep in space.

Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research.

WASHINGTON : Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that such space rocks may have seeded early Earth with the raw ingredients that fostered the emergence of living

Scientists report the detection of amino acids, polycyclic aromatic hydrocarbons, ammonia and other compounds, as well as a variety of salts, including sodium carbonates, phosphates, sulfates, and chlorides, in the Bennu samples.
