Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's essential ingredients.

Scientists said they didn't find evidence of life on Bennu, but they did find evidence of the building blocks of life.

NASA OSIRIS-REx asteroid sample return team has revealed exciting evidence of the precursors of life in the pieces of space rock Bennu.

Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission. NASA’s OSIRIS-REx mission brought back 121.6 grams of asteroid Bennu,

The discovery is a capstone achievement for NASA, which went to great lengths to secure and deliver asteroid samples from asteroid Bennu in 2020.

The building blocks for life, including salts, organic matter and amino acids have been found in samples returned to Earth from outer space.

In samples NASA brought back from the asteroid Bennu, scientists have discovered of organic compounds, including key building blocks of life like amino acids.

Scientists from NASA and other institutions who analyzed a sample of the asteroid Bennu delivered to Earth last September made an interesting and impo

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 organisms.

NASA's OSIRIS-REx space probe dropped off samples of asteroid Bennu in 2023, and now those samples have been analyzed by researchers for their contents.
