Asteroid Bennu seems to have come from a long-lost world on the fringes of the solar system, where saltwater pooled and dried over thousands of years and life’s basic ingredients were widespread.

This artist’s concept shows NASA’s OSIRIS-REx spacecraft descending towards asteroid Bennu to collect a sample of the asteroid’s surface. NASA/Goddard/University of Arizona Scientists studying the sample collected in 2023 from asteroid Bennu have announced a dramatic finding: they have identified the key building blocks of life within the sample.

Two science teams pored over samples from the B-type asteroid Bennu, finding chemicals linked to the beginnings of life and brine that is of interest for future space exploration.

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

Material retrieved from the asteroid Bennu by NASA’s OSIRIS-REx spacecraft shows that all the basic building blocks of life were astonishingly widespread in the early solar system

Scientists detected all five nucleobases -- building blocks of DNA and RNA -- in samples returned from asteroid Bennu by NASA's OSIRIS-REx mission.

Analyzing a sample from an asteroid named Bennu reveals the chemicals necessary to form DNA and RNA.

Rock and dust samples brought back from the near-Earth asteroid Bennu contain organic matter, including amino acids and all five DNA and RNA bases, as well as salts that formed early in the history of Bennu's parent body.
