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.

NASA scientists discovered a plethora of precursors to life on the asteroid Bennu, demonstrating the importance of Earthbound sample-return missions.

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.

The study of asteroid samples is a highly lucrative area of research and one of the best ways to determine how the Solar System came to be. Given that asteroids are leftover material from the formation of the Solar System,

Japanese collaborators detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA's OSIRIS-REx

Scientists found 11 minerals in Bennu samples, including calcite, halite, and sylvite, that form when water with dissolved salts evaporates over time, leaving solid crystals. Similar brines have been detected on Ceres and Enceladus.

Pristine samples of the asteroid Bennu transported to Earth contain the "basic building blocks" for life, shedding new light on the perennial question of how life began on our planet.

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

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

NASA’s OSIRIS-REx mission returned 121.6 grams of sample from asteroid (101955) Bennu in September 2023—the largest sample ever returned to Earth. Now, an international team of OSIRIS-REx ...
