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,

Bennu samples brought back by a University of Arizona-led space mission contain the key ingredients of life and signs of the stew needed to mix them.

Samples from asteroid Bennu have delivered insights into the origins of Earth’s water and the organic molecules that may have seeded life.

Samples of organic matter returned from the asteroid Bennu support the theory that asteroids could have brought the building blocks of life to Earth.

Samples of asteroid Bennu contain molecules that suggest the "conditions necessary for life" were widespread across the early solar system, according to NASA.

Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose.

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

NASA reaffirms its plan with SpaceX to return two astronauts from the ISS, following President Trump's remarks. Another breakthrough involves samples from asteroid Bennu, which hold chemical building blocks of life,

The latest discovery, unveiled by the NASA on January 29, came as a bit of a surprise and posed many exciting questions such as “Why didn’t life form on Bennu?”

The meteor fragments returned by OSIRIS-REx shed light on the entwined history of water and the chemical ingredients of life in the solar system.

CAPE CANAVERAL, Fla. — Asteroid samples fetched by NASA hold not only the pristine building blocks for life but also the salty remains of an ancient water world, scientists reported Wednesday.
