Samples of Bennu were brought back to Earth by NASA’s OSIRIS-REx spacecraft in 2023. Now, a pair of newly published papers ...

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

It took two years for NASA's OSIRIS-REx space probe to return from asteroid Bennu before dropping off a small capsule as it ...

Asteroids, small airless bodies within the inner solar system, are theorized to have contributed water and chemical building blocks of life to Earth billions of years ago. Although meteorites on Earth ...

Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu ...

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

NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.

"The detection of these key building blocks of life in the Bennu samples supports the theory that asteroids and their fragments seeded the early Earth with the raw ingredients that led to the ...

the asteroid’s amino acids hold a surprise. On Earth, amino acids in living organisms predominantly have a ‘left-handed’ chemical structure. Bennu, however, contains nearly equal amounts of these ...
