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

In 2023, NASA’s OSIRIS-REx mission returned from space with a sample of an asteroid named Bennu and scientists got to dive into a tale of rock, ice and water that hints at how life could have ...

The asteroid Bennu is puzzling scientists, with samples from the space rock showing weirder properties than they expected. These include extremely high nitrogen levels and improbably magnetic ...

This figure illustrates key molecules and minerals discovered in samples of near-Earth asteroid (101955) Bennu, which were delivered to Earth by NASA’s OSIRIS-REx mission in September 2023. Bennu is a ...

NASA’s OSIRIS-REx mission returned samples from asteroid Bennu, which showed discoveries about life and the early solar system. These findings can now provide information into the potential ...

New insights from NASA's OSIRIS-REx mission have unveiled intriguing clues about the potential origins of life on Earth. The mission, which launched in Septembe ...

Bennu’s parent body formed 4.5 billion years ago and once contained pockets of liquid water. As the water evaporated, brines similar to Earth’s salt flats remained.

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

Near-Earth asteroid Bennu has a slim chance of colliding with Earth in 2182. If it does, the impact could trigger a global winter that affects our planet for years.

There is a 1 in 2,700 chance the Bennu asteroid could hit Earth by 2182. An asteroid NASA's been tracking for nearly 25 years could impact Earth in the future, a new report reveals. First ...

A NASA spacecraft has returned asteroid samples that hold not only the pristine building blocks for life but also the salty remains of an ancient water world.

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 ...
