Asteroid Bennu is the space rock with the highest known probability of hitting Earth in the next 200 years. NASA's OSIRIS-REx mission will help us protect ourselves.

Last month, NASA's OSIRIS-REx spaceship dropped off a sample of dirt from the Bennu asteroid. Scientists have been studying it ever since. The black rocky regolith, or debris, contains carbon and ...

A view of asteroid Bennu ejecting particles from its surface on Jan. 6, ... "sandpaper-like texture," said team member Andrew Ryan, a research scientist at LPL at the University of Arizona.

"Bennu has a salt-and-pepper kind of texture, bright grains and dark grains, and we're seeing that," says Lauretta. "In fact, as I was zooming around these images I felt like I was miniaturized ...

A space rock is making big news this weekend. And it could make even bigger news next century. Potentially hazardous near-Earth asteroid Bennu, the subject of NASA's OSIRIS-REx mission that's set ...

This asteroid is one of the most likely to hit Earth. Here’s what it means for our future. New ultraprecise measurements show that the asteroid Bennu has a higher chance than thought of ...

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.

Samples of matter returned from the asteroid Bennu support the theory that asteroids could have brought the building blocks of life to Earth, scientists report in a pair of new studies published ...

An early analysis of a sample collected from the asteroid Bennu suggests that the space rock had an unexpectedly water-rich past — and it may have even splintered off from an ancient ocean world ...

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 ...

NASA’s OSIRIS-REx asteroid probe has spotted the asteroid Bennu flinging pieces of its own surface into space. These “particle ejection events” happen all the time, … ...

Bennu — a rubble pile just one-third of a mile (one-half of a kilometer) across — was originally part of a much larger asteroid that got clobbered by other space rocks.
