New observations by NASA's OSIRIS-REx spacecraft suggest that the 1,650-foot-wide (500 meters) Bennu harbors lots of water, a key resource that prospective asteroid miners aim to target.

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.

Bennu’s parent body formed 4.5 billion years ago and once contained pockets of liquid water. As the water evaporated, brines ...

This combination of rock, water and organics is one reason OSIRIS-REx chose to sample the organic-rich asteroid Bennu, where ...

NASA says Bennu asteroid sample shows evidence of water, carbon 00:24. Rocks and soil collected from the asteroid Bennu and brought back to Earth last month by NASA's OSIRIS-REx probe are rich in ...

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.

Bennu has long intrigued researchers due to its near-Earth orbit and carbon-rich composition. Scientists theorized that the asteroid contained traces of water and organic molecules and that ...

This combination of rock, water and organics is one reason OSIRIS-REx chose to sample the organic-rich asteroid Bennu, where water and organic compounds essential to the origin of life could be found.

They’re the building rocks of life. Analysis of debris from the nearly 5 billion-year-old asteroid Bennu suggests the ingredients to life on Earth were present in the early days of our solar ...

Bennu is a roughly 0.3-mile-wide (500 meters) asteroid that orbits in near-Earth space. Scientists suspect it’s a chunk of a larger asteroid that broke off due to a collision farther out.

Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission from a near-Earth asteroid named Bennu.

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 ...
