Scientists studying samples from the asteroid Bennu have found that it contains a remarkable mix of materials — some of which formed long before the sun even existed. "It's very fascinating to see ...

NASA's first asteroid sample is the most pristine sample of its kind. Now, back on Earth, the sample from asteroid Bennu has already delivered surprising findings about the early solar system and ...

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. Telescope ...
