Oct 16, 2020 · Bennu is a primordial artifact preserved in the vacuum of space, orbiting among planets and moons and asteroids and comets. Because it is so old, Bennu could be made of material containing molecules that were present when life first formed on Earth.

1 day ago · Material from Asteroid Bennu is revealing that a lost world fostered the building blocks of life…with an unexpected twist. Join experts on Thursday, January 30 at 3:00 p.m. ET as they dive into the recent findings from the asteroid sample NASA’s OSIRIS-REx spacecraft brought to Earth in September 2023.

1 day ago · Bennu is a carbon-rich space rock known as a rubble pile asteroid. Scientists believe Bennu was once part of a larger “parent” asteroid that lost a few pieces due to an impact. Then, those ...

1 day ago · Bennu’s minerals offered crucial clues to how the asteroid formed — and how its amino acids and nucleobases developed along the way. The scientists concluded that the asteroid was a relic of a ...

2 days ago · Grabbing a bit of Bennu has been one of the most audacious missions Nasa has ever attempted. A spacecraft called Osiris Rex unfurled a robotic arm to collect some of the 500m-wide space rock ...
