The Bennu samples contain 14 of the 20 amino acids that are essential for life on Earth to build proteins. Also found were all five of the basic building block for life — Guanine, Cytosine, Adenine, ...

Scientists have since been analyzing these samples to uncover their chemical composition. Bennu is classed as a near-Earth asteroid, meaning that it makes its closest approach to Earth every six ...

Asteroid Bennu is thought to be made of rubble fragments from a 4.5-billion-year-old parent body, containing materials that originated beyond Saturn, which was destroyed long ago in a collision ...

Researchers have detected organic compounds and minerals necessary for life in unprecedented samples collected from the near-Earth asteroid ... like Bennu once acted like giant chemical factories ...

NASA’s OSIRIS-REx mission returned from space with a sample of an asteroid named Bennu, similar to the one that rained rocks over Revelstoke. Our research team has published a chemical analysis ...

"They may be due to differences in parent bodies or formation pathways, or the Bennu asteroid was exposed to a cold molecular cloud environment where pyrimidine formation is more likely to occur." ...

Overall, they write, a Bennu-type asteroid could lead to “severe environmental consequences,” reducing land photosynthesis by 36 percent and marine photosynthesis by 25 percent. That would in ...

including some never before seen in asteroid samples. “This is all very exciting because it suggests that asteroids like Bennu once acted like giant chemical factories in space and could have ...

This mosaic image of asteroid Bennu is composed of 12 images taken by the OSIRIS-REx spacecraft from ... [+] a range of 15 miles. As wide as The Eiffel Tower is tall, the asteroid Bennu is a ...

In 2018, NASA’s OSIRIS-REx mission reached asteroid 101955 Bennu. Two years later, the spacecraft snagged a sample of its surface, which has since been returned to Earth. Now, astronomers are ...
