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 ...

YR4 became the highest-rated asteroid predicted to strike Earth, and although predictions for impact have lowered, not enough ...

The asteroid Bennu has been at the centre of scientific discussions recently, especially after researchers analysed surface samples collected by NASA’s OSIRIS-REx mission. While much of the ...

Many biological molecules are chiral, meaning they exist in two forms that are mirror images of each other, like left and ...

NASA spacecraft touched down on the rugged surface of the Bennu asteroid on Tuesday, grabbing a sample of rocks dating back to the birth of our solar system to bring home. The minivan-sized OSIRIS ...
