A tiny fragment from the most dangerous asteroid in the solar system has arrived in the U.K. — and scientists think it could teach us about the origins of life on Earth.
The fragment — a millimeter-size (0.04 inch) slice from the roughly 6-ounce (170 grams) sample that was collected from the asteroid Bennu and may contain the precursors to life — arrived at the Natural History Museum in London Tuesday (Nov. 28).
