Black sandy dust found in a capsule brought to Earth by a Japanese space probe is from the distant asteroid Ryugu, scientists confirmed after opening it on Monday. The discovery comes a week after the Hayabusa-2 probe dropped off its capsule, which entered the atmosphere in a streak of light before landing in the Australian desert and then being transported to Japan. The Japanese space agency (JAXA) released a picture of a small deposit of sooty material inside the metal box — a first glimpse at the results of an unprecedented six-year mission for the unmanned probe.
