Asteroid samples leaves Japanese scientist 'speechless'

Scientists hope dust will shed light on formation of universe and offer clues about how life began on Earth

Scientists in Japan said they were left amazed when they saw how much asteroid dust was inside a capsule delivered by the Hayabusa-2 space probe.

The Japanese probe collected surface dust and pristine material last year from the asteroid Ryugu, about 200m miles (300m km) away, during two daring phases of its six-year mission.
