Water Drop Discovered on Ryugu Asteroid Offers Clues to Origins of Life on Earth

Specks of dust retrieved by a Japanese space probe from an asteroid some 300 million kilometres from Earth have revealed a surprising component: a drop of water, scientists said Friday. The discovery offers new support for the theory that life on Earth was seeded from outer space.

The findings are in the latest research to be published from the analysis of 5.4 grams of rocks and dust gathered by the Hayabusa-2 probe from the asteroid Ryugu.

“This drop of water has great meaning,” lead scientist Tomoki Nakamura of Tohoku University told reporters ahead of the research’s publication in the journal Science on Friday.
