The Ryugu Asteroid's Water Drop is a popular attraction that provides claims to the origins of life  ...

Specks of dust collected by a Japanese space probe from an asteroid 300 million kilometres from Earth have discovered a surprising component: a drop of water, according to experts. The discovery provides new support for the theory that life on Earth was seeded from outer space.

The findings are in the most recent research to be published following an analysis of 5.4 grams of rocks and dust collected by the Hayabusa-2 probe from the asteroid Ryugu.

"This drop of water has a real meaning," scientist Tomoki Nakamura of Tohoku University told reporters before of the research''s publication in the journal Science on Friday.

"Many scientists believe that water was brought from outer space, but we actually discovered water in Ryugu, an asteroid near Earth, for the first time."

F, who was sent to Earth two years ago, to remove a capsule containing the sample.

The precious cargo has already provided a lot of insight, including organic material that indicated that some of Earth''s key elements, including amino acids, might have been formed in space.

According to the study published Friday, the team found a drop of fluid in the Ryugu sample "which was carbonated water containing salt and organic matter." Nakamura said the group''s findings.

According to Nakamura, asteroids like Ryugu, or its larger parent asteroid, may have "provided water, which contains salt and organic matter" in collisions with Earth.

"We have discovered evidence that this (process) might have been directly related to, for example, the origin of the oceans or organic matter on Earth."

Nakamura''s team, which includes 150 researchers from the United States, Britain, France, Italy, and China, is among the largest teams conducting an analysis of Ryugu''s sample.

To increase the chances of new discoveries, the sample has been divided into different scientific teams.

Kensei Kobayashi, an astrobiology expert and professor emeritus at the Yokohama National University who isn''t part of the research group, was praised for the discovery.

Given its fragility and the possibility of it being destroyed in outer space, he told AFP. "The fact that water was discovered in the sample itself is shocking."

"It does suggest that the asteroid contained water - in the form of fluid and not just ice - and organic matter might have been generated in that water."
