According to a paper published in the journal Nature and Astronomy on the 29th, an international research team led by the University of Glasgow in the UK found that water on the ground may come from the "sky"-the sun
Phil Brand, director of the Space Science and Technology Center of Curtin University, Australia, said that compared with other rocky planets in the solar system, the earth's water resources are very rich, and the ocean covers about 70% of the earth's surface area
Brand said: "Existing theories suggest that water was brought to Earth in the final stage of the formation of C-type asteroids (carbon-containing asteroids)
This study shows that the solar wind produces water on the surface of tiny dust particles, and this lighter isotope water is likely to provide a source of water for the earth
S-type asteroids are asteroids with silicon as the main component and are the second largest group of stars after C-type asteroids
The world-class atom probe tomography system at Curtin University in Australia allows researchers to observe in great detail the nano-scale dust particles on the surface of the "Ishikawa" asteroid

"How astronauts can get enough water without carrying supplies is one of the obstacles to future space exploration
