More than 70% of the earth is covered by water. The scientific community has been trying to solve the mystery of the earth’s water source. On Monday, a scientist published a new inference in the British Astronomy Journal “Nature Astronomy”. The asteroids containing the constituent water are brought to the earth, forming today’s abundant water source.
In the past, academic circles believed that the earth’s water came from C-type asteroids containing carbon, but the isotopes of this type of asteroid did not match the earth’s water, which proved that there may be another set of more reliable theories.
Researchers from the University of Curtin, Western Australia, Australia and the University of Glasgow, Scotland, analyzed the fragments of the “Ishikawa” S-type asteroid brought back to Earth by the Japanese Hayabusa probe in 2010. From particle-by-atom observation, it was found that this is the second The near-Earth asteroids in the large constellations contain water with lighter isotopes, which may provide a water source for the earth.
Researchers said that if you zoom in on the water content of the analyzed fragments, it is believed that each S-type asteroid contains 20 liters of water. Daly, who participated in the research, believes that it will help future space missions overcome the problem of replenishing water.
