Study: The water covering the Earth’s surface was formed in space with the help of wind


A new study conducted on space dust showed that the water that covers most of the Earth’s surface could have formed in space with the help of the solar wind, according to Sky News Arabia.

According to the study, the results of which were published in the journal “Nature Astronomy”, an international team of scientists tested samples taken from the asteroid “Itokawa”, collected by the Japanese space probe “Hayabusa” in 2010.

Scientists used tomography to measure the atomic composition of dust grains on the asteroid, and to detect water molecules.

The researchers found that the water molecules in Itokawa were formed when hydrogen ions flowing from the sun collided with dust particles on space rocks, altering their chemical composition.

Luke Daley, the study’s lead author, from the University of Glasgow’s School of Geographical and Earth Sciences, said: “Over time, hydrogen ions can expel enough oxygen atoms from the materials in the rock to form water trapped within the existing minerals. on the asteroid.

Daly stressed that the study may be a key to explaining a decades-old theory that asteroids brought water to Earth, when the planet formed about 4.6 billion years ago, according to Sky News.
