A new study conducted on space dust revealed that the water that covers the majority of the planet’s surface could have formed in space with the help of the solar wind.
An international team of scientists tested samples taken from the asteroid “Itokawa”, collected by the Japanese space probe “Hayabusa” in 2010, using tomography to measure the atomic composition of dust grains on the asteroid, and the discovery of water molecules, according to the study published in the journal “Nature Astronomy”.
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.
Professor Luke Dalian, School of Geographical and Earth Sciences at the University of Glasgow, confirmed 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.”
