Mystery of the Origins of the Earth’s Water: Sun Is a Surprising Likely Source

Fascinating information about the latest research of the likely source of water theory on Earth. There is so much we still don’t know for sure, but more and more things come to light as technology evolves. 

Mystery of the Origins of the Earth’s Water: Sun Is a Surprising Likely Source:

Curtin University researchers have helped unravel the enduring mystery of the origins of the Earth’s water, finding the Sun to be a surprising likely source.

A University of Glasgow-led international team of researchers including those from Curtin’s Space Science and Technology Centre (SSTC) found the solar wind, comprised of charged particles from the Sun largely made of hydrogen ions, created water on the surface of dust grains carried on asteroids that smashed into the Earth during the early days of the Solar System.

“Our research suggests the solar wind created water on the surface of tiny dust grains and this isotopically lighter water likely provided the remainder of the Earth’s water.

“This new solar wind theory is based on meticulous atom-by-atom analysis of minuscule fragments of an S-type near-Earth asteroid known as Itokawa, samples of which were collected by the Japanese space probe Hayabusa and returned to Earth in 2010.

“Our world-class atom probe tomography system here at Curtin University allowed us to take an incredibly detailed look inside the first 50 nanometers or so of the surface of Itokawa dust grains, which we found contained enough water that, if scaled up, would amount to about 20 liters for every cubic meter of rock.”
