“The results of the experiments summarized in this work, focused on surface bombardment with hydrogen atoms, clearly confirm the theory of the interaction of excited hydrogen or deuterium
Rydberg atoms and ions with the surface oxygens of oxide minerals,” the authors explain. “Our experiments attempt to explain the origin of water in the areas of oxygen-containing solid material (e.g., dust, meteoroids, asteroids, comets) exposed to a stream of charged particles close to a parent star.”
Earth’s atmosphere and magnetosphere shield it from the solar wind, so there’s no way the wind could’ve created water right on Earth’s surface. However, as the study shows, the wind can create water on the surface of other bodies like asteroids, and the water can be adsorbed and held firm, then delivered to Earth via impacts.
“This scenario is also applicable to the origin of water on Earth,” the authors write. “Due to this effect, a water molecule can be adsorbed on the surface of oxygen-containing particles and then transported over long distances and times,” the researchers write.
This study won’t be the end of the ongoing effort to account for Earth’s water. In a fascinating roundabout way, this research brings us back to asteroids and meteorites delivering Earth’s water.
