New Study Finds Earth's Water Originated from Native Hydrogen, Not Asteroids

Earth’s Water Origin Unlocked: Meteorite’s Hidden Hydrogen Surprise

Oxford researchers have unearthed a cosmic surprise showing that the hydrogen needed for water was embedded in the very rocks that formed Earth. Researchers at the University of Oxford have challenged the widely held theory that Earth’s water came from asteroid impacts. They studied a rare meteorite that closely resembles the material that formed the [...]

Water properties under nano-scale confinement

Water is the universal solvent and plays a critical role in all known geological and biological processes. Confining water in nano-scale domains, as encountered in sedimentary rocks, in biological, and in engineered systems, leads to the deviations in water’s physicochemical properties relative to those measured for the non-confined phase. In our comprehensive analysis, we demonstrate that nano-scale confinement leads to the decrease in the melt…

New evidence 'challenges theories on the origin of water on Earth'

Researchers say they have uncovered evidence that early Earth was home to more hydrogen than previously thought, calling into question widely held beliefs about the origins of water and the evolution of our planet.Scientists from the University of Oxford analysed a rare type of meteorite known as an enstatite chondrite. The space rock dates to around 4.6 billion years ago and is believed to be similar in composition to early Earth, according to …

New evidence challenges theories on the origin of water on Earth, study suggests

(CNN) — Researchers say they have uncovered evidence that early Earth was home to more hydrogen than previously thought, calling into question widely held beliefs about the origins of water and the evolution of our planet.

Origins of Earth's Water May Not Be as Complicated as We Thought

Given the seeming paucity of moisture in the leftover remains of Earth's building blocks, planetary scientists have long assumed our planet's water supply came after it formed in a rain of hydrogen-soaked rocks and comets.

Earth’s water may not have originated from asteroids after all

With water covering the majority of our planet, scientists have been wading through ideas to answer a fundamental question: Where did it all come from? A...
