The volume of the ocean, its average purity, and the chemical makeup of H₂O allow a simple estimate of the amount of hydrogen ...

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across ...

High-energy electrons in the Earth's plasma may be contributing to the formation of water on the surface of the moon, a study found. The findings were published by a team of researchers, led by a ...

A planet-forming disk with more water than all of Earth's oceans has been discovered. The disk, which is located in the constellation Taurus, is 450 light-years away from Earth. Astronomers used the ...

Planetary scientists have discovered that high energy electrons in Earth's plasma sheet are contributing to weathering processes on the Moon's surface and, importantly, the electrons may have aided ...
