With an estimated 6 sextillion kilograms of the stuff—that’s 21 zeroes by the way—the Earth’s core is another example of why ...

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.

Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a major storage place for hydrogen, possibly equivalent to dozens of oceans’ ...

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 ...

Old crystals found in Western Australia are drawing fresh attention from geologists studying how the planet first took shape.

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

Multiple impacts on Earth might better explain our moon’s origin than a single giant impact 4.5 billion years ago – and could help solve one of its biggest mysteries. Pinning down the origin of our ...

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 ...

Just in time for Valentine's Day, space offers a heart-shaped greeting. The star Mira A, about 300 light-years from Earth, ...

Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

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 ...

(Nanowerk News) A team of researchers, led by a University of Hawai‘i (UH) at Mānoa planetary scientist, discovered that high energy electrons in Earth’s plasma sheet are contributing to weathering ...
