These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Scientists have uncovered surprising evidence that helium, a gas long thought to be chemically inert, may actually bond with ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

Scientists have made a surprising discovery about the Earth's core that is almost like something out of science fiction. A ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
