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

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

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

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 ...

The surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

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

The secret to unlimited energy may have been right below our feet the entire time, scientists say. But harnessing it will be a challenge.

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 ...

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

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

In other words, if scientists can show that Earth's core contains a lot of helium-3, it will strongly suggest that the planet formed quickly, settling a long-standing debate about the birth of the ...
