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

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.

Experts hope the minerals they find via this method will “power green, renewable energy sources for a sustainable future.” ...

For decades, noble gases like helium have been considered chemically inert, refusing to form stable bonds under normal conditions. But new research challenges this assumption, revealing that helium ...

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

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

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

The two giant blobs — one beneath the Pacific Ocean and one beneath Africa — lie at the boundary between Earth's mantle and its outer core ... boundary between two crystals, known as a ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with iron under high pressures. They used a laser-heated diamond anvil cell to ...

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 ...

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