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.

Our planet’s core is made mostly of iron, but it might also contain primordial helium that formed just after the Big Bang. Helium normally has trouble bonding with other elements, but researchers were ...

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 ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests ... crust is pulling apart and out of volcanic hotspots that tap magma from the ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

The Earth is made of different layers: the core, mantle and crust ... The upper mantle is hard but below that is semi-molten rock called magma. Crust The crust is the outer layer of the Earth ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests ... out of volcanic hotspots that tap magma from the deep mantle.
