Scientists have coaxed one of the universe’s most stubborn elements into a new compound. Formed under intense pressures, the newly discovered compound packs helium atoms into crystalline iron, ...

The surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron helide means we may have misunderstood the chemistry making up the ...

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 ...

The diamond anvil crushed iron and helium together under conditions mimicking those inside the Earth, to create a new compound. These compounds remained stable when pressures were reduced. Further ...

Helium-3, a rare isotope of helium gas, is leaking out of Earth’s core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. When you purchase through ...
