For decades, scientists have puzzled over traces of primordial helium—a rare isotope known as ³He—escaping from volcanic rocks in places like Hawaii and Iceland. Unlike the more common ⁴He, which is ...

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

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

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

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.

A rare isotope from the early solar system may be locked in Earth's core, revealing insights into planetary formation ...

Mining the moon for water, helium-3, and rare earth elements could become a multibillion-dollar industry in the near future, but astronomers warn it risks coming at the expense of scientific ...

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 ...

This rare form of helium is called helium-3 ... You wouldn't get much helium deep in the Earth if the Earth formed that slowly." In other words, if scientists can show that Earth's core contains ...

Scientists discover Earth may have huge quantities of helium ... debate about how quickly our planet formed. This rare form of helium is called helium-3 because it has two protons and one neutron ...
