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.

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the transuranium element berkelium. According to a new study, the electronic signature of ...

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

Helium normally has trouble bonding with other elements, but researchers were able to crush atoms of iron and primordial helium together at extremely high heat and pressure to bond them in a ...

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 ...

A Pulsar Helium drill site as seen Jan. 13 near Babbitt, Minn. Canada-based Pulsar Helium has discovered extremely high concentrations of helium in tests of underground deposits. Helium is best ...

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

“Before the first stars exploded, there was no water in the Universe because there was no oxygen. Only very simple nuclei ...

Whereas helium-4 is a common product of the decay of radioactive elements, helium-3 comes almost entirely from the initial cloud of dust and gas that formed the solar system. This primordial ...
