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.

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 ...

Massive helium reservoir in Minnesota is even more 'mind-boggling' than we thought, new data suggest The Hamersley Province holds more than 55 billion tons (50 metric gigatons) of iron ore ...

"In this case, we crushed iron and helium together under about 5–55 gigapascals of pressure and at temperatures of 1,000 Kelvin to nearly 3,000 Kelvin. Those pressures correspond to roughly ...

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. Primordial helium from the ...
