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

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

Plutonium discovered at the bottom of the ocean was found to be refuse from a kilonova that exploded close to Earth 10 ...

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.

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.

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

You might have read last year about a potentially significant deposit of helium found underground near Babbitt in northern Minnesota. That part of the state has long been known as a source for ...

Finding oxygen is a big deal. Only hydrogen and helium (with a sprinkle of lithium) formed in the Big Bang. All the other ...

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 ...

While NASA struggles with helium leaks on its Starliner spacecraft, Chinese researchers have found a novel way to use this gas to improve missile performance. This discovery could revolutionize space ...
