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 ...

The findings confirm that helium could stay locked in Earth's solid inner core for a long time, Olson told Live Science, but he cautioned that only 4% of the core is solid. "This is significant ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

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.

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

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 weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

We have discovered the oldest meteorite impact crater on Earth, in the very heart of the Pilbara region of Western Australia.

Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new piece of the puzzle has now emerged with the discovery that they have ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.
