Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

The Earth's inner core was once liquid ... which creates electric currents (through "dynamo action"), which generates our magnetic field. Ever wondered what keeps the northern lights dancing ...

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.

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 ...

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

Earth's mysterious core is yet again generating headlines as scientists learn more about what lies way beneath our feet. Located 3,000 miles below the Earth’s surface, the inner core is anchored ...

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

Scientists have raised concerns that the Earth's inner core may completely halt its rotation by 2040, according to a recent paper published in Nature. The study suggests changes are occurring deep ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
