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 ...

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.

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

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 ...

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 ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

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