Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Researchers have found evidence of changes in the structure of the Earth's core. University of Southern California team, led by Professor John Vidale, was investigating the inner core's rotation – a ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird ...

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...

A geomagnetic field is generated in Earth's interior and extends into outer space to protect Earth from cosmic radiation and the charged particles of solar wind. The magnetic field is generated by the ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.
