New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

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

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, reversing its spin, is weirdly textured, and contains an unusual state of ...

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 ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able to ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

Researchers in England believe carbon played a key role in freezing Earth’s core. As it contributes to the cooling and freezing of the molten outer core, the solid, iron-rich center of Earth continues ...
