Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

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 ...

These "nucleation" events are the first steps toward freezing. What they found was surprising: silicon and sulphur, elements often assumed to be present in the core, actually slow down the freezing ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

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 ...
