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 ...

A quirky material that behaves like a mishmash of liquid and solid could be hidden deep in the Earth. Computer simulations described in two studies suggest that the material in Earth’s inner core, ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

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 ...

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