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 ...

Earth’s inner core may be made of fluid light elements swirling around amid a solid lattice of iron, according to a computer simulation study. A team of physicists recently modeled how alloys of iron ...

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 ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

A groundbreaking study published in Nature Communications offers new insights into Earth’s inner core, potentially solving long-standing mysteries about seismic anomalies. An international team led by ...

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