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 ...

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 ...

This composition resembles models proposed for the inner core. The anisotropy displayed by hcp–Fe–2Si–0.4C at core conditions aligns well with the anisotropy reported by seismic studies for the outer ...

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

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 ...

An earthquake originating from Alaska caused seismic waves to penetrate the innermost inner core of the Earth. (Credit: Drew Whitehouse, Son Phạm and Hrvoje Tkalčic) Planet Earth is a marvelous ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

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 ...
