Deep beneath the surface of our planet lies the Earth’s core, a solid ball of iron under crushing pressure. Now, however, scientists conducting laboratory experiments have found evidence suggesting it ...

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 ...

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 ...

In work published in Science Advances, a team of researchers have determined a new pressure scale, which is critical for understanding the Earth’s composition. Using x-rays from a uniquely powerful ...

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 ...

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 ...
