Scientists have pinned Earth’s inner core temperature at roughly 5,400 degrees Celsius, a figure that rivals the surface of the Sun. That number rests on high-pressure laboratory experiments that ...

The iron-rich core at the centre of our planet has been a crucial part of Earth’s evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

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 ...

X-ray radiographic images before and during deformation experiments of hcp-iron at 16.5-17.5 GPa and 823-873 K. The sample strain during deformation was determined from these radiographs. Credit: Yu ...

Iron atoms form a rigid hexagonal close-packed (hcp) structure, with a subset of these atoms exhibiting collective motion along the [100] and [010] directions. Within this hcp iron lattice, ...
