By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird ...

Deep inside Earth, researchers see signs that the solid inner core may be arranged in multiple chemical layers far below.

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

Researchers in England believe carbon played a key role in freezing Earth’s core. As it contributes to the cooling and freezing of the molten outer core, the solid, iron-rich center of Earth continues ...
