Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

Researchers from the Australian National University (ANU) have discovered evidence suggesting that the Earth’s inner core is solid, according to a study published in the ...

Understanding inner core oscillations is key to grasping Earth's rotation variations and magnetic field changes, linking deep processes to surface effects.

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, ...

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 ...
