New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

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 ...

The solid inner core (610 km radius) found by Huixing Bi and colleagues is hugely significant. The very presence of a solid inner core shows that crystallization and solidification is taking place as ...
