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

A new study has found that Earth's innermost core isn't a conventional solid, but rather in a 'superionic state'.

Far below our feet, a giant may have started moving against us. Earth's inner core, a hot iron ball the size of Pluto, has stopped spinning in the same direction as the rest of the planet and might ...

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

The mystery over the potential age of Earth’s inner core may have been solved, after new data has revealed that it might have formed as early as 1-1.5 billion years ago. Trying to determine the actual ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

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, ...

For decades, researchers have known that Earth’s inner core behaves strangely, acting both solid and oddly soft at the same ...

The Earth's internal layers including the mantle, outer core, and inner core. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really means has been up for ...

Scientists have debated for years about what's going on with Earth's inner core. A new study offers compelling evidence that the inner core reversed direction and is slowing down. The shift happened ...

Recent scientific findings indicate a significant slowdown and reversal in the Earth's inner core rotation. This discovery, based on seismic wave analysis, sheds light on the core's behavior and its ...
