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

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through ...

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

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 ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth's crust through its core. The very center of the planet, a solid ball of iron and nickel ...

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 ...

Chinese researchers have discovered that interstitial carbon in iron-carbon alloys behaves in a superionic, liquid-like state ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...

“It’s probably benign, but we don’t want to have things we don’t understand deep in the Earth.” Now, a recent study published in the scientific journal Nature Geoscience reveals a curious new detail ...

An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior ...
