Chinese researchers have discovered that interstitial carbon in iron-carbon alloys behaves in a superionic, liquid-like state under Earth’s core pressure and temperature conditions. Beneath Earth’s ...

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 ...

Planet Earth's inner core may have stopped turning and could go into reverse, according to a study published this week. Earth is formed of three layers: the crust, the mantle, and the core. Made ...

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 ...

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 ...

(NEXSTAR) – Deep in the center of the Earth is the inner core, which spans roughly 746 miles and is composed of primarily pure, solid iron, NASA explains. Though we’ve long believed – and research has ...

“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 ...

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 ...

Deep earth may be slowing its roll. Earth’s solid iron inner core appears to be spinning at a slower rate than the planet, according to a new study — but no worries, scientists believe it’s been ...
