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 ...

Deep beneath our feet, far below the crust and mantle, researchers now argue that matter behaves in a way that does not fit ...

A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s innermost layer is changing shape. Scientists who just months ago ...

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

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 ...

“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 ...

(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 ...

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 ...
