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

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 ...

Deep beneath our feet, far below the crust and mantle, researchers now argue that matter behaves in a way that does not fit the familiar categories of solid or liquid. At the center of Earth, they say ...

The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

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 ...

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

“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 ...

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

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 even be rotating the other way, research suggested on Monday.

Each year, the solid-iron inner core at the heart of our planet expands by about a millimeter as the Earth’s nether regions cool and solidify. According to a recent study, one side appears to be ...
