Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest 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 ...

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 ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

“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 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 ...

(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 ...

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 ...
