Scientists say they’ve confirmed Earth’s inner core has been slowing down. Here’s what it could mean — and why the topic has been the subject of fierce debate.

The rotation of Earth’s inner core may have paused and it could even go into reverse, new research suggests.. The Earth is formed of the crust, the mantle and the inner and outer cores. The ...

Earth's inner core is a roughly moon-size chunk of solid iron and nickel that lies more than 3,000 miles (4,800 kilometers) below our feet. It is surrounded by the outer core — a superhot layer ...

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

More than 5,000 kilometers beneath us, Earth's solid metal inner core wasn't discovered until 1936. Almost a century later, we're still struggling to answer basic questions about when and how it first ...

The inner core apparently started rotating in rough synchrony with the rest of Earth around 2009 and, as of now, it actually rotates at a slower pace than the rest of the planet.

As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it is still extremely hot, at least 5,000 Kelvin (K) (4,726.85°C) .

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 changing speeds and directions ...

The Earth’s inner core is separated from the rest of the solid Earth by its liquid outer core, so it rotates at a different pace and direction than the planet itself.

The new research from the University of Southern California, now published in Nature, noticed that the Earth’s inner core was moving slower than the surface, termed “backtracking,” and has ...

The rotation of Earth’s inner core may have paused and it could even go into reverse, new research suggests.. The Earth is formed of the crust, the mantle and the inner and outer cores. The ...
