However, researchers from the University of Southern Carolina (USC) now say they discovered — almost by accident — that the ...

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.

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) .

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.

Earth’s inner core — like a planet inside another planet — appears to move to its own beat. A team of scientists previously found that it has been spinning at slightly different speeds than ...

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) (4726.85 degrees Celsius) .

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...

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 ...

While it's unlikely the deep-buried treasure chest will ever be cracked open, scientists call the discovery significant.

The Earth is leaking. The good news is this isn’t bad news, because the Earth is leaking gold and other precious metals.

Scientists identified a heartbeat-like rhythmic pulse trapped within the Earth — and say it has profound implications for a ...
