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 ...

In June 2024, USC scientists published a study showing that Earth’s inner core has been slowing since 2010. This deceleration slightly affects the planet’s rotation, leading to marginally longer days.

In a recent discovery that could change how we understand Earth’s inner layers, scientists have found signs that precious metals like gold might be slowly leaking from the planet’s core. Until ...

Hot magma might’ve pushed material from Earth’s dense metallic core all the way to the surface. Plus, the absence of just one amino acid helps mice shed weight and groundbreaking scientific ...

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than previously thought ...

The center of the Earth, built up over 4.5 billion years, holds most of the Earth's precious metals. Indeed, more than 99.999% of the Earth's gold is thought to be locked in the core, along with ...

Contrary to conspiracy theories, the Earth’s core isn’t hollow. The dense, hot ball instead contains a stew of precious metals including platinum, ruthenium, and pretty much all of the planet ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...
