Earth's core has been a growing topic of interest. It is responsible for the planet's magnetic field, which protects life from the sun's radiation. Despite its importance, ...

The 2003 disaster film "The Core" imagines that the rotation of Earth's center has stalled, damaging the magnetic field that envelops the planet — and triggering a violent lightning storm that ...

According to scientists, about 99% of the Earth’s gold is buried deep within the planet’s metallic core — far beyond human reach.But researchers from the University of Göttingen in Germany ...

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

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

Essentially, if the rocks had more 100 Ru than it “ought” to, as part of the Earth’s crust, that’s a pretty good sign that it originally came from the core, some 3,000 kilometers (1,864 ...

Earth's rotation is speeding up, causing days to shorten by a fraction of a second since 2020. Scientists predict that a leap ...

What would happen if you put a baseball-sized piece of neutron star on the Earth? Would it fall to the core of the Earth and ...

Our planet's core is rich in gold that can leak out into the mantle, and in some cases, end up in volcanos on the surface, according to a new study.
