Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a theory that our planet has a distinct ball of iron within its metallic core.

A new study reveals Earth's essential features formed within its first 100 million years, challenging long-held theories.

Our Earth is structured sort of like an onion – it's one layer after another. Starting from the top down, there's the crust, which includes the surface you walk on; then farther down, the mantle, ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU). By ...

It’s time to rewrite science textbooks. In a study, scientists claim to have discovered another layer in the Earth’s core. For many years, it has been widely believed that the Earth has four layers: ...

There is more to the Earth than what we can see on the surface. In fact, if you were able to hold the Earth in your hand and slice it in half, you'd see that it has multiple layers. But of course, the ...

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. The finding was made by measuring ...

Earth might have more layers than scientists thought. New research finds that there may be a hidden layer inside the Earth's solid inner core — an inner-inner core, if you will. The precise nature of ...

A new study suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. A new study from a University of Chicago scientist suggests there may be ...
