Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in surprising and fascinating ways.

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

In 2025, scientists discovered that gold is escaping from Earth's core and the world's oldest rocks may be located in Quebec, ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
