The iron-rich core at the centre of our planet has been a crucial part of Earth’s evolution. The core not only powers the ...

We know the temperature of Earth ’s inner core is very roughly about 5,000 Kelvin (K) (4,727°C). It was once liquid, but has cooled and become solid over time, expanding outwards in the process. As it ...

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able to ...

New research reveals that carbon made it possible for Earth’s molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth’s deep interior — and ...

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 ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...
