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, ...

Forget a doomsday asteroid or melting permafrost. It’s the freezing of Earth’s core that will end the world in today’s episode. Or would it? Because maybe, just maybe, we could save the world by ...

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 ...

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, reversing its spin, is weirdly textured, and contains an unusual state of ...

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 ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

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 ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Alfred Wilson-Spencer receives funding from the Natural Environment Research Council (NERC) grants NE/T000228/1 and NE/V010867/1. He works for the University of Leeds. The iron-rich core at the centre ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...
