Scientists have pinned Earth’s inner core temperature at roughly 5,400 degrees Celsius, a figure that rivals the surface of the Sun. That number rests on high-pressure laboratory experiments that ...

While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is ...

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 magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other shifts at ...

Earth’s inner core is surprisingly soft, and wiggling iron atoms may help explain why. The innermost part of our planet is a solid iron ball smaller than the moon and almost as hot as the surface of ...

Earth's inner core is filled with a rare material known as 'extreme hydrogen', a study has claimed.
