The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs ...

This appears to be the case, to a rather stunning extent, in the instance of the reporting this week around new findings that researchers say shows the rotation of Earth’s inner core is slowing ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the ...

Earth’s inner core has been slowing down for 14 years. It comes just weeks after another team of researchers suggested that the slight increase in the length of a day may be because Earth’s ...

The Earth’s magnetic field is why we are here today. It protects life from harmful radiation from the Sun and many other cosmic events. It is generated in the liquid outer core of our planet, but ...

Our planet's inner core, a solid iron ball bigger than Pluto, isn't just spinning – it's doing a wobbly routine, like a top losing its equilibrium, in a cycle that stretches nearly a decade.

A new study challenges the long-held assumption that Earth's inner core is hard, like a solid metal sphere. Instead, our planet's heart is likely much gooier than previously thought, "kind of like ...

We are basically showing that there may not have ever been a good reason to assume Mars' dynamo shut down early.' ...
