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 ...

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 ...

Thanks to a new study proves that Earth's inner core since 2010 has been rotating more slowly than usual. This intriguing ...

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

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 ...

A University of Minnesota professor said the Earth’s inner core hasn’t stopped but has slowed down in response to a CNN article published Jan. 26 titled “Earth’s Core May Have Stopped Turning and ...

Deep within Earth 's fiery belly, beneath layers of molten rock, a peculiar jig is underway. Our planet's inner core, a solid iron ball bigger than Pluto, isn't just spinning – it's doing a ...

Caption A cut-away of Earth's interior shows the solid iron inner core (red) slowly growing by freezing of the liquid iron outer core (orange). Seismic waves travel through the Earth's inner core ...

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 ...

Is there something strange and alien confined deep inside the Earth? Is it trying to break free and escape into the heavens?

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 ...

Earth’s inner core is a hot, solid ball—about 20% of Earth’s radius—made of an iron alloy. The planet’s outer core, beneath the rocky mantle, is a colder, liquid metal. Geophysics models explain that, ...
