Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

In a paper published in Earth and Planetary Physics, a scientific team presents a good correlation between temporal ...

Not only is Earth's inner core spinning and growing, but it's also changing shape, according to new research. Our planet's ...

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 ...

Something strange is happening at Earth’s center. Decades of earthquake data show that Earth’s inner core has been rotating slower than its mantle and surface since around 2010, researchers report ...

Earth's core isn't exactly aligned with its mantle, which results in a cyclical wobble, new research finds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

Earth’s magnetic field nearly collapsed long ago. What saved it explains why life survived and why the planet remains ...

Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past.

By tracking seismic waves from earthquakes that have passed through the Earth's inner core along similar paths since 1964, the authors of the 2023 study found that the spin followed a 70-year cycle.
