The rotation of Earth's inner core began to slow down more than a decade ago, altering the length of our days by fractions of a second. Researchers from the University of Southern California (USC) ...

The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth's days — though the ...

Deep inside Earth, researchers see signs that the solid inner core may be arranged in multiple chemical layers far below.

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

For decades, scientists have tried to understand how Earth’s inner core operates compared with the rest of the planet. Now, a ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

The inner core of our planet has started spinning slower and slower, new research has revealed Compared to the speed of the Earth's surface, the inner core was previously thought to rotate faster.

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

Though Earth's innermost core is solid, new research suggests that it hosts a lot of variation. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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 surface ...

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 ...
