Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

The Earth's internal layers including the mantle, outer core, and inner core. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really means has been up for ...

A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s innermost layer is changing shape. Scientists who just months ago ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

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 ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

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 ...

(CNN) — 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 ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance. The surface ...

Scientists who just months ago confirmed that Earth's inner core recently reversed its spin have a new revelation about our planet's deepest secrets — they identified changes to the inner core's shape ...
