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 iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

If the core froze relatively recently, the current thermal state at the inner core–outer core boundary indicates how much the combined core might have been below its melting point when the inner core ...

The new study provides unambiguous evidence that the inner core began to decrease its speed around 2010, moving slower than the Earth's surface. USC scientists have proven that the Earth's inner core ...

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 ...

An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models. Read the paper: Seismic detection of a ...

The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

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 ...

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 ...

Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many years. For decades, scientists have known the inner core is solid thanks to ...
