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, ...

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 ...

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 ...

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 ...

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 ...

New research reveals that carbon made it possible for Earth’s molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth’s deep interior — and ...

It is known that the surface temperature of the inner core of the center of the earth, which is 96% composed of iron as a solid, is higher than the surface temperature of the sun. The reason why the ...
