The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been ...

The liquid outer core envelops the solid inner core. The liquid outer core, which extends to 1,795 miles above the solid core, Koper says, produces a protective field of magnetic energy.

Earth's inner core is a solid ball of mostly iron and nickel.Measuring about 1,520 miles (2,440 kilometers), this inner core spins inside the outer core, an ocean of molten iron and nickel about ...

These dense solid droplets descend towards the center and develop an inner Fe-Ni core, which leaves behind a S-enriched liquid OC [outer core]," the team explains in their discussion.

The magnetic field and the liquid outer core are further stabilized by the more solid inner section. The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth.

The Earth's inner core is an enduring mystery: Here's how researchers are starting to solve it. Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball ...

Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature Communications. Data from NASA's InSight mission has revealed that ...

The researchers’ results indicated that Mars most likely has a completely liquid core, unlike Earth’s combination of a liquid outer core and solid inner core. Published - April 29, 2023 09:15 ...

What's more, there may be swirls of liquid iron trapped inside the solid core, study senior author Keith Koper, a seismologist at the University of Utah, said in a statement. "A long time ago the ...
