New research by Yale University scientists suggests an explanation for the amount of iron in the Earth’s largest interior layer, the mantle: migrating “iron-rich blobs” generated by chemical ...

New experiments have shown that the core of Mars formed much faster than Earth's core, thanks to molten iron and nickel sulfides seeping down through solid rock and into the center of the Red ...

A layer of molten rock above the core led to confusing seismic signals.

Today, Earth’s core is actually two pieces. There’s an outer layer of molten metal about 1,795 miles thick. Inside that layer of molten metal lies a solid sphere of iron and nickel: the inner ...

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 ...

An international team re-created molten rock conditions deep within the Earth and measured the spin states of iron atoms within that rock melt. An iron atom's spin state drives its ...

Inside the belly of planet Earth, a giant solid ball of metal is surrounded by a swooshing layer of liquid iron and nickel, making up the two innermost stages of Earth’s geological layers. These ...

Earth’s protoplanets are often thought to have had the mass of Mars or smaller 6. a, Young et al. 1 propose that one protoplanet was 0.2–0.3 Earth masses and had sufficient gravity to retain a ...

A new study suggests that Earth's true core could be a ball of iron-nickel that scientists hadn't uncovered yet.

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 ...
