A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than ...

Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Previously, the inner core was believed to be a solid iron-nickel sphere surrounded by a liquid iron-nickel outer core, which generates Earth’s magnetic field. Vidale suggests that interactions with ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core ... cores consist primarily of iron and nickel. They're extremely ...

Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with ...

Data from NASA's InSight mission has revealed that Mars has a liquid core. Similar to Earth's core, the core of Mars is expected to be dominantly composed of molten iron metal. However ...

But a new study has found that its edges are softer than realized and actually changing shape as they press against the liquid iron and nickel in Earth’s outer core. “The molten outer core is ...
