This is because the internal solar environment plays an important role in determining the weather in space and also the Earth ...

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

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.

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 ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

Earth's mysterious core is yet again generating headlines as scientists learn more about what lies way beneath our feet. Located 3,000 miles below the Earth’s surface, the inner core is anchored ...

The surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron helide means we may have misunderstood the chemistry making up the ...

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.
