Scientists have uncovered surprising evidence that helium, a gas long thought to be chemically inert, may actually bond with ...

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

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

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

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...

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

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 ...

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

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 ...
