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'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 that sits some 3,000 miles (4,828 kilometers) below the surface.

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

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 have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic ...

A recent study revealed that Earth’s inner core is slowing down, prompting scientists to investigate further. Their research led to an unexpected discovery: that inner core is not entirely solid.
