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 ...

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

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.

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 discovery changes our understanding of helium, a gas considered inert, by revealing its ability to bond with iron ...

A Slowing Core and Its Effects In June 2024, USC scientists published a study showing that Earth’s inner core has been slowing since 2010. This deceleration slightly affects the planet’s rotation, ...

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 ...

In other words, if scientists can show that Earth's core contains a lot of helium-3, it will strongly suggest that the planet formed quickly, settling a long-standing debate about the birth of the ...

The findings confirm that helium could stay locked in Earth's solid inner core for a long time ... there is more work to be done to show that the same interpretation can be applied to the liquid ...
