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.

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.

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 ...

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

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

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

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 ...

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.

LOS ANGELES — USC scientists have made a groundbreaking discovery about the nature of the Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and ...

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 ...

The Earth is continuously changing, with constant transformations occurring both on its surface and within its core. The movement of tectonic plates, climate shifts, and the drifting of the ...
