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.

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.

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.

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the ...
