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.

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

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.

By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner ...

Data from NASA's InSight mission has revealed that Mars has a liquid core. Similar to Earth's core, the core of Mars is expected to be dominantly composed of molten iron metal. However ...

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

New research reveals that the Moon's core has a density similar to that of iron. This discovery may settle long-standing ...

Barnard's Star is a small, dim star of the type that astronomers call red dwarfs. Consequently, even though it is one of the ...

Scientists have raised concerns that the Earth's inner ... of nickel and iron, with a radius of approximately 1,200 to 1,300 kilometers. This inner core is surrounded by a liquid outer shell ...

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 ...
