The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...
A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.
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.
The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...
Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...
The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...
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 ...
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 surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron ...
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 ...
Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it ...
