The mysteries of Earth’s inner core have long been a topic of intrigue for scientists, with the planet’s central engine playing a key role in shaping our world. Recent research has unveiled an ...

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 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.

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 ...

Finding out that helium can bond with iron in extreme conditions may mean there is an entire reservoir of helium in our core. Earth appears to be a chill blue planet, but deep down, it’s really ...

To gig deep into the Earth's mysteries isn't just science fiction. The video highlights one of humanity's boldest attempts at ...

According to a recent study, the Earth's inner core, that is a solid ball of iron and nickel, is slowing down in relation to the planet's surface. The same was confirmed by USC scientists ...

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.

They used a laser-heated diamond anvil cell to find this, and the discovery suggests there could be huge amounts of helium in the Earth's core. This could challenge long-standing ideas about the ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
