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 Earth is in a constant state of flux, and changes are constant on its surface and deep within its core. The shifting tectonic plates, climate variations, and even the movement of the magnetic ...

Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic ...

The work was done by Haruki Takezawa and Kei Hirose at the University of Tokyo and colleagues, who suggest that Earth’s core could host a vast reservoir of primordial helium-3 – reshaping our ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

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 ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...

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 ...

Its loss from magma suggests that the planet has a deep reservoir of primordial helium, and the new compounds suggest that Earth’s iron-rich core could hold some of that helium. But the team ...
