It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied ...

Scientists have long theorized that primordial helium—helium-3, an isotope formed before Earth’s creation—exists in the planet’s core. Related Stories ・Earth’s inner core is far less ...

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 core of the Earth is undergoing surprise structural changes, researchers believe. A new study has seen scientists unexpectedly find that the inner core of our planet is changing its physical ...

This primordial element was already known to exist inside Earth. Each year, about 4.4 pounds (2 kilograms) of helium-3 leaks out of mid-ocean ridges where the crust is pulling apart and out of ...

Understanding how the Earth's core works is important to know the working of the magnetic field that protects the planet and whether that could weaken or stop. The inside of our planet is an ...

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 ...

Inside the Earth’s iron and nickel core, it’s 9,392 degrees Fahrenheit, about five times hotter than the lava that spews out of volcanoes. The heat dissipates outward through the layers of our ...

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 ...
