It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied scientists for generations. It sits over 3,000 miles below the surface, smaller ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

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.

Scientists now know how to drill deep enough to tap into an energy supply that would power the world for more than 20 million years if we capture just 0.1 percent of it.

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

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 ...

New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls ...

Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new piece of the puzzle has now emerged with the discovery that they have ...

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 ...

The leading explanation for all of these mysteries is known as the giant impact hypothesis. According to this story, when the ...
