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

Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at ...

The Earth is made up of different layers. The outermost is the crust ... Then there is the outer core, made of liquid metal, and the inner core, a solid ball of metal. At least, that is what ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

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 ...

Scientists now know how to drill deep enough to tap into an energy supply that would power the world for more than 20 million ...

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 ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

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 ...

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 ...

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 ...
