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 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 ...

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

Where the Earth’s core meets the mantle ... and the way their speed varies in different parts of the planet and sometimes bounces off the boundaries. One relatively early discovery was that ...

The Earth's interior is composed of four layers ... in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe ...

Now, a groundbreaking study published in Physical Review Lettersoffers a surprising explanation: Earth’s core may contain ...

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.

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 ...
