This inner core has intrigued researchers since its discovery by Danish seismologist Inge Lehmann in 1936, and how it moves — ...

New research has confirmed that Earth's inner core, a solid metal ball spinning independently within the planet, has significantly slowed down. Published in the journal Nature, these findings ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, ...

Deeper still is the Earth's hot, liquid iron-nickel outer core, larger than the moon. Like a peach pit, at the very center is the inner core, some 1,500 miles across. The ways seismic waves reflect ...

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.

Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe it contains sulfur and nickel, plus smaller amounts of other elements.

Mercury ' s inner core is solid and about the same size as Earth ' s inner core, a new study using observations from NASA's MESSENGER mission has indicated. Mercury is the smallest planet in our ...

Yan said that the one-sided magnetic field could arise if Mars' inner core was liquid. "The logic here is that with no solid inner core, it's much easier to produce hemispheric (one-sided ...

Researchers found that Mars could have produced a one-sided magnetic field with a fully molten core, rather than the traditional, Earth-like solid inner core setup. Like Earth, Mars once had a ...
