Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer—like the ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

(CNN) — Scientists who just months ago confirmed that Earth’s inner core recently reversed its spin have a new revelation about our planet’s deepest secrets — they identified changes to the inner core ...

The scientists’ prior work on core rotation helped them interpret variations in the height of seismic waves, defining them as indicators of changes to the surface of the inner core, said Dr. John ...
