The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Deep within Earth’s core, scientists are uncovering signs of a hidden structure that challenges long-standing models of the planet’s interior.

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

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 ...

The surface of the Earth's inner core may be changing, as shown by a new study by USC scientists that detected structural changes near the planet's center, published in Nature Geoscience. The changes ...

Researchers have found evidence for a distinct 'innermost inner core' at the center of Earth, challenging the long-held four-layer model of the planet’s structure. Seismic wave analysis reveals a ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. New research suggests that Earth’s inner core has been ...

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 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. The surface ...
