Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

Earth's core might be layered like an onion, according to a new study that looked at the anomalous nature of waved in the ...

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 ...

Researchers have been aware for a few years that our inner core may not be the simple, solid ball of metal that we believed it to be. Seismic waves have illuminated that the core doesn’t appear to be ...

The diamond anvil cell used in this experiment. (A) Symmetric Diamond Anvil Cell, (B) Schematic diagram of a diamond anvil. The orange circle is the area corresponding to (C, D) (C) Image of the top ...

Scientists have discovered a new state of matter hidden right beneath our feet – and it could explain the most mysterious properties of our planet. A new study has found that Earth's innermost core ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

Seismologists have gleaned information about the inner core's motion by examining how waves from large earthquakes that ping this area behave. Variations between waves of similar strengths that passed ...
