Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

Experts warn that "something" in the core of the Earth is causing the magnetic pole to shift. North Pole is shifting toward Siberia and raising concern ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

Tectonic plates float on the semi-solid mantle, which moves very slowly as a result of convection currents driven by heat energy from the hot core. The outer core is liquid iron and nickel and ...

Then there is the outer core, made of liquid metal, and the inner core, a solid ball of metal. At least, that is what scientists thought. New research published in the journal Nature Geoscience ...

"The transition from the innermost (solid) ball to the outer shell of the inner core (also solid shell) seems rather gradational than sharp," explains study coauthor Dr. Thanh-Son Phạm.

The inner core spins independently from the liquid outer core and the rest of the planet. Without this motion, Earth would die and become more like barren Mars, which lost its magnetic field ...
