They found an odd ring around the outer core's equator, where earthquake waves move more slowly than in surrounding regions. Earth's outer core is made up of liquid iron and nickel and surrounds ...

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

A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that the moon has a solid inner core, similar to Earth’s, composed of iron with a ...

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 ...

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

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 ...

Skip the crunches! Try these 7 standing core exercises for a stronger, sculpted midsection—no floor work required.

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 ...

"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.
