For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

The Mysterious Inner Core Understanding Earth's internal structure may help understand the significance of this finding. Below the crust, where life exists, the planet is made up of layers-the ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

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

Earth's diameter is about 7,900 miles. The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of magma and a solid inner core.

This inner core is surrounded by a liquid outer shell of the same composition, enclosed by the mantle—a thick layer that begins about 30 kilometers beneath the Earth's surface and extends to a ...

the time it takes for seismic waves to travel through the Earth's different layers was observed and measured with an algorithm whose function was to match various inner core models. In this way ...

The Earth's inner core, long considered a solid and stable sphere ... However, new data shows that its outer layer may be more malleable than expected. This discovery is based on the analysis of ...

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...
