Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly affect the ...

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

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

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

At the center of the Earth lies a hot, solid inner core composed predominantly of nickel and iron, with a radius of approximately 1,200 to 1,300 kilometers. This inner core is surrounded by a ...

Previously, the inner core was believed to be a solid iron-nickel sphere surrounded by a liquid iron-nickel outer core, which generates Earth’s magnetic field. Vidale suggests that interactions with ...

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

This metallic inner core, about 1,500 miles wide, was discovered in the 1930s. Both the inner and outer cores consist primarily of iron and nickel. They're extremely hot, with temperatures ranging ...

USC scientists have made a groundbreaking discovery about the nature of the Earth's enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing. The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found ...
