Their research led to an unexpected discovery: that inner core is not entirely solid. Scientists from the University of Southern California (USC) analyzed data from earthquakes and identified ...

Underneath the Earth’s crust we know there is a hot mantle and an even hotter outer and inner core, but now experts say we ...

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

By studying how seismic waves interact with the inner core, scientists have been able to make key observations about its composition and behavior. Vidale and his team studied 168 pairs of ...

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 ...

The inner core’s density is estimated at 7,822 ... As magnetic fields are generated by core convection, understanding the Moon’s core composition may explain why its field disappeared.

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

Earth's mysterious core is yet again generating headlines as scientists learn more about what lies way beneath our feet. Located 3,000 miles below the Earth’s surface, the inner core is anchored ...

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

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 ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges ...
