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 that sits some 3,000 miles (4,828 kilometers) below the surface.

“Later on, I’d realize I was staring at evidence the inner core is not solid.” The breakthrough came from comparing seismic recordings at two different locations in North America. The ...

“Later on, I’d realize I was staring at evidence the inner core is not solid.” Other than producing the Earth's magnetic field, Vidale admitted that what happens to the Earth's inner core ...

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

LOS ANGELES — 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 ...

Scientists have confirmed that the Moon has a solid inner core with a density similar to iron. The core's structure mirrors that of Earth's, with a fluid outer layer and solid inner core ...

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

"Later on, I'd realize I was staring at evidence the inner core is not solid." Further, the data showed that the inner core had been moving and not behaving like a solid ball of metal. Visualizing ...

“Later on, I’d realize I was staring at evidence the inner core is not solid.” The study used seismic waveform data - including 121 repeating earthquakes from 42 locations near Antarctica ...

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 ...

"Later on, I’d realize I was staring at evidence the inner core is not solid." Once Vidale's team improved the resolution technique, they found the seismic waveforms "represented additional ...
