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

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 length of a day. Although these time changes are only estimated to be a matter of milliseconds a year, they accumulate over eons.

Earth’s core is transforming, which could affect the length of our 24-hour day, Earth’s magnetic field, and more

However, researchers from the University of Southern Carolina (USC) now say they discovered — almost by accident — that the Earth's inner core may be much more malleable. John

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the vibrations generated by earthquakes that pass through the planet. The speed and the direction of the seismic vibrations change depending on the density and the elasticity of the rocks.

New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.

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

A new study reveals that the Earth's inner core is undergoing a structural transformation. A new study by USC scientists, published in Nature Geoscience, reveals structural changes near the Earth's inner core,

New research suggests that Earth's inner core, long believed to be stable, may be undergoing structural changes, including a possible shift in shape, shedding light on the mysteries beneath the planet

A new study in Nature Geoscience reveals insights about the Earth’s core. While we often learn about the inner and outer cores, research is ongoing to under

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 inner core was widely thought of as a solid sphere.

A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing hidden dynamics deep within Earth.
