Earth, Inner Core

Earth’s Inner Core Is Slowing Down — and May Not Be Entirely Solid
The surprise discovery of earth’s core composition may debunk previous assumptions on the solidity of the planet.
Earth’s Core Is Changing Shape
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.
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
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.
Earth's inner core has shifted shape over two decades, scientists discover
Earth's inner core has changed shape over the past 20 years. A team of scientists studied the core's behavior to understand why its rotation slowed down
Scientists discover yet another change to Earth’s inner core: Its shape
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 and valleys.
Earth’s Solid Inner Core Is Changing Shape, New Study Finds
Researchers found evidence that the Earth's inner core is changing shape, suggesting unseen processes affecting its movement over time.

Earth's inner core isn't just slowing, it's also shape-shifting, study finds
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.
Earth’s Inner Core Is Changing Shape, Study Finds, Indicating Even More Dynamic Shifts Deep Within Our Planet
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
Earth’s Inner Core Is Changing Shape—Scientists Uncover a Deep Mystery at the Planet’s Center
The mysteries of Earth’s inner core have long been a topic of intrigue for scientists, with the planet’s central engine playing a key role in shaping our world. Recent research has unveiled an astonishing new discovery: the inner core is not only changing its rotation speed but is also undergoing subtle changes in its shape.
