Earth, inner core

Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found that its edges are softer than realized and actually changing shape.
Researchers Uncover Mysterious Structural Changes in Earth’s Inner Core
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,
Scientists discover Earth's inner core isn't just slowing down — it's also changing shape
The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.
Researchers announce major discovery about Earth’s inner core
Researchers at the University of Southern California say they’ve unraveled the mystery of why Earth’s inner core has been slowing, gradually altering the length of a day. For decades, scientists assumed Earth’s moon-sized core was made of solid iron and nickel and moved in lock with the planet’s surface.
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 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.
Earth’s inner core is deforming—here’s what we know
In a nutshell Scientists have discovered that Earth’s inner core isn’t just changing its rotation speed – it’s actually deforming at its surface. This is the first time such structural changes have been observed on human timescales.
Earth’s inner core is not solid, it is 'shape-shifting' - time for textbooks to be rewritten
New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.
