Earth, inner core

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 changing shape? Scientists reveal it may have 'deformed by over 100 meters'
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
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 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 Is Mysteriously Changing Shape, Study Reveals
A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation speed – it also appears to change in shape, with subtle variations appearing in the way acoustic waves propagate through the planetary center.
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.
