The Earth's inner core, long considered a solid and stable sphere, may be quite different. A recent study suggests that its surface is undergoing structural transformations, challenging

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.

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.

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 core is located below the middle layer called the mantle and the outer layer –or crust. It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer is made of liquid iron-nickel and is responsible for producing Earth’s magnetic field.

A new study has found evidence that the Earth's inner core may have changed shape. Far from taking place over geological timescales, the changes appear to have taken place within the last two decades.

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

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.
