For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface. However ...

The inner core, located about 3,100 miles (5,000 km) below the surface, is traditionally described as a solid ball of iron and nickel. However, new data shows that its outer layer may be more ...

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 ...

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.

Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic ...

In June 2024, USC scientists published a study showing that Earth’s inner core has been slowing since 2010. This deceleration slightly affects the planet’s rotation, leading to marginally longer days.

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.

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

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.

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...
