It is true that the outer core generates electrical currents that sustain the planet’s magnetic field, but Vidale says shifts in the Texas-size inner core are too minuscule to have an impact.

They found that the inner core once spun faster than Earth itself. But beginning around 2010, the solid inner core’s spin slowed. It’s now revolving backward, relative to the rest of the planet.

The 2003 disaster film "The Core" imagines that the rotation of Earth's center has stalled, damaging the magnetic field that envelops the planet — and triggering a violent lightning storm that ...

One promising model proposed in 2023 described an inner core that in the past had spun faster than Earth itself, but was now spinning slower. For a while, the scientists reported, the core’s ...

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.

This metallic inner core, about 1,500 miles wide, was discovered in the 1930s. Both the inner and outer cores consist primarily of iron and nickel.

Scientists have discovered that our planet's core has been rotating at a slower rate for nearly 15 years -- and it could mean longer days for some. The wheel of time isn't turning like it used to.

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 ...
