When an earthquake is generated on the Earth’s surface, seismic waves ripple beneath the crust toward the other side of the globe, passing through the inner core in the process. When they reach ...

Earth’s inner core, a red-hot ball of iron 1,800 miles below our feet, stopped spinning recently, and it may now be reversing directions, according to an analysis of seismic activity. The ...

AUSTIN (KXAN) -A bit of news you didn’t expect, in a new study published this week in Nature Geoscience, scientists announced that they believe the Earth’s inner core has stopped spinning.

One explanation: The inner core is spinning, deflecting these waves. In the mid-1990s, Dr. Song was one of the first scientists to suggest that the inner core may be rotating at a different speed ...

That’s how he determined that the rotation has been decreasing since 2010. Prior to that, the core’s spin had been accelerating. The findings add to the mystique of the most inscrutable part ...

What if the Earth's core suddenly stopped spinning? Well, that would be wild! The magnetic field protecting us from harmful space radiation could weaken or even disappear, making Earth a target ...

The researchers said the inner core started reversing its spin after stopping and that this process repeats about every 35 years. The reversal last occurred in the early 1970s; the next could be ...

That liquid barrier between the core and the surface allows it to spin freely inside the interior space of the planet, almost like a three-dimensional ball bearing. RELATED: Swallowed by sinkholes ...

Update: As reported below, research from January 2023 indicated that the solid metal core of Earth might have reversed its spin, as part of a decades-long pattern of slowing down and speeding up.
