NPR's Ayesha Rascoe talks to John Vidale, professor of earth sciences at the University of Southern California, about new research suggesting the rotation of Earth's inner core may be slowing down.

The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

Earth’s rotation is no longer matching the tidy 24-hour day that our technology assumes. Since 2020, each day has been ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

Meltwater from the polar ice caps, combined with the shifting spin of Earth's core, is messing with the Earth's rotation to the point that we might need to adjust for a "negative leap second." The ...

The rotation of Earth's inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores. The solid inner ...

Earth spun just a bit faster than usual on July 9 and is expected to do so again on July 22 and Aug. 5, according to the website TimeAndDate. Over a millisecond was reportedly shaved off the clock on ...

(Photo by Planet Observer/Universal Images Group via Getty Images) The standard day on Earth consists of 24 hours, which is 1,440 minutes and 86,400 seconds. However, shorter days are ahead in the ...

Earlier this month, the Earth spun just a bit faster than usual on July 9 and is expected to do so again on July 22 and Aug. 5, according to the website TimeAndDate. Over a millisecond was reportedly ...

WASHINGTON — Wednesday will be slightly shorter than usual, but you probably won't notice the difference even if you're watching the clock closely. Earth is expected to complete a full rotation on ...

Decades worth of seismic data confirms the rotation of Earth's inner core is moving slower than the planet's surface. When you purchase through links on our site, we may earn an affiliate commission.
