A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, ...

Deep below the surface, the Earth's inner core may have changed direction, new research suggests. Earth's inner core, a hot iron ball the size of Pluto, has stopped spinning faster than the planet's ...

The intriguing question of whether a plane can outrun Earth’s rotation has been a topic of recent aviation discussions. This ...

Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before 2020, the Earth never experienced a day shorter than the ...

Pumping groundwater appears to have a greater consequence than ever previously thought. But now—thanks to a study published in the journal Geophysical Research Letters— we can see that, in less than ...

On those three days, just over a millisecond is expected to be shaved off the standard 24-hour day. Of course, you're unlikely to notice such a miniscule difference in your day. But scientists who ...

Earth’s rotation dynamics are influenced by a range of internal and external factors, with Free Core Nutation (FCN) standing out as a key phenomenon. FCN arises from the slight misalignment between ...

Aren’t the summer days supposed to be longer and the winter days shorter? Since when have things gone in reverse for the summertime? Since now, maybe? Starting today? Okay, here’s what’s going on.

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 ...
