Planet Earth is spinning a little faster today — resulting in one of the shortest days of the year. But the change will be so minuscule you won’t even notice. We’re talking even less time than the ...

Earth's rotation is subtly accelerating, and scientists are intently tracking the trend. Usually, our planet takes 24 hours, or 86,400 seconds, to finish one complete spin. However, on July 9, 2025, ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its momentum goes to the Moon. To put it another way, as the Moon's orbital momentum ...

Does it feel like there's not enough time in the day for everything? Well, that could be because some upcoming days are actually getting shorter. In fact, today might just be the shortest day you'll ...

As if it's not already hard enough to find the time to do everything you need to do in a day, now you're about to lose another whole millisecond or more. In fact, experts say Tuesday, July 22, could ...

As just one of all the living creatures on Earth, you're along for the ride as our planet constantly moves in two major ways.

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, ...

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.

As the polar ice caps melt, the Earth actually slows down, California scientists say. Less ice at the Earth's poles and more water weight spread around to other places are leading to the planet ...

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...
