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, ...

The Earth's rotation is about to accelerate significantly. According to scientists, July 9, July 22, and August 5 of this year will be some of the shortest days in recent memory as a result, slicing ...

The Mechanics of Earth's Spin Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 ...

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 ...

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Warming across the Arctic is not only melting ice but it’s also causing another issue: Changing the speed at which the earth rotates, according to Duncan Agnew, a geophysicist with the Scripps ...

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 ...

Scientists anticipate that a “negative leap second” might soon be required, shortening our days by a second, due to polar ice melting. Historically, Earth has seen its rotation decelerate due to tidal ...

We’ve probably all had a few conversations with people who hold eccentric scientific ideas, and most of the time they yield ...

Climate change is causing the ice masses in Greenland and Antarctica to melt. Water from the polar regions is flowing into the world’s oceans –and especially into the equatorial region. “This means ...

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 rotation ...
