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 ...

For the first time, researchers at ETH Zurich have been able to fully explain the various causes of long-term polar motion in the most comprehensive modeling to date, using AI methods. Their model and ...

Earth’s Rotation Day 2026, observed on January 8, highlights how Earth’s constant rotation shapes day and night, climate, ...

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 ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

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 ...

Time on Earth Is Changing: How the Planet’s Spin Is Gradually Slowing (Image: Canva) Scientists say Earth’s familiar 24-hour day is slowly changing. The shift is real, measurable, and already underway ...

One day in the next couple of years, everyone in the world will lose a second of their time. Exactly when that will happen is being influenced by humans, according to a new study, as melting polar ice ...

Polar ice melt driven by climate change is affecting Earth's rotation, according to new research. We may have to adjust timekeeping by "skipping" a second in 2029. A human-driven change in the Earth's ...

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 ...
