For nearly a billion years, Earth’s rotation stopped slowing down. Locked in a rare cosmic balance, the planet’s day remained ...

Physicists at NASA and Princeton generate electricity from the Earth's rotation: could wind energy be our energy source of ...

A billion years ago, days lasted 19 hours: the balance between the oceans, the atmosphere, and the Moon slowed down the Earth ...

Earth is spinning faster than ever, and the result is a shortening of the length of our days. Since 2020, each year has brought records for the shortest day ever, with Earth’s spin accelerating by ...

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 ...

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 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 ...

Brazil's Lula squares up to Trump, measles cases hit a 33-year high, and more Length: Long Speed: 1.0x If you’re the kind of person who gets a lot done, you’re grateful for every one of the 86,400 ...

(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 ...

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 ...

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 ...

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 ...
