Ever since its formation around 4.5 billion years ago, Earth's rotation has been gradually slowing down, and its days have gotten progressively longer as a result. While Earth's slowdown is not ...

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 ...

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 ...

If today feels like it's flying by, you can blame it on our spinning planet: A group of scientists tracking Earth's rotation predicts that the day will be a fraction of a second shorter than normal.

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 ...

The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond during the long days of summer. By Jacey Fortin This article was updated ...

The study highlights how longer days allowed cyanobacteria to photosynthesise more oxygen because their activity depends not just on sunlight but on the timing of their metabolic processes.

Earth is spinning faster this summer, making the days marginally shorter and attracting the attention of scientists and timekeepers. July 10 was the shortest day of the year so far, lasting 1.36 ...

Across the Northern Hemisphere, people are soaking up the long hours of summer sunlight, with no idea that they’re experiencing some of the shortest days since modern timekeeping began—by a ...

Suppose you could speed up Earth’s rotation so that a day was only half as long? What would happen? Well, for starters we’d have to make new clocks that only have hours 1 to 6 for am and pm. If you ...

Our planet may have had a recent change of heart. Earth’s inner core may have temporarily stopped rotating relative to the mantle and surface, researchers report in the January 23 Nature Geoscience.
