It wouldn’t be summer without the stretched out days. The dawns break early and the dusks come late, affording more time for lazy beach trips and long barbecues under the slow curve of the sun. But ...

Planet Earth will spin a little faster on three separate days this summer, starting today. This will technically result in shorter days, but the change will be so minuscule you won’t even notice.

Earth’s days are not always exactly 24 hours, and recent measurements show unusual fluctuations. Some days are getting ...

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 ...

A strange shift in Earth's rotation is making our days milliseconds shorter — and scientists are racing to understand why. The days are getting shorter and not just because summer is waning in 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 ...

The Earth is pretty good at keeping its pace. However, variations do happen. And on three separate days this summer—July 9, July 22, and August 5—the Earth will spin notably faster than usual. Of ...

Could the Earth experience 25 hour days in the future? A postdoctoral researcher in physics and astronomy at Michigan State University believes this to be the case. According to NASA, the moon has ...

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 ...
