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

As if it's not already hard enough to find the time to do everything you need to do in a day, now you're about to lose another whole millisecond or more. In fact, experts say Tuesday, July 22, could ...

We live on a spinning planet. Depending on latitude your individual speed varies from 0 mph at the poles to 1,040 mph (1,674 kph) at the equator. Here at 47 degrees north I'm madly spinning eastward ...

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 ...

If you've felt like summer days are flying by, you're not wrong—at least not scientifically. Experts have observed that Earth's rotation is speeding up, making some days slightly shorter than the ...

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 ...

Climate change is starting to alter how humans keep time. An analysis 1 published in Nature on 27 March has predicted that melting ice caps are slowing Earth’s rotation to such an extent that the next ...

NPR's Ayesha Rascoe talks to John Vidale, professor of earth sciences at the University of Southern California, about new research suggesting the rotation of Earth's inner core may be slowing down.

Researchers looked through historical documents dating back to the fourth century to find total solar eclipses. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

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 ...

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 ...

Decades worth of seismic data confirms the rotation of Earth's inner core is moving slower than the planet's surface. When you purchase through links on our site, we may earn an affiliate commission.
