If the atmosphere were not dragged with our planet, you could utilize the insane relative wind speeds to decrease flight time ...

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 ...

If you're seated while reading these words — as I am writing them — you're most likely convinced that you and the room around ...

The Earth's core is slowing down and now spinning in the opposite direction. What does this mean? The rotation of the Earth's core has changed, and scientists are wondering what could be causing it.

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 ...

Earth’s rotation is speeding up. This summer, our planet will spin faster than usual, creating the shortest day since records began. Though we cannot sense these changes, they show the forces that ...

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 ...

Day length was as short as 19 hours in Earth's past because the Moon was closer, finds new research. Earth may currently be spinning faster, but a day on our planet lasts 24 hours largely because of ...

Scientists have debated for years about what's going on with Earth's inner core. A new study offers compelling evidence that the inner core reversed direction and is slowing down. The shift happened ...

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 ...
