Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars. Scientists call this difference crucial to ...

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 ...

If you haven’t accomplished as much this summer as you had hoped to, you can blame forces far beyond your control: a few of these dog days, by one measure, are among the shortest you’ve ever lived ...

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 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 ...

Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the ...

One day in the next couple of years, everyone in the world will lose a second of their time. Exactly when that will happen is being influenced by humans, according to a new study, as melting polar ice ...

So called human-built megastructures may actually be slowing down the Earth's rotation. This isn't exactly new information, but it has recently been making the rounds again, especially on social media ...

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 ...

As rising global temperatures melt Earth’s polar ice sheets, the shifting water is creating such a huge redistribution of our planet’s mass that its rotation speed is dropping. This unusual result of ...
