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 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 ...

Earth is spinning faster than ever, and the result is a shortening of the length of our days. Since 2020, each year has brought records for the shortest day ever, with Earth’s spin accelerating by ...

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 ...

The Earth we live on looks like a beautiful blue sphere when viewed from outer space. However, from the strict perspective of geodesy and geophysics, the Earth is not a perfect 'true sphere.' In ...

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 ...

For the first time, researchers at ETH Zurich have been able to fully explain the various causes of long-term polar motion in the most comprehensive modeling to date, using AI methods. Their model and ...

We’ve probably all had a few conversations with people who hold eccentric scientific ideas, and most of the time they yield nothing more than frustration and perhaps a headache. In [Bertrand Selva]’s ...

Meltwater from the polar ice caps, combined with the shifting spin of Earth's core, is messing with the Earth's rotation to the point that we might need to adjust for a "negative leap second." The ...
