On July 9, 2025, scientists at the International Earth Rotation and Reference Systems Service (IERS) reported that the Earth ...

But with atomic clocks tracking the Earth’s rotational speed so closely that once every year and a half or so, the ...

The Earth rotates at about 1,670 kilometers per hour at the equator, yet we experience no sense of motion. But how is this ...

As Earth spins faster than it has in decades, atomic clocks are catching the difference, and shorter days are on the horizon.

Atomic clocks — among the most precise instruments humans have ever built — have been keeping track of Earth’s spin since the ...

Earth is set to break records with July 9 marking the shortest day ever recorded, shaving off 1.3–1.5 milliseconds due to ...

Scientists expect a specific day in July to be the shortest day of 2025 so far, running just over a millisecond faster than ...

Well according to astronomers, last night was a few milliseconds 1.3 ms shorter to be precise and there are more days this ...

Experts have observed that Earth's rotation is speeding up, making some days slightly shorter than the standard 24 hours.

Clock time is also getting shorter, kind of. Broadly speaking, Earth takes roughly 24 hours to spin around on its axis. Ocean ...

A solar day should last exactly 86,400 seconds, or 24 hours. The scientific community is concerned about how the Earth's rotation is accelerating. In this regard, astrophysicist Gr ...
