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

Planet Earth will spin a little faster on three separate days this summer, starting today. This will technically result in ...

From all four triangles, the full 3D rotation vector of the Earth can be reconstructed. Although the long-term stability is still not comparable to VLBI, ROMY can provide complementary real-time ...

As for when this three-day event will happen, there are three days this summer when the moon will be around its furthest ...

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

Earth spun a little faster than usual, enough to make the day about 1.3 to 1.6 milliseconds shorter than the standard 24 hours.That may not sound like much, but it was the shortest day since modern ...

Thanks to atomic clocks (and all the worldly forces that influence them), scientists know that Earth's rotation has begun to ...

Earth completed its normal 24-hour rotation 1.59 milliseconds fast on June 29, breaking the record for the shortest day in modern history. NASA Sign up for CNN’s Wonder Theory science newsletter.

For a while, the scientists reported, the core's rotation matched Earth's spin. Then it slowed even more, until the core was moving backward relative to the fluid layers around it.

Planet Earth will spin a little faster on three separate days this summer, starting on July 9. This will technically result ...

While the Earth’s rotation changes over cosmic timescales, it also fluctuates on daily ones. We all know that a day lasts 24 hours, or 86,400 seconds, but that’s not perfectly accurate.
