Big dams don’t just redraw maps — at extreme scale, they can nudge Earth’s rotation by a hair. Here’s what NASA-backed ...

Key Takeaways on the Speed of Earth's Rotation The speed of Earth's rotation is about 1,000 miles per hour relative to its axis. Your exact speed of rotation due to Earth's spin depends on your ...

University of Reading’s Dr James O’Donoghue explains why no day is ever really the same – horologically speaking.

Since 2020, Earth has continued breaking its speed records. The shortest day ever recorded was on July 5, 2024, when Earth’s rotation was completed 1.66 milliseconds faster than usual.

In a rare and unprecedented move, scientists and world timekeepers are considering reducing one second from Coordinated ...

To find out how fast the Earth is spinning at all, you need to find a reference frame in which, ideally, nothing is moving.

A strange shift in Earth's rotation is making our days milliseconds shorter — and scientists are racing to understand why.

Zotov predicts Earth’s rotation may soon decelerate once again. If he’s right, this sudden speeding-up could prove to be just ...

Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they ...

Recent research has revealed that Earth’s core is undergoing a slowdown in its rotation, a phenomenon that has piqued the ...
