Earth’s spin is not as steady as it looks. As ice melts and groundwater is pumped from deep aquifers to the surface, the planet’s mass is shifting, and with it the position of the rotational axis that ...

Earth’s spin is not as steady as it looks from the ground. As ice sheets melt and aquifers are drained, scientists now say the planet’s axis has shifted by more than 30 inches, a subtle but measurable ...

As Earth moves through space, it wobbles slightly. A team of researchers from the Technical University of Munich (TUM) and the University of Bonn has now succeeded in measuring these fluctuations in ...

A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect — in both shape and in rotation. Earth is not a perfect sphere.

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 ...
