Millimeter deviations from the expected wobble of the Earth's axis are giving geophysicists clues to what happens 1,800 miles underground, at the boundary between the Earth's mantle and its iron core.

If you feel like there's less time in the day, you're correct. Scientists recorded the shortest day on Earth since the invention of the atomic clock. Our planet's rotation measured in at 1.59 ...

Recently, the results of a 250-day experiment to refine a particular motion of our planet were published in the journal Science Advances. Lead author K. Ulrich Schreiber from the TUM Institute of ...

The Earth had its shortest ever day on June 29, 2022, a scientist said. That day, a Wednesday, was 1.59 milliseconds shorter than ever before. It happened because the Earth isn't perfectly spherical ...

A 250-day experiment using a ring laser achieved unprecedented accuracy in measuring Earth's axial wobble (nutation and precession), surpassing previous gyroscope and ring laser technologies by a ...
