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.

That day, a Wednesday, was 1.59 milliseconds shorter than ever before. It happened because the Earth isn't perfectly spherical and can "wobble" on its axis. The Earth had its shortest ever day this ...

Wednesday, June 29, 2022, was slightly shorter than any other day by a mere 1.59 milliseconds, all due to a slight "wobble" of the Earth, according to scientists. An average day is 86,400 seconds, or ...

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 ...

Scientists in Germany have used a highly sensitive underground ring laser to track Earth’s axial wobble without relying on telescopes, satellites, or external reference signals. The researchers from ...

Last month I wrote about why the Tropic of Cancer and the Tropic of Capricorn are related to the 23.5 degree tilt of the Earth’s axis: The Sun’s furthest point north or south, called the solstice, is ...

In 2019, scientists detected a strange wobble deep below the Earth’s surface that oscillates roughly every 8.5 years. Now, by mapping minute changes in the Earth’s rotation, the team has come up with ...
