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 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 ...

Earth's axis — the invisible line around which it spins — is bookended by the north and south poles. The axis tilts, and thus the pole shift, depending on how weight is distributed across Earth's ...

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.

Exoplanet Kepler 413-b orbits a close pair of orange and red dwarf stars once every 66 days. Not only does the planet's axis wobble like crazy, its orbit about the stars wobbles too. Credit: NASA, ESA ...

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 ...
