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.

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 ...

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 ...

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 ...

Humans are responsible for some of the wobble in Earth's spin. Since 1899, the Earth's axis of spin has shifted about 34 feet (10.5 meters). Now, research quantifies the reasons why and finds that a ...

According to Phys Org, the study shows that unexpectedly for any close planetary system body other than the Earth, a chandler wobble has been identified on Mars. The Chandler wobble is characterized ...

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 ...

An in-depth study conducted by NASA found that humans are responsible for the increasing wobble detected as Earth spins on its axis. When you think of Earth you may think of an exact sphere, but Earth ...
