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 ...
Strange variations across different measurements of the planet's surface have revealed periodic oscillations deep in Earth's heart. By studying minute changes in the length of Earth's day and the ...

A more precise measure of Earth's wobble
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 ...
