THE ‘free nutation’ of the Earth is a motion of the Earth's instantaneous axis of rotation around its mean position. The poles (intersections of the axis with the Earth's surface) describe changing ...

Earth’s rotation dynamics are influenced by a range of internal and external factors, with Free Core Nutation (FCN) standing out as a key phenomenon. FCN arises from the slight misalignment between ...

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 ...

The results of the 250-day experiment were published in the renowned scientific journal Science Advances. Lead author Prof. K. Ulrich Schreiber from the TUM Institute of Engineering for Astronomical ...

image: An international team of scientists has managed for the first time to observe the 'nutation' of spins in magnetic materials (the oscillations of their axis during precession). The measured ...

About 1,800 miles beneath the surface, Earth’s internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. But the boundary between the ...
