Like a spinning top slowing down, Earths axis wobbles, scribing out a circle on the night sky that currently points very close to the Pole Star in the northern hemisphere. This wobble is driven by the shape of the Earth and for decades, this wobble has been tracked by a network of radio telescopes. A team of astronomers have measured this wobble to a level ...
