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 Earth’s axis using a completely new method—until now, possible only through complex radio astronomy. The team used the high-precision ring laser at TUM’s geodetic observatory in Wettzell, Bavaria.
