In a nice piece of cross-pollination between disciplines, scientists have proposed a new method for measuring the Earth’s magnetic field strength using technology developed for ground-based observational astronomy. As it turns out, the laser guide stars astronomers use to sense the turbulence high up in the atmosphere can be used as cheap and efficient magnetometers.
