Twenty Years of exoplanet research has seen incredible advances in detecting planets orbiting distant stars, as well as their size, orbit period, orbit distance, and even atmospheric composition.  But the next step in understanding exoplanets is to learn about their magnetic fields. We know that many exoplanets should have magnetic fields.  It makes sense, since nearly every world in our own solar system has some sort of magnetism.  But for the first time, an international team of Astronomers, led by Kristina Kislyakova of the Space Research Institute of the Austrian Academy of Sciences, have discovered a way to detect magnetic fields...
