For the first time, magnetic fields have been detected in three massive, hot stars in our neighboring galaxies, the Large and Small Magellanic Clouds. While magnetic massive stars have already been detected in our own galaxy, the discovery of magnetism in the Magellanic Clouds is especially important because these galaxies have a strong population of young massive stars. This provides a unique opportunity to study actively forming stars and the upper limit to the mass that a star can have and remain stable.
