A neutron star with a magnetic field a quadrillion times stronger than Earth's suddenly ejects a plasma blob. If the cloud is dense, it flashes in X-rays; if it's thin, it produces a mysterious radio pulse from a distant galaxy.
🎯 A magnetar flare can outshine all the stars in a galaxy combined in just a tenth of a second.
🎬 Like in the movie 'Contact,' fast radio bursts were initially mistaken for alien signals.
