In recent weeks, astronomers have been monitoring strange, high-energy emissions from the corpse of a long-dead star some 30,000 light-years away. Within the emissions, they found something surprising: a powerful blast of radio waves that lasted mere milliseconds. The blast was, in fact, the brightest outburst ever seen from this star or any of its kind—immensely magnetic neutron stars known as magnetars.

The eruption of radio waves, though originating in our own galaxy, is remarkably similar to fast radio burst (FRBs)—fleeting, intensely bright radio flashes launched by as yet unidentified objects that, until now, had only been observed coming from other galaxies. Although it may raise just as many questions as it answers, this latest observation could solve at least one riddle surrounding the cosmic origin of FRBs.
