Astronomers discovered an unusual radio signal with a 36-minute period. It sent pulses for only eight days, then vanished. Its radio waves oscillated strictly in one plane, and that plane gracefully rotated. Such 'beacons' likely flare up frequently in the Galaxy, but are hard to catch. Unraveling t

The system ASKAP J1745−5051 is a close binary where a magnetic white dwarf strips material from a red dwarf every 1.37 hours. The resulting radio bursts are so powerful that their brightness temperature exceeds 10^12 K, requiring a coherent emission mechanism — a cosmic analog of a laser. Spectrosco
