Dead star's pulses reveal secrets of its sun-like companion

A mysterious radio signal repeating every eight minutes has been traced to a rare star system about 5,000 light‑years away, revealing new clues about a puzzling class of deep‑space radio emissions. Astronomers attribute the pulses to a white dwarf paired with a sun‑like star, offering insights into how such binary systems generate and modulate these signals. The discovery could help explain similar phenomena observed elsewhere in the galaxy.
