A Mysterious Signal From Space Has Finally Been Decoded, Astronomers Say

For years, astronomers have been chasing a strange kind of cosmic signal that did not fit neatly into the usual explanations. It was powerful, repetitive, and slow enough to make researchers question whether the known suspects in deep-space radio astronomy could really be responsible.

Now, a new finding has pointed to a surprising source: not a single exotic object spinning alone in space, but two stars locked in a tight and violent relationship. The system, known as ASKAP J1745−5051, could help explain one of the most puzzling classes of radio signals detected in our galaxy.
