It’s unlikely that a star is the culprit behind the odd signal

Astronomers have detected a strange, repeating radio signal near the centre of the Milky Way, and it’s unlike any other energy signature ever studied. The energy source is extremely finicky, appearing bright in the radio spectrum for weeks at a time and then completely vanishing within a day. This behaviour doesn’t quite fit the profile of any known type of celestial body, according to researchers, and thus may represent “a new class of objects being discovered through radio imaging”.
