In the past three years, astronomers have discovered a mysterious new type of radio source. We call these long-period transients.

Astronomers have traced a starnge blast of radiowaves that repeats every 2 hours back to a dead star white dwarf magnetically slamming its stellar companion.

He believes astronomers could now search for other signals from binary systems, possibly involving neutron stars or magnetars. A Decade-Long Search. The signals were first detecte

Astronomers have spotted a red dwarf star in a system that is almost certainly the source of a radio signal that, for a while, repeated once every 125 minutes. Moreover, there’s evidence of a white dwarf companion.

Earth has been at the receiving end of mysterious radio emissions every two hours. After more than a decade, the source of these signals has finally been identified, nearby the Big Dipper. A new research paper published in Nature Astronomy points to a red dwarf and white dwarf star,
