When these stars dance, they make their own music. Astronomers have tracked down the source of a mysterious radio signal from deep space repeating every two hours. Stunningly, it's a pair of stars in such a tight orbit that their magnetic fields regularly bump into each other — and it's this bodily percussion which is blasting out the radio emissions we're picking up on Earth.

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

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

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,
