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.

Astronomers have finally traced mysterious radio pulses in the Milky Way to a unique cosmic duo—a red dwarf and a white dwarf orbiting each other every two hours. This discovery challenges previous assumptions that only neutron stars produce such signals.

An international team of astronomers led by scientists from the Netherlands has shown that a white dwarf and a red dwarf orbiting each other every two hours are emitting radio pulses. Thanks to observations with several telescopes,
