Astronomers say they have traced a mysterious pulsing in the Milky Way to a surprising source: a dead star locked in a dance with another star.

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,

For the first time, we have visual confirmation of a white dwarf/red dwarf system responsible for puzzling intermittent radio bleeps.
