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.

Astronomers detected constant stream of radio pulses emitted from across the galaxy. Team now finds the pulses are from a white dwarf and red dwarf binary. The stars’ orbit is so tight that their magnetic fields interact,

Astronomers have figured out where a stream of long radio bursts is coming from, and its origin is unprecedented. Rather than coming from the typical neutron star—the core of a star that has exploded and can no longer undergo nuclear fusion—the pulses are emitted by a pair of stars locked in a cosmic dance with one another.

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.

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,
