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 detected rare radio waves from a binary star system, challenging previous ideas about their origins. These pulses, lasting from milliseconds to minutes, arrive every 125.5 minutes. Scientists now believe they come from a white dwarf and red dwarf orbiting each other.

Astronomers have identified the possible origin of unusual cosmic radio bursts, revealing a previously unknown source in deep space.
