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 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.
