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.

A decade-long radio mystery has finally been solved: astronomers have linked repeating pulses to a white dwarf and red dwarf in a tight orbit. Every two hours, their magnetic interactions generate radio bursts,

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,
