Astronomers have discovered that a pair of stars—one white dwarf and one red dwarf—are sending out radio pulses every two hours. This is the first time scientists have confirmed the source of such signals,

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,
