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.

In the past three years, astronomers have discovered a mysterious new type of radio source. We call these long-period transients.

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.

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,
