The source of mysterious signals coming from space has been revealed!

Australian scientists have identified the source of the repeating radio signals they discovered three years ago. Contrary to expectations, the mystery behind these signals may not be aliens, but a pair of interstellar dancing systems.

In 2021, Australian undergraduate student Tyrone O’Doherty detected an unusual radio wave that repeated every 18 minutes. The discovery challenged accepted pulsar theories because no pulsar sends a signal this slowly.
At the time, speculation about the source of the signal was rife. However, O’Doherty’s advisor Natasha Hurley said a natural explanation was more likely. Still, the mystery remained.
Hurley and his team discovered a new radio wave signal. Repeating every 2.9 hours, it is the slowest radio pulse yet detected from a red dwarf star. But there was something else unusual: The signals were connected to another object in binary orbit with the star.
“The source of the signal is most likely a white dwarf. This is the final stage of the life cycle of Sun-like stars,” Hurley explained. Researchers think that the stellar winds of these stars colliding with each other affect the magnetic fields and produce radio signals. FUTURE PLANS

Scientists aim to develop a comprehensive model that can explain such radio signals if more examples are found. “There may be different types of systems that can produce long-duration radio pulses,” Hurley said, adding that research will continue.
