Mysterious Repeating Radio Signal Reveals New Star Duo
Imagine a radio signal from far, far away, like a cosmic heartbeat, repeating every two hours.
Scientists have found this signal coming from a pair of stars that circle each other very closely, called ILT J1101.
One star is a white dwarf, and the other is a red dwarf.
These stars' magnetic fields interact and create radio waves.
This discovery is a big deal because it shows that white dwarfs, which scientists didn't think could make such signals, actually can!
Scientists hope studying this system will help them understand other mysterious signals and learn more about the universe.
Astronomers detected a repeating radio signal from deep space, repeating every 125.5 minutes.
The signal originates from a binary star system in the Ursa Major constellation.
The binary system, named ILT J1101, consists of a white dwarf and a red dwarf.
The discovery challenges existing views of which celestial objects can generate radio signals.
Scientists plan further studies to understand the white dwarf's properties and the signal's origins.
