Fast radio bursts, extremely short radio pulses of unknown physical origin that seem to come from outer space, usually these happen just once.
However, researchers recently picked up the sound of 10 repeated signals changing the scientific theory on how such sounds are created, according to a study published in Nature.
“Not only did these bursts repeat, but their brightness and spectra also differed from those of other (fast radio bursts),” Laura Spitler, the first author of the study, told Futurity.
The findings suggest that the waves come from a rotating neutron star not just a cataclysmic event as previously thought. Researchers believe that the origin of the repeated sounds is a distant galaxy.
The results were discovered using the Arecibo radio telescope in Puerto Rico, the largest of its kind.
