“Repeating radio signals coming from a mystery source far beyond the Milky Way have been discovered by scientists. While one-off fast radio bursts (FRBs) have been detected in the past, this is the first time multiple signals have been detected coming from the same place in space.”(1)
“FRBs are radio signals from deep space that last for just a few milliseconds. Since their discovery over a decade ago, scientists have been searching for more to try to understand their origin. At present, there are several theories as to what they could be, with most involving some cataclysmic event like a supernova or a neutron star collapsing into a black hole.”(1)
The FRB 010724 coming from a source near the constellation Aquarius were seen to be circularly polarised, writes IFLScience.
Along with the FRBs, Petroff also detected a different kind of signal called peryton. This has been puzzling astronomers since being first detected in 1998.
Perytons last about half a second and the various frequencies arrive separately, usually the result of interference when passing through interstellar dust.
But perytons have been suspected to be of terrestrial origin as they are detected by many radio telescopes at a time, indicating a spread in the sky rather than coming from a distant source.
By ruling out various sources, and noting the time of appearance, Petroff realised the signals were occurring at daytime and during business hours.
A radio frequency interference monitor picked up signals coinciding with some perytons, further pointing to a local source.
Finally, the signals were traced to the microwave ovens in the observatory tea room. This was further corroborated by tests.”(2)
In this case they came from the same facility.
