Strange signals that have been coming from a mysterious object in a galaxy that is over 500 million light-years away is one puzzle that researchers are yet to solve.
These mysterious signals always appear every 16 days, with the same pattern and message.
However, experts have not deciphered these signals to make sense of what it all means, even though its origin has been established.
In 2017, a Harvard-Smithsonian Center for Astrophysics theorist, Avi Loeb, disclosed in a press release that:
“Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven’t identified a possible natural source with any confidence.”
Until recently, astronomers were unable to detect a pattern in these signals, which are now referred to as Fast Radio Bursts (FRBs).
Reports suggest that researchers in the past have detected similar signals; however, these appear at random intervals without a specifically timed progression, as we have seen with the recent signals.
The pattern was first detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB).
The CHIME/FRB then tracked the signals until they realized that it has a repeating pattern and appears within 16 days interval. The signal was labeled as FRB 180916.J0158+65.
Researchers have revealed that these bursts can sometimes be observed for four days before they cease for 12 days and then repeat the same pattern in the same circle.
Between September of 2018 and October of last year, the first 28 cycles were observed.
These signals were detected using the CHIME radio telescope in British Columbia.
Authors of this study believe that the discovery of a 16-day periodicity will provide an important clue to the nature of this mysterious object.
The report reads, in part:
“We conclude that this is the first detected periodicity of any kind in an FRB source. The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object,”
Theories About These Mysterious Radio Signals
Scientists are of the opinion that the FRB is coming from a spiral galaxy known as SDSS J015800.28+654253.0.
This galaxy is estimated to be located half a billion light-years from Earth.
