Canada's new radio telescope has picked up a mysterious signal from deep in space with a frequency so low, it's never been detected before.
The odd signal has been classified as a Fast Radio Burst (FRB) - one of the most perplexing phenomena in the universe, of which only two dozen have ever been recorded, notes the Daily Mail. This allowed the scientists to assume that the signal source with the code name "FRB 180725A" was extremely powerful.
"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", he said a year ago. No FRB has ever been detected below 700 Mhz before.
A new telescope called the Canadian Hydrogen Intensity Mapping Experiment (CHIME) picked up the emission, which also has the lowest frequency of any burst recorded by our species.
The latest mystery signal was detected by CHIME, a state-of-the-art radio telescope that looks like a skateboarder's half-pipe in the mountains of British Columbia.
But FRB 180725A had a few more surprises in store.
The signal, which astronomers call Fast discrete pulse (FRB), had a frequency below 700 MHz for the first time in the history of observation.
Most of the time such kind of radio telescopes don't hear anything that's abnormal, but now an unexplained signal made its way through the noise.
As the Inquisitr previously reported, FRBs were first discovered in 2001 and documented only a decade ago.
"These events have occurred during both the day and night and their arrival times are not correlated with known on-site activities or other known sources of terrestrial RFI (radio frequency interference)". No one knows where they originate from or what they are exactly.
But despite FRBs' relative rarity in astronomy, they are probably a regular cosmic occurrence, Christopher Conselice, a professor of astrophysics at the University of Nottingham who was not involved in the discovery, told The Daily Mail.
'It could even be some other physical mechanism that we don't yet understand'.
According to Avi Loeb, a scientist at the Harvard-Smithsonian Center for Astrophysics, researchers have not been able to detect a source for any of the FRBs as of yet.
