If that's not odd enough, this particular fast radio burst is incredibly low, in the 580 megahertz frequency range - almost 200 MHz lower than any other fast radio burst we've picked up on before.
This means that whatever produced the signal, which has been named "FRB 180725A", is likely to be extremely powerful.
Fast radio bursts are extremely uncommon and were first discovered in 2007 with only a handful observed ever since. Until now, no FRB below 700 MHz has been recorded.
The £12-million ($15.6 million) installation, set up in British Columbia, only began operations last year and is equipped with four 100-meter-long (328 feet) U-shaped cylinders, capable of recording ancient radio signals sent out when the universe was no more than six billion years old.
The latest FRB, which was detected by researchers at the Canadian Hydrogen Intensity Mapping Experiment in British Columbia, was allegedly the first to be heard between the much deeper frequency range of 400 to 800 MHz, rendering it a much lower signal than numerous FRB episodes before it. Because it had a frequency as low as 580 Mhz.
The signal, which astronomers call Fast discrete pulse (FRB), had a frequency below 700 MHz for the first time in the history of observation. The first radio burst was detected in 2001.
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. Not much is known about these short, high-energy signals, except that they have been attributed to a number of different potential sources, one more exotic than the other.
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.
The study of FRBs is only in its incipient stages and astronomers are confident that more such radio signals will be detected as our technology progresses.
'It could even be some other physical mechanism that we don't yet understand'.
Unfortunately, we'll have to wait a long time before we know for sure if these sounds come from black holes colliding, exploding stars or aliens lurking in space.
