Not having worked for a year, a new radio telescope in Canada, caught a very odd signal.
As a result, scientists believe that the source (whatever it is - PRESUMABLY ALIENS, THOUGH) is likely to be extremely powerful.
Theories suggest the signal, named FRB 180725A, could originate from a black hole - or even an alien civilisation.
If you haven't heard of fast radio bursts (FRBs), they're some of the most explosive and mysterious events in the Universe. Researchers claim that this is the lowest frequency FRB ever recorded emitted from across the universe.
For example, FRB 121102 was detected repeatedly over several years.
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.
But FRB 180725A had a few more surprises in store.
CHIME is located in British Columbia and its FRB from last month was reported in a post by the Astronomer's Telegram. In a diagram measuring the radio frequency over time, there is a clear bright streak beginning below 600 MHz.
"The event is clearly detected at frequencies as low as 580 MHz and represents the first detection of an FRB at radio frequencies below 700 MHz", Patrick Boyle wrote in the report. It was incredible how much energy is required to ensure that the radio signal could be done this way. The first radio burst was detected in 2001. Most of the time, radio telescopes like this don't hear anything out of the ordinary, but every so often an unexplained signal finds its way through the noise, and that's exactly what happened on July 25th.
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.
'They could be caused by exploding stars, supernova, exotic stars like pulsars, magnetars, neutron stars or massive black holes at the centre of distant galaxies. Scientists also believe that whatever produced the signal tends to be an extremely powerful extra-terrestial being.
FRBs detected by astronomers on Earth come from highly long distances and they're located so far off in space that we're not even able to see what's creating them.
