According to the Astronomer's Telegram, that signal is called a Fast Radio Burst, or FRB.
The pulse's fast, low frequency suggests that the blast was extremely bright and originated from an insanely powerful source somewhere in the cosmos.
This means that whatever produced the signal, which has been named "FRB 180725A", is likely to be extremely powerful. FRB signals were first observed in the year 2001 with help of pulsar survey of the Magellanic Clouds but scientists and researchers didn't mention them until 2007 in their studies and discoveries. Researchers claim that this is the lowest frequency FRB ever recorded emitted from across the universe.
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.
According to a report in The Astronomer's Telegram, on the morning of 25 July 2018, an array of radio telescopes in British Columbia, Canada, detected a very unusual FRB.
The post reads: "During its ongoing commissioning, CHIME/FRM detected FRB 180725A on 2018 July 25 at 17:59:43.115 UTC (18:59:43.15 BST/13:59:43.15 ET)". Because it had a frequency as low as 580 Mhz. It was incredible how much energy is required to ensure that the radio signal could be done this way. "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".
The signal, which astronomers call Fast discrete pulse (FRB), had a frequency below 700 MHz for the first time in the history of observation. CHIME was created to detect ancient radio waves sent out when the universe was just a toddler, some 6 billion to 11 billion years ago.
Whatever it is - black holes colliding, a star exploding, or just some aliens having a really loud party - we'll probably have to wait a long, long time before science can say for certain.
'It could even be some other physical mechanism that we don't yet understand'.
Mysterious radio signals emitted from across the universe.
Due to the unknown origins of FRBs, it has attracted the curiosity and scrutiny of alien hunters.
