Scientists Pick Up Mysterious Radio Signal From Unknown Source In Deep Space

Alien fans, keep your eyes to the skies - Scientists in Canada have picked up a brief burst of radio which was sent by an unknown source in deep space.

The low frequency fast radio burst (FRB) lasted a matter of milliseconds, but researchers claim that the signal is the first radio emission received from across the universe with a frequency below 700 MHz - the lowest frequency FRB ever recorded, according to the MailOnline.

As a result, scientists believe that the source (whatever it is - PRESUMABLY ALIENS, THOUGH) is likely to be extremely powerful.

And the signal has even been named - well, branded - 'FRB 180725A'. Not very memorable that's for sure. Couldn't they have called it Hercules or Mysterio, or even Jeff or Ian or something?

Fast radio bursts are extremely uncommon and were first discovered in 2007 with only a handful observed ever since.

According to the MailOnline, the emission was detected by the Canadian Hydrogen Intensity Mapping Experiment telescope, which has been operating for less than a year.

Looks like it's doing a good job, then.

The FRB was detected by CHIME's expansive, four 100-meter-long (328ft) U-shaped cylinders on 25 July.

Patrick Boyle, of McGill University, first reported the detection of the FRB with a post on the astronomical publication Astronomer's Telegram.

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).

"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."

Mr Boyle adds: "Additional FRBs have been found since FRB 180725A and some have flux at frequencies as low as 400 MHz.

"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)."

Avi Loeb, of the Harvard-Smithsonian Center for Astrophysics research institute, said: "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.

"An artificial origin is worth contemplating and checking."

Helpfully, Dr Mark Halpern, of the University of British Columbia explained: "With the CHIME telescope we will measure the expansion history of the universe and we expect to further our understanding of the mysterious dark energy that drives the expansion ever faster.

"This is a fundamental part of physics that we don't understand and it's a deep mystery. This is about better understanding how the universe began and what lies ahead."

Nothing complex, then? Good. Carry on, LADs.
