Scientists have caught a unusual signal from deep space

Scientists Pick Up First Mysterious Radio Signal From Deep Space Canada telescope picks new radio signal from distant planet, scientists puzzled over source

As the Inquisitr previously reported, FRBs were first discovered in 2001 and documented only a decade ago. Since 2007, there have been around 30 confirmed sightings.

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.

"The automated pipeline triggered the recording to disk of ~20 seconds of buffered raw intensity data around the time of the FRB". The signal was detected at frequencies as low as 580 MHz, making it the first known fast radio burst below 700 MHz.

"Additional FRBs have been found since FRB 180725A and some have flux at frequencies as low as 400 MHz". The burst quickly disappears after 2 milliseconds. Fast radio bursts are not uncommon, but are considered special because no one knows what their sources are.

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.

Foodora stops food delivery services in Australia
When Mr Klooger joined Foodora two years ago, he was paid $14 per hour plus $5 per delivery on an older contract. According to John Chessal, a deliver rider, Foodora's closing was "nice news".

The Canadian Hydrogen Intensity Mapping Experiment - or CHIME - detected the odd noise known as a fast radio burst on July 25, BGR.com reported. Usually, this radio telescope, as well as the other ones, doesn't detect anything interesting.

Mysterious radio signals emitted from across the universe. 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.

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.

In an interview with the Daily Mail, astrophysics professor Christopher Conselice of the University of Nottingham in the United Kingdom discusses the possible sources of FRBs, noting that the recently-discovered low-frequency signals might shed new light into what causes this intriguing phenomenon.

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. Studying the peculiar signal could give astronomers better clues as to how these extragalactic radio waves form and where they're coming from.
