A fantastically bright repeating radio signal from billions of light-years away has been discovered, only the second of its kind ever found. Scientists now believe these signals are much more common than previously thought.
The telescope was launched a year ago, detecting 13 of the radio bursts nearly immediately, including the repeater that was detected today.
The signal was detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a radio telescope designed and built by Canadian scientists.
While most previous FRBs had been recorded at frequencies around 1400MHz, these new bursts were collected at between 800MHz and 400MHz-the lowest frequency CHIME can detect. Among the FRBs, was the second ever repeating fast radio burst recorded.
Although there are still many questions about what exactly they are and what causes them, scientists believe they could be emanating from a powerful astrophysical phenomena billions of light years away. Once CHIME is running at full capacity, it may discover many, many more FRBs-potentially thousands per day. The first signal to do this was named FRB 112102 and was observed by accident in 2007.
Experts have debated whether black holes or super-dense neutron stars are responsible, but others have suggested more outlandish theories.

Didn't know about allegations Manafort shared polling
Manafort, who sat in a wheelchair during a court hearing in October, also has severe gout, his lawyers said. Ellis III in Northern Virginia for his conviction on eight felony counts of bank and tax fraud.
"And with more repeaters available for study, we may be able to understand these cosmic puzzles a bit better", Stairs added.
Scientists said that they have observed blasts of radio signals coming from deep in space.
Tom Landecker, CHIME team member from the National Research Council of Canada. Ingrid stairs who is the member of CHIME Team have had an interview in which he said that till now there had been one repeated FRB and there are clearer confirmations that there would be more suggestions like there have been before out there.
"When these bursts happen once only, it's really hard to figure out what created them", Cherry Ng, with the University of Toronto, told The Verge. The presence of FRBs and their promised regularity of activity brings hope of future discovery."If we had 1,000 examples, we would be able to say many more things about what FRBs are like", said Good. Today's shoe drop concerns "fast radio bursts" coming from a distant galaxy - but don't expect a secret message from an advanced civilization. But where can they come from?
Unbelievable - we're very much looking forward to that as well. "We would also like to study the properties of whole populations of FRBs and try to see if there are different sources that give rise to repeaters and non-repeaters".
In 2017, Professor Avi Loeb from the Harvard-Smithsonian Centre for Astrophysics his colleague Manasvi Lingam proposed that FRBs could be leakage from planet-sized alien transmitters, reported The Guardian.
