"Seeing these bursts with CHIME will give us a good idea about what FRBs are like and where they come from, by showing us more about how their brightness changes at different frequencies and what's happening to the signal on its way to Earth", she added. Knowing that there is another suggests that there could be more out there.
It's only the second time scientists have detected such a consecutive radio burst, reports the BBC.
"Now we're showing, no, at least one other repeats". Astronomers have grappled with this mystery for years because, while they continue to observe bursts, they are still unsure of what causes them.
Astronomers from the University of British Columbia have picked up 13 radio burst signals emanating from an unknown source they claim is about 1.5 billion light years away. Excitingly, it bears striking similarities to the first repeating FRB. "And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles - where they're from and what causes them", astrophysicist Ingrid Stairs told the Independent.
And if CHIME was able to make these detections before it was even fully up and running, the researchers are hopeful that the new radio telescope will help them find answers about these mysterious signals. Some scientists had anxious that the range of frequencies it can pick up would be too low for it to receive the FRBs - but it found far more than expected, and scientists expect it to identify even more.
The signal was detected by CHIME radio telescope in Canada, which managed to confirm six of the repeating bursts coming from the same location.
This repeating FRB is one of thirteen (the rest are single bursts) announced today by scientists. The telescope, which resembles a set of skateboarding half-pipes, was built as part of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) to record radio signals from outer space. "We haven't solved the problem, but it's several more pieces in the puzzle". It was one of 13 new FRBs the team detected during three weeks in the summer of 2018.
Another interesting twist has to do with the radio frequencies of the newly detected bursts.
Tom Landecker, a CHIME team member from the National Research Council, said the findings provide rich information about the sources and environments that generate fast radio bursts.
Team member Dr Cherry Ng, from the University of Toronto, said: "That could mean in some sort of dense clump like a supernova [exploding star] remnant".
At distances of billions of light years it's obviously very hard to test any of these theories, but detecting more FRBs, especially those that have a habit of repeating, could bring us closer to an explanation.
