Fast Radio Bursts (FRB) is the name given to short intense pulses of radio waves.
These FRBs last longer than a microsecond and travel from many millions of miles away.
What causes these to occur remains a mystery.
Some hypothesise they stem from cosmic explosions – others are of the belief they come from sort of alien source, maybe even other beings.
Over the past ten years, over 60 FRBs have been discovered.
But despite this, only a few have been repeated.
And it’s these recurring FBRs which scientists are to study the origins of.
Now there appears to be breakthrough in the study.
Indeed, an international group of scientists claim they’ve now found the origin of the repeating FRBs, specifically the ones which was discovered last year.
The experts used eight of Earth’s most powerful telescopes – and it was from this that they were able to ascertain the source of the signal.
They believe it stems from a spiral galaxy, one similar to our Milky Way, only this one can be found some 500million light-years away from Earth.
This is now the fifth RB to be pinpointed back to that source in the galaxy.
And that makes it the closest ever to be discovered by scientists.
McGill University scientist Mohit Bhardwaj said: ”The FRB is among the closest yet seen, and we even speculated that it could be a more conventional object in the outskirts of our own galaxy.
“However, the observation proved that it’s in a relatively nearby galaxy, making it still a puzzling FRB but close enough to now study using many other telescopes.”

Scientists found this particular FRB using a gigantic telescope in Canada.
It was dubbed as the CHIME experiment.
The region in which the FRBs came from is estimated to be around seven light-years.
This would mean, according to the scientists, that they stem from cosmic processes – but this is yet to be confirmed.
The first burst – named FRB 121102 – is considered the first to come with a small dwarf galaxy.
Benito Marcote, lead study author from the Joint Institute for VLBI in Europe, said: “The multiple flashes that we witnessed in the first repeating FRB arose from very particular and extreme conditions inside a very tiny [dwarf] galaxy.”
”This discovery represented the first piece of the puzzle but it also raised more questions than it solved, such as whether there was a fundamental difference between repeating and non-repeating FRBs.
“Now, we have localised a second repeating FRB, which challenges our previous ideas on what the source of these bursts could be.
FRBs remain a mystery though scientists are moving closer to finding source for them.
Some believe they show evidence that they’re being emitted from “powerful astrophysical objects”, such as a black hole or material from a star.
Others, however, believe they come from alien spaceships.
