Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada.

The precise nature and origin of the blasts of radio waves is unknown.

Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away.

Such an event has only been reported once before, by a different telescope.

"Knowing that there is another suggests that there could be more out there," said Ingrid Stairs, an astrophysicist from the University of British Columbia (UBC).

"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."

The CHIME observatory, located in British Columbia's Okanagan Valley, consists of four 100-metre-long, semi-cylindrical antennas, which scan the entire northern sky each day.

The telescope only got up and running last year, detecting 13 of the radio bursts almost immediately, including the repeater.

The research has now been published in the journal Nature.

"We have discovered a second repeater and its properties are very similar to the first repeater," said Shriharsh Tendulkar of McGill University, Canada.

"This tells us more about the properties of repeaters as a population."

FRBs are short, bright flashes of radio waves.

Mystery cosmic radio bursts pinpointed

So far, scientists have detected about 60 single fast radio bursts and two that repeat. They believe there could be as many as a thousand FRBs in the sky every day.

There are a number of theories about what could be causing them.

They include a neutron star with a very strong magnetic field that is spinning very rapidly, two neutron stars merging together, and, among a minority of observers, some form of alien spaceship.

Fast radio bursts are not exceedingly rare, however, this is only the second repeating FRB to be measured in history.

The finding was recently published in the journal Nature and was conducted by a CHIME/FRB Collaboration, including contributors from Harvard University, MIT, University of British Columbia, Space Science Institute and The University of Toronto among others.

The radio bursts were detected by the brand new Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope. This is a notable discovery from the telescope which wasn't at full capacity in the summer of 2018 when the radio bursts were detected. The CHIME Observatory sits in the Okanagan Valley in British Columbia and consists of four 100-meter-long antennas that are constantly scanning the sky.

CHIME is an interferometric radio telescope and was commissioned to serve two main functions. One is to measure how dark energy behaves and the acceleration of the Universe. The second primary function is to detect and monitor pulsars and radio transients such as these fast radio bursts. CHIME is sensitive enough to potentially detect dozens of FRBs every day.

The repeating radio burst, named FRB 180814.J0422+73, was a set of six repeating radio signals originating 1.5 billion light-years away. To put that distance into perspective, the Andromeda galaxy is a mere 2.537 million light years.

According to Atlas Of The Universe, the following is contained within 1 billion light-years from Earth:

There remain questions surrounding the source of these repeating radio bursts. While some speculate the signal could be from extraterrestrial life, there is no evidence supporting they are from aliens.

The first detected radio bursts were measured at a frequency of 700 megahertz and the recent CHIME detection included frequencies as low as 400 megahertz. The first detected repeating radio bursts (FRB 121102) originated 3 billion light-years away from a dwarf galaxy. Scientists believe the source of FRB 121102 could be from a highly magnetized neutron star or highly magnetized pulsars traveling through an asteroid belt, among others.

What's exciting is that CHIME isn't even fully operational yet and it has already had this significant observation. The more we are able to detect these repeating radio bursts the better we are able to study where they originate and what causes them.</s>Astronomers in Canada have detected a mysterious volley of radio waves from far outside our galaxy, according to two studies published Wednesday in Nature.

What corner of the universe these powerful waves come from and the forces that produced them remain unknown.

The so-called repeating fast radio bursts were identified during the trial run last summer of a built-for-purpose telescope running at only a fraction of its capacity.

Known by its acronym CHIME, the world’s most powerful radio telescope, spread across an area as big as a football pitch, is poised to detect many more of the enigmatic pulses now that it is fully operational.

“At the end of the year, we may have found 1,000 bursts,” said Deborah Good, a PhD student at the University of British Columbia and one of 50 scientists from five institutions involved in the research.

Fast radio bursts (FRBs) flash only for a micro-instant, but can emit as much energy as the sun does in 10,000 years.

Exactly what causes these high-energy surges of long waves at the far end of the electromagnetic spectrum remains the subject of intense debate.

More than 60 bursts have been cataloged since 2007, but only one other, observed in 2012 at the Arecibo Observatory in Puerto Rico, was a repeater.

“FRBs, it seems, are likely generated in dense, turbulent regions of host galaxies,” Shriharsh Tendulkar, a corresponding author for both studies and an astronomer at McGill University, told AFP.

Cosmic convulsions created by the turbulent gas clouds that give rise to stars, or stellar explosions such a supernovae, are both possible incubators.

“The fact that the bursts are repeated rules out any cataclysmic models in which the source is destroyed while generating the burst,” Tendulkar added.

“An FRB emitted from a merger of two neutron stars, or a neutron star and a black hole, for example, cannot repeat.”

It is not yet clear whether the breeding grounds of repeating bursts are different from those that produce only a single radio pulse.

Significantly, the 2012 and 2018 “repeaters” have strikingly similar properties.

CHIME (Canadian Hydrogen Intensity Mapping Experiment) also spotted a dozen single burst radio waves, but with an unusual profile.

Most FRBs spotted so far have wavelengths of a few centimeters, but these had intervals of nearly a meter, opening up a whole new line of inquiry for astronomers.

Could these enigmatic radio pulses point to intelligence elsewhere in the Universe? Might they be messages in a bottle?

“As a scientist I can’t rule it out 100 percent. But intelligent life is not on the minds of any astronomer as a source of these FRBs.”

Constructed in British Columbia, CHIME is composed of four, 100-meter long half-pipe cylinders of metal mesh, which reconstruct images of the sky by processing the radio signals recorded by more than a thousand antennas.

“This signal processing system is the largest of any telescope on Earth,” the researchers said in a communique.

The other institutions with leading roles are the University of Toronto, the National Research Council of Canada, and the Perimeter Institute.</s>The discovery of the extragalactic signal is among the first, eagerly awaited results from the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a revolutionary radio telescope inaugurated in late 2017 by a collaboration of scientists from the University of British Columbia, McGill University, University of Toronto, Perimeter Institute for Theoretical Physics, and the National Research Council of Canada.

In a resounding endorsement of the novel telescope's capabilities, the repeating FRB was one of a total of 13 bursts detected over a period of just three weeks during the summer of 2018, while CHIME was in its pre-commissioning phase and running at only a fraction of its full capacity. Additional bursts from the repeating FRB were detected in following weeks by the telescope, which is located in British Columbia's Okanagan Valley.

Discovery of second repeating FRB suggests more exist

Of the more than 60 FRBs observed to date, repeating bursts from a single source had been found only once before—a discovery made by the Arecibo radio telescope in Puerto Rico in 2015.

"Until now, there was only one known repeating FRB. Knowing that there is another suggests that there could be more out there. 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," said Ingrid Stairs, a member of the CHIME team and an astrophysicist at UBC.

Before CHIME began to gather data, some scientists wondered if the range of radio frequencies the telescope had been designed to detect would be too low to pick up fast radio bursts. Most of the FRBs previously detected had been found at frequencies near 1400 MHz, well above the Canadian telescope's range of 400 MHz to 800 MHz.

The CHIME team's results—published January 9 in two papers in Nature and presented the same day at the American Astronomical Society meeting in Seattle—settled these doubts, with the majority of the 13 bursts being recorded well down to the lowest frequencies in CHIME's range. In some of the 13 cases, the signal at the lower end of the band was so bright that it seems likely other FRBs will be detected at frequencies even lower than CHIME's minimum of 400 MHz.

FRB sources likely to be in 'special places' within galaxies

The majority of the 13 FRBs detected showed signs of "scattering," a phenomenon that reveals information about the environment surrounding a source of radio waves. The amount of scattering observed by the CHIME team led them to conclude that the sources of FRBs are powerful astrophysical objects more likely to be in locations with special characteristics.

"That could mean in some sort of dense clump like a supernova remnant," says team member Cherry Ng, an astronomer at the University of Toronto. "Or near the central black hole in a galaxy. But it has to be in some special place to give us all the scattering that we see."

A new clue to the puzzle

Ever since FRBs were first detected, scientists have been piecing together the signals' observed characteristics to come up with models that might explain the sources of the mysterious bursts and provide some idea of the environments in which they occur. The detection by CHIME of FRBs at lower frequencies means some of these theories will need to be reconsidered.

"Whatever the source of these radio waves is, it's interesting to see how wide a range of frequencies it can produce. There are some models where intrinsically the source can't produce anything below a certain frequency," says team member Arun Naidu of McGill University.

"[We now know] the sources can produce low-frequency radio waves and those low-frequency waves can escape their environment, and are not too scattered to be detected by the time they reach the Earth. That tells us something about the environments and the sources. We haven't solved the problem, but it's several more pieces in the puzzle," says Tom Landecker, a CHIME team member from the National Research Council of Canada.

More information: Observations of fast radio bursts at frequencies down to 400 megahertz, Nature (2019). DOI: 10.1038/s41586-018-0867-7</s>Fast radio bursts (FRBs), mysterious high-energy astrophysical phenoma that have defied explanation, have been blamed on everything from aliens to microwave ovens. They are incredibly strong signals that have puzzling mathematical regularity, and scientists believe they are coming from deep space.

Now, a recently constructed telescope in Canada has detected 13 FRBs from deep space, including one that flashed repeatedly six times. The "repeater" is only the second known one of its kind to have been discovered.

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope in British Columbia made these observations from July to August 2018 during its "pre-commissioning" phase before it was even fully operational.

"CHIME reconstructs the image of the overhead sky by processing the radio signals recorded by thousands of antennas with a large signal-processing system," Kendrick Smith, of the Perimeter Institute for Theoretical Physics in Ontario, told Space.com. "CHIME's signal-processing system is the largest of any telescope on Earth, allowing it to search huge regions of the sky simultaneously."

The repeater, called FRB 180814.J0422+73, is about 1.5 billion light-years away from Earth. While that distance seems hard to fathom, it's actually two times closer than the first-discovered repeater, FRB 121102, which has sent out dozens of signals over the past several years.

Now with these new discoveries from CHIME, the number of FRBs recorded has increased by 20 percent. Astronomers also believe now that FRBs may be more common than previously thought but that technology hasn't caught up yet to detect all of them.

CHIME is groundbreaking also because its range is from 400 to 800 megahertz MHz, whereas previously discovered FRBs had radio frequencies around 1,400 MHz.

"[FRB] Sources can produce low-frequency radio waves, and those low-frequency waves can escape their environment and are not too scattered to be detected by the time they reach the Earth," CHIME team member Tom Landecker, from the National Research Council of Canada, told Space.com. "That tells us something about the environments and the sources...We haven’t solved the problem, but it’s several more pieces in the puzzle."

While CHIME may be leading the way in finding low-frequency FRBs, another radio telescope picked up on a unique FRB a few years ago that shed light on its mysterious origin and helped lay the groundwork for further analysis of matter in our universe.

While scientists still haven't exactly pinpointed whether or not FRBs all come from the same type of source or are vastly different in origin, scientists in Australia believe they discovered one source back in 2015.

Or at least, they confirmed the source of one of the fast radio bursts: a galaxy roughly 6 billion light-years away in the Canis Major constellation, reported Science News. That's a long way away, proving once and for all that these perplexing radio signals are not coming from within our own galaxy.

The bursts have been difficult to pinpoint, in part because they last only a few milliseconds but also because only several dozen of them have ever been detected. But a burst captured by the Parkes radio telescope in Australia in April of 2015, was followed by a faint radio glow that slowly faded over the course of six days. This additional glow offered enough information for scientists to trace the burst back to its origin, a distant elliptical galaxy.

Scientists suspected that the burst might have been generated from a merging pair of neutron stars, though this is just one hypothesis. It's also possible that fast radio bursts come in several different varieties and have different sources. That this particular burst's galaxy of origin has been pinpointed does not mean that the origin of the phenomenon itself has been solved. There's much still to learn about these peculiar signals.

Interestingly, the search for this burst's source might also have solved another riddle of the universe: the so-called "missing matter" problem. There should be much more matter in our universe than scientists have been able to detect so far, at least according to current models of the universe. This fast radio burst showed a lot of "wear and tear," however — and that's evidence that it must have bumped into lots of matter during its journey through the space between galaxies.

This could be the missing matter that scientists have been looking for, invisible ions hidden in the darkness of intergalactic space.

These are all exciting finds, proof that there's a lot of good science that can come from studying these mystifying signals, whether they lead to aliens, merging neutron stars or something else entirely.

Burst is one of 13 signals discovered by a new telescope in Canada.</s>Mysterious repeating energy bursts from deep space that some experts have suggested could be evidence of advanced aliens have been detected for only the second time in history.

Fast radio bursts (FRBs) are millisecond-long flashes of radio waves whose origin is unknown.

Most scientists believe they are generated by powerful astrophysical phenomena such as black holes or super-dense neutron stars. But a few have suggested more outlandish theories.

Prof Avi Loeb, from the Harvard-Smithsonian centre for astrophysics in Cambridge, Massachusetts, believes they could be evidence of incredibly advanced alien technology.

FRBs were first detected accidentally in 2007, when a burst was spotted in radio astronomy data that had been collected in 2001.

The new discovery reported in the journal Nature was made by a Canadian-led team of astronomers on the hunt for FRBs.

Over a period of three weeks last summer, the team detected 13 of the flashes using a new type of radio telescope, the Canadian Hydrogen Intensity Mapping Experiment (Chime).

One of the FRBs was repeating. Of more than 60 FRBs detected to date, such repeating bursts have only been picked up once before, by the Arecibo radio telescope in Puerto Rico in 2015.

Where the FRBs come from is not known, although they are thought to emanate from sources billions of light years away outside our galaxy, the Milky Way.

Chime astrophysicist Dr Ingrid Stairs, from the University of British Columbia in Vancouver, said: “Until now, there was only one known repeating FRB. Knowing that there is another suggests that there could be more out there.

“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.”

Most of the 13 FRBs showed signs of “scattering” that suggest their sources could be powerful astrophysical objects in locations with special characteristics, the scientists said.

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. Or near the central black hole in a galaxy. But it has to be in some special place to give us all the scattering that we see.”

The new FRBs are are also at unusually low radio frequencies. Most previously detected FRBs have had frequencies of around 1,400 megahertz (MHz), but the new ones fell within a range below 800 MHz.

In 2017 Loeb and Harvard colleague Manasvi Lingam proposed that FRBs could be leakage from planet-sized alien transmitters.

Rather than being designed for communication, they would more likely be used to propel giant space ships powered by light sails.

A light sail works by bouncing light, or in this case radio beams, off a huge reflective sheet to provide forward thrust.

Loeb, who discusses the idea in a paper published in the Astrophysical Journal Letters, said: “An artificial origin is worth contemplating and checking.”</s>The CHIME radio telescope in Canada has spotted repeated fast radio bursts coming from the same region in space.

For the second time, astronomers have detected fast radio bursts (FRBs) coming from the exact same region in space outside of the Milky Way, which makes this the first time that they have spotted more than one set of these ubiquitous radio waves in the same location.

As ScienceAlert report, even when these fast radio bursts are detected, they are normally never seen again. And as scientists are still not certain what these FRBs really are, this makes things all the more baffling.

Astrophysicist Ingrid Stairs, from the University of British Columbia in Canada, explained that with the new discovery of a second set of repeated FRBs, scientists will have much more information at their disposal about this mysterious phenomenon.

“Until now, there was only one known repeating FRB. Knowing that there is another suggests that there could be more out there. 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.”

The fast radio bursts that were recently detected are officially called FRB 180814.J0422+73, and back in August 2018 these FRBs were observed repeating themselves six times, after they were first spotted by the Canadian Hydrogen Intensity Mapping Experiment radio telescope (CHIME).

When looking at both new and repeated FRBs, the CHIME radio telescope has picked up an astonishing 13 new fast radio bursts and, even better, these observations were only test ones for this particular telescope. Which means that as it wasn’t operating at maximum capacity, in the future when it is, it is very possible that even more FRBs will be detected coming from the same area.

The first repeating fast radio bursts that astronomers originally picked up were found to emanate from FRB 122201, which is located three billion light-years away from Earth. However, this is pretty much all scientists know with much certainty about this signal right now.

FRB 180814.J0422+73, by contrast, is much closer to Earth, although these repeated signals were still found to be coming from another galaxy 1.5 billion light-years away from the Milky Way.

Physicist Arun Naidu, from McGill University in Canada, has noted, “Whatever the source of these radio waves is, it’s interesting to see how wide a range of frequencies it can produce. There are some models where intrinsically the source can’t produce anything below a certain frequency.”

Until CHIME or other radio telescopes pick up further FRBs, the two new studies which have just been published about the repeating fast radio bursts can be read here and here in Nature.</s>Far outside our Milky Way galaxy, something is causing repeating short bursts of radio waves to be released into space. Scientists have recorded the second repeating fast radio burst to be discovered, according to a study published Wednesday in the journal Nature.

The finding was also presented at the 233rd meeting of the American Astronomical Society in Seattle.

These radio bursts are only millisecond-long radio flashes, and such rapid bursts themselves aren’t rare in space.

But this is only the second one that has been found to repeat. The mystery about why these bursts happen and where they come from continues, which always spurs believers to think that advanced extraterrestrial civilizations are creating them.

The first one, deemed FRB 121102, was discovered in 2015 by the Arecibo radio telescope, and it was revealed in 2018 that the bursts release an enormous amount of energy.

This new repeating fast radio burst is called FRB 180814.J0422+73 and was recorded six times coming from the same location, 1.5 billion light-years away.

This is one of the very first detections made by the new Canadian Hydrogen Intensity Mapping Experiment, or CHIME. The radio telescope was still in its pre-commissioning phase and operating with only a small amount of its full capacity in the summer of 2018 when it detected this and 12 singular fast radio bursts.

And although this new detection doesn’t solve the biggest mysteries surrounding the radio bursts, the researchers who recorded it believe that other repeating fast radio bursts will be found — which could allow them to figure out where they originate.

“Knowing that there is another suggests that there could be more out there,” said Ingrid Stairs, a member of the CHIME team and an astrophysicist at the University of British Columbia. “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.”

One hypothesis is that powerful astrophysical phenomena are causing them. The first repeating fast radio burst was recorded at a frequency of 700 megahertz, but some of the bursts CHIME recorded were as low as 400 megahertz.

“[We now know] the sources can produce low-frequency radio waves and those low-frequency waves can escape their environment, and are not too scattered to be detected by the time they reach the Earth,” Tom Landecker, a CHIME team member from the National Research Council of Canada, said in a statement. “That tells us something about the environments and the sources. We haven’t solved the problem, but it’s several more pieces in the puzzle.”

The low frequency of this new detection could mean that the source of the bursts differ. “Scattering” was detected in the fast radio bursts, which is a phenomenon that helps determine more about the environment surrounding the origin.

The CHIME team believes this scattering is indicative of powerful astrophysical objects at the source of the bursts.

“That could mean [the source is] in some sort of dense clump like a supernova remnant,” team member Cherry Ng, an astronomer at the University of Toronto, said in a statement. “Or near the central black hole in a galaxy. But it has to be in some special place to give us all the scattering that we see.”

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.</s>Scientists have detected the second repeating fast radio burst (FRB) ever recorded, a discovery that may help determine the origin of these mysterious signals which have been linked with advanced alien technology in the past.

Some scientists also believe that FRBs emanate from powerful astrophysical phenomena billions of light years away. However, the source of these signals, originating from far outside our Milky Way galaxy, are not well understood.

In 2017, Harvard scientists have speculated that these FRBs might be leakage from planet-sized transmitters powering interstellar probes in distant galaxies. They said that since a natural origin can not be identified, an artificial or alien origin can be contemplated.

“Whatever the source of these radio waves is, it’s interesting to see how wide a range of frequencies it can produce. There are some models where intrinsically the source can’t produce anything below a certain frequency,” said Arun Naidu of McGill University in Canada, who was part of the team that detected the signal.

The discovery of the extragalactic signal is among the first, eagerly awaited results from the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a radio telescope inaugurated in 2017.

“Until now, there was only one known repeating FRB. Knowing that there is another suggests that there could be more out there,” said Ingrid Stairs, a member of the CHIME team.

“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,” said Stairs, an astrophysicist at University of British Columbia in Canada.

The repeating FRB was one of a total of 13 bursts detected over a period of just three weeks during the summer of 2018, while CHIME was in its pre-commissioning phase and running at only a fraction of its full capacity.

Additional bursts from the repeating FRB were detected in following weeks by the telescope, which is located in British Columbia’s Okanagan Valley.

Of the more than 60 FRBs observed to date, repeating bursts from a single source had been found only once before -- a discovery made by the Arecibo radio telescope in Puerto Rico in 2015.

The majority of the 13 FRBs detected showed signs of “scattering,” a phenomenon that reveals information about the environment surrounding a source of radio waves.

The amount of scattering observed by the CHIME team led them to conclude that the sources of FRBs are powerful astrophysical objects more likely to be in locations with special characteristics.

The detection by CHIME of FRBs at lower frequencies means some of these theories will need to be reconsidered.</s>Astronomers are more than a little excited with the second ever detection of a repeating fast radio burst in deep space.

Nothing intrigues an astronomer more than a deep space mystery, and now a team of 13 researchers from Canada has stumbled on one of the biggest mysteries around.

The University of British Columbia team using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope revealed the discovery of a repeating fast radio burst (FRB) – whereby incredible amounts of energy are emitted for just a few milliseconds.

Containing the power of approximately 500m suns, the burst is highly significant because it is only the second repeating one ever discovered, the first being discovered by the Arecibo radio telescope in Puerto Rico in 2012.

Publishing its findings to two different papers in Nature (here and here), the team said this latest repeating FRB was one of 13 new bursts detected in the space of just two weeks in the summer of 2018. While most FRBs have been spotted at wavelengths of a few centimetres, the latest FRBs were detected at wavelengths of nearly a metre.

Unlike typical FRBs that come and go, the discovery of a repeating FRB is vital to increasing our understanding of them, as we are able to train our radio telescopes towards them to study them further. In the meantime, the researchers believe they may be able to find 1,000 more FRBs by the end of the year.

“[We now know] the sources can produce low-frequency radio waves and those low-frequency waves can escape their environment, and are not too scattered to be detected by the time they reach the Earth,” said Tom Landecker of the CHIME team. “That tells us something about the environments and the sources. We haven’t solved the problem, but it’s several more pieces in the puzzle.”

Because of their intensity in energy and mysterious origins, claims that they could be alien in design continue to be suggested. While quite unlikely, an intense beam of light reaching Earth from deep space sounds similar to a recent suggestion from MIT researchers regarding contact with distant civilisations.

The proposal put forward by James Clark was that if a high-powered laser up to 2MW in power was focused through a 30- to 45-metre telescope, it would produce a beam powerful enough to stand out from the intensity of the sun.
Scientists announce through the Nature journal, the discovery of 13 deep-space fast radio bursts (FRBs), named FRB 180814, by the CHIME radio telescope in British Columbia, Canada.
