Second Mysterious Fast Radio Burst Detected From Outer Space

FRB Origin

Radio Signals From A Galaxy Light Years Away Have Been Reported

The only known repeating fast radio burst source -FRB 121102-has been localised to a star-forming region in a dwarf galaxy...

The flashes are very fast, only lasting no more than a millisecond and are flung out with a similar energy it takes our sun 12 months to produce. If scientists can figure out how FRBs ought to look when they leave their sources, they may be able to probe the intergalactic medium by studying the way the signals change.

These include exploding stars, stars with strong magnetic fields, stars merging together and yes, even the activites of alien lifeforms. What's more interesting is that one of the FRBs recorded by CHIME was repeating in nature and is claimed to have repeated six times from the same location. 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.

The other institutions with leading roles are the University of Toronto, the National Research Council of Canada, and the Perimeter Institute.

An event like this has only been reported once before after it was picked up by different telescope.

The FRBs discovered were omitting unusually low frequencies, with previously detected FRBs having frequencies around 1,400 megahertz and the new discoveries bellow 800 MHz. With a single exception that launches repeated fast radio bursts, the sources are never heard from again. The telescope is located at the Dominion Radio Astrophysical Observatory near Penticton, B.C. Dozens of mysterious radio signals have been noted by scientists with telescopes being used all over the world to track its source. It's easier, therefore, to measure and understand these effects at lower frequencies. "But intelligent life is not on the minds of any astronomer as a source of these FRBs".

Mysterious radio bursts detected deep in space could be evidence of aliens, researchers suggest. With this new discovery, astronomers are now hopeful of finding even more repeaters.

The last time they were detected was in 2007, when one was spotted by chance in radio astronomy data that had been collected in 2001.

Petroff said she wasn't surprised the CHIME astronomers found another repeating FRB, but she was surprised they found it so soon. "I look forward to the day when we have hundreds of repeaters".

NASA research scientist Dr Jessie Christiansen said "astronomers are super excited to find out more, but generally do not think it is extraterrestrial". While it was waiting to come fully online, it picked up these 13 FRBs.

He added: "That tells us something about the environments and the sources". He says that his areas of interests, apart from FRBs, are neutron stars and Nanohertz Gravitational Waves among others. Excitingly, it bears striking similarities to the first repeating FRB. An FRB is a very short pulse, akin to the kind of short pulses that come from pulsars, but unlike pulsars they mostly don't repeat. "But it has to be in some special place to give us all the scattering that we see".
