"Until now there was only one FRB repeated each time", says Ingrid Stairs, an astrophysicist at the University of British Columbia (Canada) and lead author of the study published in Nature. Although the source of the object is still unknown, Loeb was one of the scientists suggesting that it was probably an alien probe falling off from the galaxy after completing its mission.
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.
Within weeks of CHIME's FRB-detecting software being activated last summer ― in what Lang said was only a testing phase that didn't run on full capacity ― CHIME detected these 13 new bursts.

"Until now, there was only one known repeating FRB". 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.
There's no definitive cause of these fast radio bursts and it's unclear what caused multiple FRBs from the same location. Observations of fast radio bursts at frequencies down to 400 megahertz.
Theories include a neutron star that has a strong magnetic field spinning rapidly, the merging of two neutron stars and even alien spaceships.
Artist's impression of the active galactic nucleus shows the supermassive black hole at the center of the accretion disk sending a narrow high-energy jet of matter into space, perpendicular to the disc in this image by Science Communication Lab in Kiel Germany, released on July 12, 2018. Most FRBs found are at frequencies near 1400 megahertz (MHz).More news: Netflix to track and stop users from sharing their accounts with friends
"At the end of a year we may have found 1,000 more bursts".
Shriharsh Tendulkar, an astronomer from the McGill Space Institute and a co-author of the new study, said radio frequencies help scientists understand possible emission mechanisms, or processes, of FRBs, and also the effects that the radio waves encounter as they travel through space.
But they have remained entirely mysterious, with little evidence at all of where they might be coming from.
Canadian astronomers have reportedly discovered a repetitive radio signal some 2.5 billion light-years away from Earth - only the second example known to mankind.More news: Democrats block Middle East bill in the Senate over shutdown
Of the 13 signals that were picked up, at least seven were recorded at 400 MHz - the lowest frequency of any such radio burst discovered till date. "But it has to be in some special place to give us all the scattering that we see", said Ng.
The other institutions with leading roles are the University of Toronto, the National Research Council of Canada, and the Perimeter Institute.More news: Women Develops Rare Condition That Leaves Her Unable To Hear Men
