Astronomers revealed Wednesday that they received mysterious signals from a distant galaxy.
In October researchers used a radio telescope in Australia to almost double the number of known fast radio bursts.
A number of speculations have been made about what could be causing the radio bursts - with theories ranging from stars exploding to alien life, however, currently, there is little evidence to prove either.
"Until now, there was only one known repeating FRB", said Dr. Ingrid Stairs, a member of the CHIME team and an astrophysicist at the University of British Columbia. That suggests there might be even more of them, too low to be picked up by CHIME, reported The Independent.
What is it?: Scientists remain undecided about what created the blasts. A minority of observers considered the possibility of an alien spaceship, BBC News reports.
Astronomers have detected dozens over the past decade - and have just announced they've found more of them, including a rare repeating signal.
Emily Petroff, an astronomer from ASTRON, the Netherlands Institute for Radio Astronomy, and an expert on FRBs, thought the methods "were particularly good" in these papers, and she liked how the CHIME astronomers didn't "over-interpret the data from shaky calibration".
Aaron Ramsey agrees to join Juventus from Arsenal in the summer
Ramsey will be the club's second highest paid player after Portuguese striker Cristiano Ronaldo (€ 31 million per year). Meanwhile, head coach Unai Emery had reservations about Ramsey's role in his squad.
Laerskool Schweizer-Reneke incident sparks memories of two similar school racism sagas
It is baffling to see that in 2019, we still have institutions that subject our children to this kind of psychological damage. Parents had dropped their children off on Wednesday morning for their first day of school at Schweizer-Reneke primary school.
Turkey says will launch Syria offensive if U.S. delays pullout
There are fears that the United States withdrawal will leave a door open for Turkey to assault the US-allied SDF fighters. Over the weekend, Kazakhstan took back five of its nationals who had fought for ISIS, as well as 40 women and children.
"Different emission mechanisms expect that FRBs will be emitted within a certain range of radio frequencies, much like a light bulb can not emit X-rays or a microwave oven can not emit ultraviolet light", Tendulkar told Gizmodo.
One reason CHIME was set on this search was that since the world first started detecting the phenomena, astroboffins have upped their estimates of how many such events exist to somewhere between hundreds and thousands a day.
They only last a few milliseconds before disappearing and come from distance places in the known universe.
The CHIME telescope found, as phrased by Nature.com, "the second known FRB that repeats, meaning that the radio flashes re-appear at the same point in the sky".
"By detecting and characterizing fast radio bursts at different frequencies, we can understand better which theories work and which do not", post-doctoral fellow at McGill University, Shriharsh Tendulkar, told Cnet. The source is from something with an extremely powerful magnetic field that produces a signal along the radio frequency band. That's about twice as close as the other repeater, FRB 121102.
The mystery of fast radio bursts has always been a large part of their appeal, Ng said.
That high rate of discovery suggests that FBRs, let alone repeating FBRs, may not be as unique as we think, said Perimeter Institute faculty member Kendrick Smith.
Since then, CHIME has been at its maximum capacity, and it is expected to detect many more of the enigmatic pulses now that it is fully operational.
