Proof of LIFE: Scientists record mysterious radio signals from deep space

The uniquely shaped CHIME telescope in British Columbia

The uniquely shaped CHIME telescope in British Columbia

Recorded 13 times, they're originating from 1.5 billion light years away from Earth. Now a Canadian research team has found a repeating signal, only the second of its kind to be discovered.

Also, as radio waves travel through space, they interact with the electrons and magnetic fields present in the interstellar and intergalactic plasma.

Since the first discovery a decade earlier, roughly 60 bursts have been observed by five different telescopes worldwide.

All in all researchers spotted 13 bursts in a three week period. A second source of repeating fast radio bursts.

CHIME is a revolutionary new telescope, designed and built by Canadian astronomers.

The novel radio telescope features no moving parts.

A globuler cluster of stars captured by the Hubble telescope.

Using a series of four semicircular dishes, the telescope stays pointed consistently in the same direction, waiting to pick up signals.

The telescope has been in use for only a year, detecting 13 of the radio bursts nearly immediately, including the repeater. A new radio burst called FRB 180814.J0422+73 is now the second location in the sky to produce repeating radio bursts.

These events emit as much energy in one millisecond as the Sun emits in 10,000 years, but the physical phenomenon that causes them is unknown.

During a test run, with the extremely powerful radio telescope "Canadian Hydrogen Intensity Mapping Experiment" (Chime) in the canadian province of British Columbia were measured in the summer, a dozen of fast Radio bursts (Fast Radio Burst FRB), described the astronomers involved on Wednesday in the scientific journal "Nature".

"Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence", said Loeb. But these were found in the band between 400 and 800 MHz.

"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 in Canada, told AFP news agency. One other detail that needs to be considered would be that those bursts were collected at the lowest frequencies yet (400MHz to 800MHz).

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.

Or, more accurately, it was the only one. "It could be colliding black holes but you don't expect black holes to collide and then an hour later collide again, and then after that to collide again, right? But it has to be in some special place to give us all the scattering that we see".

The CHIME/FRB project is a combined effort between scientists from the Perimeter Institute for Theoretical Physics, the National Research Council of Canada, the University of British Columbia, McGill University and the University of Toronto.
