UBC astronomers find unknown radio signals from distant galaxy

Radio Signals From A Galaxy Light Years Away Have Been Reported

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

Although the total number of FRBs scientists have detected is over 60 so far, this is only the second time an FRB has been repeated - the first time being in Puerto Rico in 2015, when the Arecibo radio telescope picked up the burst.

The telescope at the Canadian observatory that found the latest signals had previously detected the lowest frequency FRB known on record at wavelengths of 400 megahertz, according to Nature.

First spotted in 2007, scientists still don't know much about FRBs other than the fact they manifest as a transient radio pulse that last for a few milliseconds.

The University went on to say that FRBs are hard to research but could be linked to powerful astrophysical objects such as supernova remnants. "This is done using clever algorithms and a couple of giant computer clusters that sit beside the telescope and crunch away at the data in real time", Masui said in a statement.

The unusual beams are known as fast radio bursts (FRBs) - and last only a millisecond. Prior to this, only 50 FRBs had ever been observed by humans, only one of which was a repeater.

Having two sets of repeating bursts could also allow scientists to understand what distinguishes them from single bursts, helping them understand more about their source and watch for future blasts.

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. "But it has to be in some special place to give us all the scattering that we see", said Ng. We can be 100 percent sure that more such bursts will be found as this early into the lifespan of CHIME 13 of them were discovered.

The repeater, known as FRB 180814.J0422+73, is located about 1.5 billion light-years from Earth, astronomers told Space.com.

Three dead in double-decker bus crash in Ottawa
In September 2013, a horrific crash between a double-decker OC Transpo bus and a Via Rail train in South Ottawa killed six people. Ottawa Police Chief Charles Bordeleau said several people were trapped in the bus before being freed.


Probably most exciting of the new bursts is one that scientists saw repeat six times, apparently from the same location.

At distances of billions of light years it's obviously very hard to test any of these theories, but detecting more FRBs, especially those that have a habit of repeating, could bring us closer to an explanation. "We have not solved the problem, but it's several more pieces in the puzzle".

Professor Avi Loeb, from the Harvard-Smithsonian Centre for Astrophysics in the U.S., has previously said that FRBs could potentally be evidence of advanced alien technology. It appears at a wavelength of 400 megahertz, far lower than the previous record of 700 megahertz.

The low frequency of this new detection could mean that the source of the bursts differ.

États-Unis: Épidémie de gastro à bord d'une croisière, 475 passagers touchés
Mercredi dernier, après quatre jours de croisière, plus de 170 passagers et un membre de l'équipage commencent à tomber malades. En cause, pas un problème technique, mais une épidémie de gastro-entérite qui touche 475 passagers, rapporte Le Parisien .
