Radio Signals From A Galaxy Light Years Away Have Been Reported

Ever since FRBs were first detected, scientists have been piecing together the signals' observed characteristics to come up with models that might explain the sources of the mysterious bursts and provide some idea of the environments in which they occur.

The most recent spate of FRBs, including the 'repeater, ' was discovered by the Canadian Hydrogen Intensity Mapping Experiment (or CHIME), which picked up a total of fourteen FRBs, including six from the same source.

Scientists around the world are abuzz at the news that a radio telescope in Canada has detected a slew of high-energy astronomical phenomena known as fast radio bursts (FRBs). 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 findings are just the beginning of CHIME's discoveries", added Stairs.

The researchers said that studying the fast radio bursts is a hard task because they're rare and only occur once.

Because it bursts again and again - with periods of what seem like quiescence in between - astronomers have been able to catch it in the act, and trace it to its source, a galaxy about 3 billion light-years away. Ingrid stairs who is the member of CHIME Team have had an interview in which he said that till now there had been one repeated FRB and there are clearer confirmations that there would be more suggestions like there have been before out there. Prior to this, only 50 FRBs had ever been observed by humans, only one of which was a repeater. "But it has to be in some special place tog I've us all the scattering that we see".

Scientists have been able to find about 60 single FRBs and two that repeat, the BBC reported.

Scientists believe there could be up to a thousand FRBs in the sky every day.

It is not known where they originate from though it is thought they come from sources billions of light years away in the Milky Way. The signals are nothing but fast radio burst, only the second repeating burst to be recorded.

The first one, deemed FRB 121102, was discovered in 2015 by the Arecibo radio telescope, and it was revealed in 2018 that the bursts release an enormous amount of energy. The detection of these repeated signals could nevertheless help us to see a little more clearly.

The new FRBs are are also at unusually low radio frequencies. Harvard University Professor Abraham Loeb past year said FRBs could originate from planet-sized transmitters that are used to propel giant spaceships by bouncing radio waves off their huge reflective sheets. What's more the lowest radio frequency recorded previously was 700 Mhz.
