Repeated fast radio bursts from space make 'Alien Life' theories alive

Astronomers, including some of Indian origin, have detected repeating energy bursts from a single source from deep space for the second time in history -- giving impetus to theories that there could be evidence of advanced alien life. 

A Canadian - led team of scientists found the second repeating fast radio burst from the Canadian hydrogen Intensity mapping experiment telescope located in the mountains of British Columbia's Okanagan Valley.
Of the more than 60 fast radio bursts observed to date, repeating bursts from a single source had been found only once before --a discovery made by the Arecibo radio telescope in Puerto Rico in 2015 , the team said in a paper published in the Journal nature and presented at the American Astronomical Society meeting in Seattle on Wednesday.
Fast radio bursts are short bursts of radio waves coming from far outside of our Milky Way galaxy and scientist believe fast radio bursts emanate from powerful astrophysical phenomenon billions of light years away.

Whatever the source of this radio waves is,it's interesting to see how wide a range of frequencies it can produce.There some models where intrinsically the source can't produce anything below a certain frequency," said Arun Naidu of McGill University.

The repeating fast radio bursts was one of a total of 13 bursts detected over a period of just three weeks during summer of 2018. it came six times from same location ,1.5 billion light years away.
Additional bursts from the repeating fast radio burst were detected in following weeks."Until now , there was only one known repeating Fast radio burst.
