Second Ever Mysterious Signal Detected From The Deep Galaxy on Repeated Basisby jagadeesh kumar Analyst
In a second ever instance a mysterious signal is detected from far outside the galaxy by the Canadian Telescope. This telescope found the fast radio burst and detected around 13 radio bursts within three weeks of time span. As the Canadian hydrogen intensity mapping experiment (CHIME) which detected these signals was in its pre-commissioning stage, it was running only at the fraction of its fully capacity when it detected these bursts.
FAST RADIO BURSTS
Fast radio bursts, bright pulses of radio emissions seem to be originating from distant galaxies around 1.5 billion light years away and are only of milliseconds duration. Though there is no clarity around the source from where they originate but many believe that it’s from the extraterrestrials.
This CHIME observatory is located in the British Columbia’s Okanagan Valley and is equipped with four 100 m long, semi cylindrical antennas. These antennas are able enough to scan the entire northern skies on a daily basis.
The research has been published in the journal called Nature. Shirish Tendulkar of the Mc Gill University of Canada said that they had discovered a second repeater and the properties of it had resemblance to that of the first repeater.
Lingrid Stairs an astrophysicist from University of British Columbia (UBC) said that it was coming to know about another sound only reaffirms the possibility that there could be more. This would further help us understand the cosmic puzzles, information around their causes as well as origin.
Though scientists have been able to detect only 60 FRBS they do believe that there could be as many as over a thousand FRBS in the sky every day. As far as the theories around their causes, they are many probabilities including the merge of two neutron stars or a single neutron star that is rotating at a high speed.
