Repeating Radio Bursts Detected From A Galaxy 1.5 Billion Light-Years Away
10 January 2019 | https://www.forbes.com/sites/trevor...xy-1-5-billion-light-years-away/#516f5beb4223
Scientists recently measured mysteriously repeating radio signals coming from a galaxy 1.5 billion light-years away. The repeating signal was part of 13 fast radio bursts (FRBs) detected by a new telescope in Canada.
Fast radio bursts are not exceedingly rare, however, this is only the second repeating FRB to be measured in history.
The finding was recently published in the journal Nature and was conducted by a CHIME/FRB Collaboration, with the primary hubs of work taking place at McGill University (the PI institution), University of Toronto, the University of British Columbia and the Canadian National Research Council where CHIME is located.
The radio bursts were detected by the brand new Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope. This is a notable discovery from the telescope which wasn't at full capacity in the summer of 2018 when the radio bursts were detected. The CHIME Observatory sits in the Okanagan Valley in British Columbia and consists of four 100-meter-long antennas that are constantly scanning the sky.
CHIME is an interferometric radio telescope and was commissioned to serve two main functions. One is to measure how dark energy behaves and the acceleration of the Universe. The second primary function is to detect and monitor pulsars and radio transients such as these fast radio bursts. CHIME is sensitive enough to potentially detect dozens of FRBs every day.
The repeating radio burst, named FRB 180814.J0422+73, was a set of six repeating radio signals originating 1.5 billion light-years away. To put that distance into perspective, the Andromeda galaxy is a mere 2.537 million light years.
According to Atlas Of The Universe, the following is contained within 1 billion light-years from Earth:
The first detected radio bursts were measured at a frequency of 700 megahertz and the recent CHIME detection included frequencies as low as 400 megahertz. The first detected repeating radio bursts (FRB 121102) originated 3 billion light-years away from a dwarf galaxy. Scientists believe the source of FRB 121102 could be from a highly magnetized neutron star or highly magnetized pulsars traveling through an asteroid belt, among others.
What's exciting is that CHIME isn't even fully operational yet and it has already had this significant observation. The more we are able to detect these repeating radio bursts the better we are able to study where they originate and what causes them.

Quite understandable.In indians ny sirf 2 week main hamain itna pakka diyaa woh gareeb tu hazaron saal sy unhain jheel rahy hain.one of reason extra terrestrials avoiding earth .sochty hn gy wahan sab hi aisy hn gy
