Detecting the repeatedly exploded force in the distant universe...Alien signal?

Astronomers are paying attention to the repeated detection of strong radio waves in space. Although the radio waves, which are believed to have occurred somewhere far away in space, have appeared repeatedly only once so far, this time around, it has been detected six times, drawing attention. 

Canadian astronomy research team announced that 13 rapid radio explosions were observed in August last year. Six of them have come from the same place repeatedly, according to the latest issue of the journal Nature. 

The research team said the new discovery was confirmed to have started about 1.5 billion light years away and named it "FRB 180814.J0422+73." It also explained that unlike most FRBs that are observed at 1400 MHz, the repetitive FRBs found were detected in the 400 MHz band, which is the lower bound for observation. 

The FRB is a radio wave produced by the Sun, releasing energy that it emits over 10,000 years in one-thousandth of a second, and is observed only for 10 millionth of a second. 

The origin of the FRB remains a mystery. Because of this, no exact substance has been identified. Academic circles say that it is caused by the collision of neutrons and supernova with strong magnetic fields in that it sends out strong radio waves for a short time. In addition, some people interpret the signals as signals from extraterrestrial intelligence. 

There have been only about 60 cases so far where the FRB has been observed in space. Among them, there were only one instance in November 2012. 
Back then, the 'repetitive FRB' was detected through the Aresibo radio telescope in Puerto Rico. According to the research, the repeated FRB started from galaxies about 3 billion light years away. 

The repeatedly detected FRB has been confirmed through CHIME, a strong radio telescope the size of a soccer field. The research team believes that the signal processing system of the Chime Telescope, 토토사이트 which processes radio signals collected with more than 1,000 antennas, played a major role in discovering the FRB. 

According to the research team, the recursive FRB was found in the process of partial test operation of the chime telescope. The research team expects to observe 1,000 FRBs by the end of this year as they are currently fully operational. 

"There has been only one observation of the repeated FRB so far," said Dr. Ingrid Stearns of the University of British Columbia who participated in the study. "We will be able to solve the mystery of the universe where and how the FRB is formed." 

Meanwhile, about 50 astronomers from five organizations, including the UBC, the University of Toronto, and the Perimeter Theoretical Physics Institute, participated in the study. The research team published the results in two papers in Nature and also presented them at the 233rd American Astronomical Society meeting in Seattle, Washington.
