move on to Starry, before ‘Fast Radio Burst’ Means one should know about FRB. FRBs are bright bursts of radio waves. Their duration is in the millisecond-scale. This is the reason why it is difficult to trace their source and determine their position in space. First ‘Fast Radio Burst’ was discovered in the year 2007. Since then scientists are working towards finding its original source. The thing to note is that these explosions produce as much energy in a thousandth part of a second as the Sun does in a year.
Fast radio bursts are so fast and unpredictable that they are difficult to observe. Although a radio telescope is engaged in this work. This telescope is located at the Dominion Radio Astrophysical Observatory in Canada, which is called the Canadian Hydrogen Intensity Mapping Experiment or CHIME. This telescope has been working since the year 2018 and continuously observes the sky and detects ‘Fast Radio Burst’.
The ‘fast radio burst’ usually lasts a few milliseconds and either subsides or in rare cases repeats. Now the signal received is about three seconds long. It is being called the longest duration fast radio burst ever. It is about a thousand times longer than an average FRB and has a heartbeat-like pattern, which repeats every 0.2 seconds and lasts for a total of 3 seconds.
It is labeled as FRB 20191221A. The source of this FRB is said to be in a galaxy several billion light-years away from Earth. As per reports, astronomers using the CHIME telescope spotted this signal on December 21, 2019. After which it was studied at the Kavli Institute for Astrophysics and Space of the Massachusetts Institute of Technology. According to postdoctoral researcher Daniele Michili here, we were monitoring it. He said that this signal is the longest lasting fast radio burst ever recorded.
