On January 7, 2019, at the American Astronomical Society in Seattle, Deborah Good, an astronomer at the University of British Columbia, Canada, announced that they had monitored 13 fast bursts (FRBs) with the help of the Canadian CHIME telescope and included a very rare event. Repeated rapid radio storms come from about 1.5 billion light-years away, that is, from outside the Milky Way.

This is the second time that repeated rapid radio storms have been monitored. The last one occurred in 2012, about 2.5 billion light years away. It is called FRB 121102. And the frequency of the fast radio storms monitored was below 400 MHz, breaking the previous record of 700 MHz. <

According to Wikipedia, fast radio burst (FRB) is a high-energy astrophysical phenomenon that presents a transient radio pulse, sustaining only a few milliseconds of burst. These millisecond flashes are outside the Milky Way and have a very bright, unanalysed, wide bandwidth (in short, limited time domain, unlimited frequency domain). The frequency components of each burst depend on the amount of the burst and the delay time of different wavelengths.
