In the vast universe, there are mysterious rapid radio bursts, some of which have strange rhythms. In 2018, astronomers detected FRB 180916.J0158-65, which originated in a spiral galaxy about 500 million light-years away. After 13 months of continuous observation, astronomers discovered a highly repetitive rhythmic pattern.

In a peer-reviewed paper (arXiv preprint server archive), a team of scientists working with the CHIME/FRB project in Canada described their observations and analysis between September 2018 and October 2019.
Using a large ground-based CHIME telescope in British Columbia, Canada, the study found that FRB 180916.J0158-65 signals were surprisingly regular.
For more than four days, the signal was monitored to the point that the signal would stop before each rapid eruption. Then, after 12 days of silence, the FRB signal returns.
In fact, as early as 2007, scientists became interested in FRB. As more new telescopes are put into use, astronomers have discovered a large number of FRB sources, though most of them don’t repeat them.
In 2019, CHIME teamed up to discover eight duplicate FRB burst signals and hopes to conduct a follow-up analysis of them.
As the research progresses, we hope to finally demystify FRBs, but you don’t expect them to come from extraterrestrial civilizations.
“I think we’re probably going to have a natural explanation for these events, but I think we should be open and keep an eye on the evidence,” Adam DELLer, an astrophysicist at Sweeburn University of Technology, said last year.
