Mysterious radio signals from space hit earth every 16 days

136

Scientists are studying what they term as constant and “fast radio bursts” (FRBs) coming from a galactic system a billion and a half light years away from earth. Radio signals are commonly detected by our terrestrial radio satellites, and most of them are from collisions of neutrons in space. FRB’s send out short, energetic radio waves multiple times and usually, its sporadic or in a cluster.

Canadian astronomers working for Canadian Hydrogen Intensity Mapping Experiment/Fast Radio Burst Project Collaboration however, detected an anomaly. Between September 16, 2018 and October 30, 2019, FRB’s from this location termed as 180916.J0158+65 created a pattern of bursts occurring every 16.35 days. Over the course of 4 days, the radio signal releases a burst or two every hour, and then, it would go silent for another 12 days. The repeating signal was traced to a massive spiral galaxy around 500 million light-years away.
