To solve the mystery behind the fast radio burst (FRB), the team analyzed years of data and predicted that the next round of activity would break out around August. < / P > < p > FRBS are pulses of radio signals, usually releasing incredible energy in milliseconds per event. At present, scientists have found a few repeat FRBS, or at least we think they are random repeats. < / P > < p > earlier this year, astronomers discovered a periodic FRB model hidden in FRB 121102. Through the analysis of 32 FRBS in the past four years, we can see that it follows a cycle of about 157 days – an active period of 90 days, and then keep silent for 67 days. < / P > < p > in May, the researchers introduced FRB 121102 in the previous article. At that time, they predicted that the next active event would be between June 2 and August 28, 2020. If not, FRB 121102 will come as agreed. It is reported that astronomers use the domestic 500 meter aperture spherical radio telescope (fast) to observe the position of the signal source from March to August. It was not until August 17 that FRB 121102 achieved at least 12 outbreaks in two hours before it was successfully captured by the research team. < p > < p > unfortunately, although it has been confirmed that FRB 121102 does occur periodically, the exact details of its compliance are still unknown. After merging data from multiple studies, the team locked the actual running window to 156.1 days, with the signal source active for 99 days. < p > < p > according to this new schedule, FRB 121102 may fall into silence again from August 31 to September 9. If there is an explosion after that, it means that the period of the signal source has begun to change, or people have not uncovered its true veil. In addition, other scientists have given different conclusions on the cycle of FRB 121102. For example, the research team led by Marilyn cruces of the Max Planck Institute estimated that the period would be about 161 days. Global Tech
