Astronomers have detected another fast radio burst over a period of 157 days. Astronomers are expecting to unearth some clue about the mysterious phenomena in deep space.

First, the Fast Radio Bursts were spotted in 2007. This bursts remain mysterious to date, arising potential causes range from advanced alien civilizations to merging of superdense neutron stars.

More than 100 FRBs have been discovered to date, but no repeated activity has been discovered. Since January of this year, astronomers have continuously detected fast radio bursts of the class known to be FRB 180916.J0158+65.

FRB 180916.J0158+65 seems to exhibit a cycle of 16 days in which it fires off bursts for a 4-day stretch, goes off for 12 days and then starts all over again. Before this, spotted FRB 180916 to have erupted in such a periodic way, but now they have found this one too.

Astronomers monitored the repeater FRB 121102 using Lovell Telescope, a radio dish of 76 metres at Jodrell Bank Observatory, England. They have collected data which indicates the 157-day activity cycle with 90 days of firing up and the other 67 days going off.

The study co-author, Duncan Lorimer, the associate dean for research at West Virginia University, said in a statement said, “This exciting discovery highlights how little we know about the origin of FRBs. Further observations of a larger number of FRBs will be needed in order to obtain a clearer picture about these periodic sources and elucidate their origin.”

Other Studies

Also, Kaustubh Rajwade of the University of Manchester, England conducted a study which was later published in the journal Monthly Notices of the Royal Astronomical Society. This paper talks about the repeated behaviour of FRB 121102. This paper also says, “If the period is real, it shows that repeating FRBs can have a large range in their activity periods that might be difficult to reconcile with neutron star precession models.
