Astronomers have discovered a radio burst in space which comes in a pattern, every 157 days. Astronomers have been able to find a way back to home galaxies of the Fast Radio Bursts FRBs, also known as millisecond long bursts of radio waves.
The actual cause of these bursts is still not defined. Most of the radio bursts only occur once and do not repeat. But fast repeating radio bursts end short, and may even repeat multiple times.
Some observations show that when they are in a repeated pattern, it’s sporadic or in a cluster. This year’s observation changed, when astronomers found out FRB 180916.J0158+65 occurs in a repeating pattern, every 16.35 days. It occurs for four days, releasing a radio burst every 2 hours. And it would show no movement for the next 12 days.
Now, a second similar radio burst was detected known as FRB 121102. In this pattern, it occurs for 90 days and shows no movement for the next 67 days. This occurs in every 157 days. This wave was first detected in 2016, but the information regarding its pattern was not available till 2020.
It was considered the fastest radio bursts to be traced. FRB 121102 was also linked to a dwarf galaxy, which was more than 3 billion light-years away till 2017.
The fact about FRB 121102 is that it is 10 times longer than the first one. This shows a large potential range for such an activity, the researchers said.
