Mysterious signal for the Earth-
So basically, according to the scientists, recently they have discovered that the first radio which has actually beaten at a constant rhythm but now it is making a mysterious indication which is according to the scientists, coming from the outskirts of another galaxy.
According to the latest study, that mysterious radio signal is actually located in a galaxy, which is basically 500 million light-years away from the Earth. And most importantly, this is actually the first time that scientists have surely observed periodicity in these coming signals.
They are actually now known as the fast radio bursts, which are short for FRBs.
What is FRBs –
FRBs are actually one of the most tantalizing and confusing puzzles that this universe possesses and thrown at scientists in the past few years. At first, which was actually spotted in 2007.
These powerful radio flares are created by energetic sources, but this is still not clear what they are made up of. The team who are searching on this has made a statement in front of media; they said that“We conclude that this is the first detected periodicity of any kind in an FRB source.
The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object.
The team of FRB has actually been keeping tracks on the repeating burst, which is actually between September 2018 and October 2019. They were basically using the CHIME radio telescope in British Columbia.
At that time, the bursts were actually clustered into a period of four days, and then, later on, it seemed to switch off for the next 12 days. The cycle was actually about 16 days.
Some of these cycles did not generate any kind of visible bursts, but apparently, those made that they were all synced up to the same 16 days of intervals as expected.
