This fast radio burst is the strangest thing discovered so far

Since observing the first of them, it has been fast radio blasts — they fast radio bursts Or FRB, as the English say – never stop intrigue Astronomy scientists. It usually lasts a few thousandths of a second. Researchers are still struggling to explain the exact origin. Especially since they just discovered a new and strange case. FRB 20191221A. a Radio blast which runs three seconds. Consists of Blinks of radio waves that repeat every 0.2 seconds. With tachycardia!

This FRB source is located in a galaxy several billion light years from Earth. Researchers believe it may have come from a magnetica fairly rare form of neutron star known to emit strictly periodic signals.

The first truly cyclical fast radio burst

Remember that most of the fast radio bursts that researchers have observed so far flash for a few milliseconds before disappearing. However, some of them appear to be cyclical. It flashes randomly for a few days. Then he stopped. before resuming broadcasting. But FRB 20191221A is the first to be truly cyclic.

something to think about pulsar And to the magnetic stars that emit radio flashes in Milky Way. or almost. Because FRB 20191221A is a million times brighter! Possibly due to a mechanism or event that caused the flashes to be extremely bright for three seconds. Just when astronomers were straining their ears. To find out more, researchers will need more observations about the new FRB. And others who will enrich their understanding of the phenomenon.
