A black hole at the center of our Milky Way galaxy has anomalous activity that scientists still can't explain

While studying the black hole Sagittarius A *, located in the very center of our Milky Way galaxy, scientists discovered anomalous activity, which manifested itself in the form of irregular outbreaks over a fairly long period. It is about this discovery and its study that will be discussed in this material.

Supermassive black hole and its inexplicable pulsation

Located in the very center of the Milky Way, a supermassive black hole called Sagittarius A* acts as a source of radio, X-ray, and gamma radiation.

And as it turned out, Sagittarius A * daily abruptly increases its activity and emits in ambient radiation, which exceeds its usual level by intensity from 10 to 100 times.

Scientists became interested in this phenomenon, and it was decided to perform a thorough analysis of the data collected by the Swift space observatory over a fifteen-year period.

So it turned out that a high level of intensity in a supermassive black hole was observed in the period from 2006 to 2008. Then came the so-called "period of silence", which lasted four years until 2012. Then the intensity of the outbreaks again increased greatly.

To date, astronomers have not identified any significant patterns in these outbreaks. They will continue their observations in the hope of finding an explanation for this phenomenon.

Now scientists are trying to establish whether gas clouds passing in relative proximity or stars have anything to do with periodic bursts of radiation. Or, nevertheless, the clue to the phenomenon of periodic powerful outbursts of the supermassive black hole Sagittarius A * should be sought in a completely different place.

The scientists shared the results of the work already done on the pages of the Monthly Notices of the Royal Astronomical Society.

Well, let's wait for scientists to solve this riddle. In the meantime, if you liked the material, then do not forget to rate it, and also subscribe to the channel.
