“Cosmic anomaly hints at a terrifying future for the Milky Way”




Imagine a headline that says “Cosmic anomaly hints at frightening future for Milky Way”, you would immediately think that it would be a sensationalist media; but nothing to do with it, it turns out that the headline is put by the royal astronomical society of the United Kingdom and when the Royal Astronomical Society of the United Kingdom you have to read it, because there could be something very big here.


The authors of this research speak of the terrifying vision of a possible destiny for our galaxy and of something that perhaps happened in the past, perhaps the Earth was lucky in the past and other planets were not, of those billions of planets that statistically life could have arisen on them, perhaps life did not arise on so many because they suffered terrible cosmic catastrophes like this one.


This catastrophe that I am going to tell you is tremendous, it can end life in entire galaxies, the discovery was made when we saw that it was happening in another galaxy that is similar to ours, which is 1000 million light years away, but imagine, to use this simile, imagine that you are piloting a fighter plane in the Second World War along with the other planes in your squadron and suddenly the plane of one of your companions explodes, it is not your plane, it happened there several hundred meters away but obviously You deduce that the battle is beginning and that what happened to your partner may or may not happen to you.

This is the same approach of this international team of astronomers led by the Chris University of Bangalore in India. These researchers discovered that this spiral galaxy similar to the Earth located almost 1 billion light years away has a supermassive black hole with billions of times the mass of the sun. colossal because billions of solar masses is brutal, it leaves the supermassive black hole of our galaxy tiny, which only has 4.1 million solar masses, that supermassive black hole we are talking about, that other galaxy similar to the Milky Way would be hundreds of times larger.


But the extraordinary thing, what they have discovered is that this colossus is feeding monster radio jets that extend 6 million light years away, that is, the diameter above and below would be 6 million light years, is that it can engulf entire galaxies.


It is not the first energy jet of this type discovered, but this is one of the largest known in any spiral galaxy and it also changes the belief that astronomers had that galaxies like the Milky Way were stable, calm galaxies and that they did not suffer these things, they did not suffer these anomalies, now it turns out that yes, they can suffer them.




If you are inside a jet, if your planet is inside a jet that directly means death and with jets 6 million light years long, keep in mind that Andromeda is I think 1.5 light years away from us, that jet can hit entire galaxies, it can sterilize entire galaxies, this colossal jet with this power can end life in an entire galaxy.


Researchers believe that this could also have happened in the Milky Way or could happen in the near future in the Milky Way, it would not be so powerful, nor so incredibly long and it would be a shower of cosmic rays, gamma rays and


The radiation would destroy the atmospheres of any planet that passes through it, including the Earth, it would damage the DNA and increase mutation rates, if there were any living beings left after the above because if it destroys the atmosphere and that, you lose the ability to have water on the surface, for example, simply eliminating the ozone layer that would not require a jet as powerful as this would already lead to a mass extinction.




A big question is, our black hole in our Milky Way Sagittarius A* had jets of energy in the past as catastrophic as you are, I remember the mass of our supermassive black hole is 4.1 million times the mass of the sun and we do not have it millions of light years away, we have it 27,000 light years away from us, not millions of years, at the moment it is calm, but this could change, for example, if a cloud of cosmic or interstellar gas ends or a star gets too close to it, according to researchers this could trigger significant jet activity.


If an energy jet emerged from Sagittarius A*, its impact would depend on its strength, its direction and the energy production. If we are not in its sights, there would not be much of a problem, but if we are, the energy jets from the black holes come out from the poles of the black hole. It also depends on the size of the black hole and the amount of matter it is eating.
