Sagittarius A, the supermassive black hole.

We saw the presentation of the first image of the supermassive black hole found in the heart of our galaxy, the Milky Way, serve as a reference how important this is, that in 2020 Roger Penrose, Reinhard Genzel and Andrea Ghez received the Nobel Prize in Physics for demonstrating that in the galactic center about 27 thousand light years away there is this supermassive object with a mass of 4 million times the mass of the sun.

What we have now are precisely the first images of that monster; achieving this has not been easy at all, it has been a task of connecting various astronomical observatories around the world to create a telescope literally the size of the earth; Thanks to this coordination, we have been able to cross the veil of dust and gas that separates us from the nucleus, from the heart of our galaxy, the Milky Way, and we have been able to observe that the monster is more than 4 million times the mass of the sun.

The first image the first direct visual evidence, although in reality the black hole itself cannot be seen, it is impossible to see it, since due to its enormous gravity it swallows all the light and all the radiation, perhaps the hawking radiation but that's another matter, it swallows all the light and therefore we can't see it, but we can see its dark shadow surrounding a ring of bright and hot gas.

Some new enigmas have been revealed thanks to this image, the first data that the image offers us is the size of the shadow, the size of the shadow is proportional to the mass and it is confirmed that the mass was well calculated, it has about 4 million of solar masses as you have already said and that is in perfect agreement with Albert Einstein's theory of general relativity, therefore, a positive point for albert.

The team of astronomers who achieved this achievement using the event or event horizon telescope, had obtained in 2019 the image of a supermassive black hole, M-87, located about 55 million light years away, that is indeed a colossal monster. , about a thousand times larger than that of our galaxy, which is called Sagittarius A star, M-87 is a cosmic abyss of 3.3 billion solar masses.

There is a curious thing, another second fact that offers us the image and this time it is a mystery that needs to be explained and that at the moment astronomers do not understand why and that is that Sagittarius A star is inclined with respect to the plane of the galactic ecliptic , instead of seeing the disk of gas perpendicular to us it is tilted a bit about 30 degrees pointing almost towards us towards the earth.

We can imagine this of the ecliptic as a carousel, in fact in the solar system it also has a cryptic one where the planets move in the same plane, the sun moves along the milky way in the same plane where the most stars circling the galactic core and the planets as you can see in the image also move more or less in the same plane around the sun, curiously the sun moves around the galaxy to the galactic core in a similar way to the horse on a merry-go-round, going up and down slightly from the central plane.

The point is that the vast majority of stars are in that plane and the curious thing is that the supermassive black hole Sagittarius A is not, it is tilted with respect to that plane, it is not in the position that it should be, it does not coincide with the ecliptic of the galaxy and it is not known why, it is something strange.
