The Black Hole it is, as some of you already know very well, one of the most dangerous objects in this universe, one that many researchers struggle to study, but one that they can't really get close to. At the beginning of this year, a team of researchers announced an impressive discovery, the closest black hole to Earth, and of course that scared many people, believing that there is danger for our planet.
The Black Hole discovered by researchers then is not really a black hole, but in fact it is just a star that they identified incorrectly, and now it has been discovered how big the error was. We are talking about a very large star that can easily be misidentified as a neagram hole by scientists, because of the way it was formed, so many people understood that they should not be scared, because there is no great danger.
Black Hole: THE DANGER that SCARED a lot of people
The Black Hole the closest one to the Earth is not this star, but another one located at a much greater distance in relation to our planet, and there is no real danger for us, at least from what we have learned so far from scientists. However, the discovery of the three stars is an important one, and this is because it helped them improve the way they detect a black hole in the universe, so that they do not classify it wrongly, instead of a star or a planet.
"By making a guess at its mass, we can guess the mass of the companion mass, and it is this line of reasoning that has led astronomers to suspect that the B giant orbits a black hole. We examined the motions of the Be star by measuring the strongest emission line of the disc in the hydrogen emission. These measurements showed that the Be star displayed the same orbital period as the B giant, but with a much smaller amplitude. This suggests that the system is actually a two-star binary system. Now that our emission spectrum measurements show that the Be star orbits the B giant, then there is no room for a black hole in the HR 6819 system.”
The Black Hole it is a very difficult object to detect, and this is because it does not emit light, but swallows it, so that scientists cannot easily tell when they become visible on the images captured by telescopes. This means that it is very possible that in the future there will be an erroneous classification for another black hole, or maybe even more, but it is good that things were corrected in time by scientists, and there is no danger.
The Black Hole from the center of our galaxy is the most important in the vicinity of the Earth, but it is at such a great distance that it is impossible to be a real threat to our planet.
