Knowing just a year ago, on the eve of what may be the scientific achievement of the century, there may have been, it was nail biting to the astronomers. They would, for the first time, a picture of a black hole, it is one of the most fascinating phenomena in the cosmos? The image that followed, the breakthrough of the year by 2019. This is why it is a (very blurry) photos, which are also compared with the ‘eye of Sauron’, as much as it meant for the stars, and what we have learned about black holes at their centers.
This is some of what we know about black holes and dark matter before it, the international research team behind the Event Horizon Telescope Project (THE) in the first image, on 10 april 2019 at the latest, unveiled by a black hole is a region in the celestial space, where gravity is so strong that nothing can get out, escape, not even light. There are only a few phenomena are as abstract as a black hole, because no matter how you perceive it and that no light transmits or is reflected?
Messier 87 (M87), the black hole that was eventually chosen, and a sample well of 6.5 billion, is twice as heavy as our sun. It is as much as 50 to 55 million light-years away from our hotel. There’s a picture of it comes down to it, taking pictures of a grain of mustard seed, in the Washington, D.C., from Brussels, as did the astronomers of THE project. Second, a comparison that speaks to the imagination: at a café in Paris, a newspaper in New York to read it.
is No single telescope that is high enough to make such a picture. For this reason, the Event Horizon Telescope Project (THE) has been set up an international network of eight radio telescopes on four continents, and more than 200 people from at least 18 countries. The network of telescopes which, through atomic clocks are tuned to each other was – it was large enough to allow for the radio emission of M87, the best of the black hole, it has to be picked up. In the end, the various images are collected, and the layers are merged.

what is The result? A picture of a black empty space where a bright ring composed of photons, or particles of light, which is due to the strong force of gravity in an orbit around the hole is forced to be lit up. The photo was taken at the press conferences in six different cities and towns was proposed, which also include Brussels, belgium.
From Brussels: “Finally! No more simulations. You are looking for the very first time at a real ” black hole.” #EHTblackhole #realblackhole #blackholecam pic.twitter.com/HH3m4v3fHH

The orange is the color of the ring should not be taken literally. The image is derived from radio frequency signals: they can hear you, but you can’t see. The frequency of the radio signal by an international research team, translated into images. Also, it was not the orange, but the blue tinge had been. “We have opted for an orange glow all around it, the black hole is very hot,” explained the American astrophysicist, Sera Markoff, from. She has been a professor of astrophysics at the University of Amsterdam and a member of the Event Horizon Telescope team.
in any case, the bottom portion of the ring in a suit, brighter than the rest. That’s why the astronomers, that is, the material that emits radio waves, with a speed of up to us moving. This would mean that the black hole spins.And Einstein’s theory of relativity the existence of black holes, predicted, and was once again, proven to be.

A black hole is what is left after the explosion of a star, a star that is more massive than the sun. During this explosion, producing a star for a moment the amount of light as a whole galaxy to which it belongs. And then for ever to be black. It was a black hole for the 1964 and ‘frozen stars’ as they are called. Further, it is at the core of the explosion is so dense that a black hole is formed. Since there is no black hole can escape – there can be only raids – they grow over time into the ground. For instance, in september, 2019 is not yet a star, which by a supermassive black hole in bits and pieces, it was torn up.
Black holes may be waking up as
The above is about M87, the black hole in the constellation Virgo, 50 million light-years away from us. Originally, there were two candidates: M87, and Sagittarius A* (Sgr A*, the black hole, which is located in the center of our galaxy and is “only” to 26 000 light-years away. The astronomers showed that, ultimately, only the image of the Messier 87, with the condition that the image of the black hole in our galaxy are still to come.
A second shot followed, for the moment,but it was recently revealed that Sgr A* is awake and seems to be up.Although Sgr A* is normally a very quiet, behave, are the bright bursts, since 2014 has increased. That said, a research team led by French and Belgian scientists. This is why, it is as yet unknown.
