We photographed impossible. Scientists from ESO in a week will show us the first photo of the black hole
The extremely sensitive event Horizon Telescope (EHT), which belongs to ESO, made the first photo, where we can see a massive black hole in the center of the Milky Way. We will see them already on April 10.
It is then at the Berlaymont Building, Brussels that a conference will be held with the participation of scientists from the European Southern Observatory, representatives of the European Commission and the European Research Council. Its main topic will be the presentation of a photo taken by EHT, which since April 2017 has been observing the space located in close proximity to the black holes we know.
Black hole immortalized in the picture
If the EHT instrument actually managed to take a picture with a black hole, it will be a very important event in the history of space exploration. Until now, we did not have any tangible proof that would undoubtedly confirm the existence of these objects in the universe.
Of course, their presence results from the assumptions of the general theory of relativity created by Einstein and the so-called indirect evidence in the form of even gravitational waves emitted during the collision of two black holes. In December 2018, four cases of gravitational waves from the star fusion of black holes were detected.
Nobody has seen the black hole in the picture yet
One of the main conditions for a detailed photo of a black hole is to have a very large telescope, for example, the size of the Earth. Of course, no one will finance the construction of apparatus of this size. As a result, the best solution was to integrate several telescopes located far away from each other. With this method, we can observe objects with much greater accuracy, having a de facto telescope with the size of the planet - says Feryal Ozel, professor of astronomy and astrophysics at the University of Arizona (USA).
This is how the Event Horizon Telescope operates, which is actually a network of several radio telescopes located in different locations on our planet. Directing them all into one observation point, we should be able to see the black hole hidden in it. At least that's what the theory says. We have to wait another week for more tangible results of this experiment.
