How Did scientist manage to get the image of Black Hole

Black hole are one of the mysterious place and always curious subject for the astronomers. All we have heard the news that scientists have captured the image of black hole, previously which thought to be impossible, as we know even light cannot escape from black hole. But if it is so then how scientist manged to get the image of such a giant, distant and mysterious object in our universe, you may also have a curious ant biting in your intellect that how they did this.

 The science used behind capturing the silhouette of black hole is very interesting, atronomers told that as the black hole whom we just used to imagine only, is very far and if we try to capture the image by using telescope, then we need larger aperture of telescope so that it can capture enough light and the size needed will be of approx to the Earth's size,  but it can't be possible to have such a giant telescope.

 So to get the more light and capture the image, scientist after improving, employed the technique which is used to see far distant object that is VBLI. Using the array of small and large telescope available at different places in the world and synchronising them, so that they can capture the large no. of different data and after combining that huge amount of data which is in Petra byte scientist manged to have image in which light swing around a dark and densed object.

 The image of black hole is the magic of physics and computer science, where physics is used to capture the large no. of data and computer science is used to arranged and combine and process the huge amount of data. It was like a big image puzzle in which a large no. of parts and they have to get arranged to get the image. Scientist synchronised all the telescope placed at different places , and as the earth rotates they capture light and collect the data
