As we all know that there is no limit of the universe, it is infinite, it is so big that as much as we try to explore it, it becomes equally big. Scientists have already discovered many things about the universe, whether it is about galaxies, stars or planets. Many famous historical events, such as Voyager 1 and Voyager 2 mission of 1977, which successfully exposed the outer space, and closely examined our solar system's giant planets such as Jupiter, Saturn, and its rings, Uranus, Neptune, and their satellites, and at the same time a beautiful photograph was taken out by Voyager 1 before leaving our solar system. And this Photograph was of our lovely planet Earth, whose name was given by a famous scientist Carl Sagan, "Pale blue dot". This Photograph was taken on February 14, 1990, by the Voyager 1 space probe from a record distance of about 6 billion kilometers. Capturing this image from such a great distance was really a great breakthrough for us.
In the same way, Apollo 8 mission of 1968 in history, who for the first time departed the low Earth orbit, reach the Moon and orbit it. Astronaut William Anders took the first image of our planet Earth from the lunar orbit on December 24, 1968, and whose official name was "The Earthrise". After looking at this unbelievable photo, the astronaut William Anders filled with emotions and said that I went in search of the moon but I accidentally discovered a new planet. At that time no one had seen our beautiful planet Earth from the space, then it was absolutely right to fall in love with this photo at first glance.
Now, in the same way, the day of April 10, 2019, has become immortalized in the history of space, because a very big breakthrough we got to experience. For the first time, we have captured the real photographs of a supermassive black hole and its shadow. Now you will think that why this is such a piece of special news? because it has so many reasons. First of all, to get a photo of a black hole, it was like taking photos of the darkness and that even without a flashlight, because even a ray of light can not escape from the black hole's gravity. So that's why a big paradox seems to be in it, at least we thought that so, before listening to this news, but don't worry, we will know how it happened.
But before further discussion, I hope you all know what a black hole really is. If not, then let me refresh your mind, a black hole is a region of spacetime exhibiting such strong gravitational effects that nothing, not even particles and electromagnetic radiation such as light can escape from inside it. Now if you know what the black hole is, then you will know that a well-known scientist Albert Einstein had a secret prediction in General Theory of relativity. He had said that in the way I am understanding the universe through my theory, there are many areas in space, whose gravity is more powerful than any other areas is still possible. But the question was how do we prove this? To prove it to all, about 200 Genius Researchers from the world were working hard for years.

| The supermassive black hole at the core of supergiant elliptical galaxy Messier 87 |
They were able to do this with the help of modern supercomputers, huge data, and Giant telescopes, named as "Event Horizon Telescope", held at eight different locations around the world. It is a large telescope array consisting of a global network of radio telescopes. But nobody knew that one day a photo will emerge from them and will become immortal forever. This huge Orange and Black Fireball is actually nothing other than a supermassive black hole. The gases and dust next to it are so huge and dense that heated up to billions of degrees Celcius and look like bright orange color, in this photo you can see it clearly. Harvard University's astrophysicist and the director of this project Sheperd Doeleman said in the excitement that we have seen what we thought was unseeable.
The photos that were taken, are of a supermassive black hole situated at the core of supergiant elliptical galaxy Messier 87 in the constellation Virgo and according to the calculation, its distance from earth is about 55 million light years and has a mass 6.5 billion times that of the Sun. In the number of science fiction movies we have seen black holes, but they are all artist creations, it was impossible for us to take pictures of the actual black hole, but now with recent pictures, it has been proved that black hole is not only Einstein's theory fantasy but a reality. With this discovery, in the coming time, more research will be done on the connection between our earth and our universe. The current images were taken from the telescope with a wavelength of 1.3 mm, and scientists aim to take it to 0.87 mm, which will give us 13 percent more accurate and clear images.
