Finally – The First Image Of The Black Hole
The Event Horizon Telescope (EHT) – a planetary scale based array of 8 different types of telescopes was used to capture the first image of the black hole. The image was released to public by the EHT team on 10 April 2019 in a press conference at 6:30 IST unveiling the first direct visual evidence of a Super Massive Black Hole and its shadow. The image reveals the super massive black hole present in the center of Messier M87 Galaxy, a massive galaxy in the nearby Virgo Supercluster.
Here is the image which humanity want to see since long time .

This black hole is located at a distance of 55 million light years away from Earth and is 100 billion billion Kms long.
So, How They Find It?
The EHT works by linking a total of 8 telescopes around the world thereby making a virtual telescope the size of the earth . These telescopes were pointed towards the center of super massive black hole of galaxy M87 present in the Virgo Supercluster.
Through years of international collaboration with a total of 200 scientists worldwide and sincere hard work, humanity has obtained the first image of the black hole which till now had evidence only on the basis of the observation of the stars present around the centers of galaxies and mathematical model as presented by the general theory of relativity. The image provides seeming insights and paves the way for a a lot of research in the field of astrophysics as well as cosmology.
The newly published image of the super massive black hole M87 has answered one of the most fundamental questions of all in the field of physics. Is Einsteins theory of general relativity valid near the black hole also? After the image was published, the answer is clear. The Einsteins theory of general relativity is valid even at the black hole where the most harsh environment of the universe is known to exist. Therefore, the theory of relativity has passed its final test.
We have taken the first picture of a black hole,” said EHT project director of the Center for Astrophysics | Harvard & Smithsonian | Sheperd S Doeleman – “This is an extraordinary scientific feat accomplished by a team of more than 200 researchers.”
Black holes are extraordinary cosmic objects with enormous masses but extremely compact sizes. The presence of these objects affects their environment in extreme ways, warping space time and super-heating any surrounding material.

“You have probably seen many, many images of black holes before,” said Heino Falcke, a professor in the Netherlands who chairs the EHT Science Council. “But they were all simulations or animations. And this (image) is precious to all of us, because this one is finally real.”
Now here we see the 2 the image of the black hole we have obtained recently and that predicted by the mathematical models –
Here we can see the similarities between both of the images.
The image data was taken back in 2017 but it has taken scientists two years to process the whole data and publish an image with the help of it. The data was equivalent to 5 petabytes (5242880 gigabytes) which was necessary to create the image of the black hole. The algorithm which helped process the image of the black hole was designed by Kate Bowman which she started designing when she was a MIT graduate.
The answers that this image will unveil
- It will help in the discovery of the Quantum Theory Of Gravity.
- It will answer some unsolved mysteries as whether the Dark Matter is responsible for making the black hole supermassive.
- Whether Time Travel is possible or not inside a black hole.
- Most importantly verification of GTR which has already been given.
