The black hole is in another galaxy some 55 million light years away from Earth. While astronomers have been talking about "dark stars" since 1700s, the community eventually speculated that these bright spots were in fact "black holes", with American physicist John Archibald Wheeler coming out with the term in the mid-1960s.
Scientists said the discovery "pushes the boundaries of modern science".
This is the first-ever image of a black hole.
The gravity inside of a black hole is too powerful for any light to escape past the event horizon.
The scientists said Einstein's theory predicted the shape of the shadow would be nearly a flawless circle - as it turned out to be.
Researchers claim the groundbreaking findings will help further support Einstein's Theory of Relativity, which was first announced in 1915.
Black hole has always been a subject of human curiosity. The scientists will be looking for a ring of light - disrupted matter and radiation circling at tremendous speed at the edge of the event horizon - around a region of darkness representing the actual black hole.More news: Alert over deadly fungus that thrives in hospitals

The image you see above is not an out-of-focus donut. "Something I've been working on for many, many years, trying to build a physical model of a black hole environment and predictions, and the opportunity to study the hearts of black holes is unbelievable".
EHT researchers predict that the black hole is six billion times larger than our Sun, and that it is spinning rapidly, sending subatomic particles out into the universe.
In essence, the EHT scientists photographed the shadow of the black hole cast by the accretion disc.
"The shadow of the black hole is almost circular, which is consistent with our simulations".
Scientists released the first-ever photo of a black hole on Wednesday. Once you cross the event horizon, the black hole's gravity is so strong that you can not escape it.
His team, which included graduate students, built computer simulations of the black hole to interpret some of the data the Event Horizon telescopes brought in.
