What does a black hole look like? We're about to find out

That means the image shows what the black hole looked like that many years ago.

The event horizon is the boundary of a black hole from which even light can not escape.

Black holes, phenomenally dense celestial entities, are extraordinarily hard to observe by their very nature despite their great mass. Fortunately, our galaxy's supermassive black hole is on the quiet side. In the optical range, the ring around the black hole would likely appear white, perhaps tinged with blue or red, according to Fox. This black hole is about 6 billion times the mass of our sun.

But scientists say they were able to produce the new image from data collected from a series of radio telescopes around the world. This monumental feat has been made possible by EHT's eight ground-based radio telescopes positioned throughout the world, coming together in an global collaboration.

"Black holes are the most mysterious objects in the Universe", Doeleman said during the press conference at the National Press Club in Washington, D.C. Most galaxies are thought to have a supermassive black hole at their center.

The galaxy is called Messier 87, or M87. "Once you cross it, you will never be able to get out and you will never be able to communicate", said astronomer Avi Loeb, who is director of the Black Hole Initiative at Harvard but was not involved in the discovery. It's believed that what we see on the image is the black hole surrounded by a ring, or "halo" of luminous gas. It is more than six times bigger than the sun.

Using 8 extremely powerful radio-telescopes, set up on 5 continents, numerous specialists and having processed hundreds of gigabytes of data, the humanity snapped a very important shot.




As is well documented in today's announcement, it took a remarkable effort and coordination from scientists and organizations around the world to even have a chance to make this happen.

The team's observations strongly validated the theory of general relativity proposed in 1915 by Einstein, the famed theoretical physicist, to explain the laws of gravity and their relation to other natural forces.

And in an incredibly amazing twist of events, the black hole discovery appears to confirm the theory of relativity proposed by Albert Einstein a century ago.

Einstein's theory also was validated by another major astrophysics achievement announced in 2016, the detection of gravitational waves, or ripples in spacetime, arising from two black holes that smashed together. "Einstein, we rejoice in your brilliance". He added that he felt very satisfied that the image did not contain any big surprises. "It's nearly humbling in a certain way", said Shep Doeleman, the project's director. We saw something so true.

If you didn't know what you were looking at, the image wouldn't really be that interesting.

Until now it was impossible to tell which was right, but the image that was released on Wednesday was totally consistent with Einstein's predictions: Another score for the great man.

There has been incredibly strong evidence that black holes exist for a long time, but this still isn't the same as directly observing the thing itself - which is what we have the privilege of doing now.
