The first image of the mysterious black hole is finally here

The first image ever seen of a black hole.

Using a global network of telescopes to see "the unseeable", an worldwide scientific team on Wednesday announced a milestone in astrophysics - the first-ever photo of a black hole - in an achievement that validated a pillar of science put forward by Albert Einstein more than a century ago. Many marveled at how much the film's rendering of a black hole called Gargantua resembled the image released on Wednesday.

The image shows a ring of fiery light surrounding a black circle. In a post by the lead singer of popular Taiwanese rock band Mayday, the black hole was turned into the surprised face of a feline.

To get an image of a faraway black hole, scientists had to get eight radio telescopes on several continents, including Antarctica, to look at the same place at the same time.

To complement the EHT measurements, NASA's Chandra, NuSTAR and Swift space telescopes participated in the observing campaign.

The telescope data was gathered two years ago, over four days when the weather had to be just right all around the world.

Strictly speaking, the graphic released is not a photograph of a black hole.

As researchers explained, while the black hole itself cannot be seen because no light could escape its gravity, one can see a black hole's shadow produced by the event horizon. He's a black hole, ' she wrote. "I see now, cats are the essence of the universe", one user commented below the post, which has been shared over 18,000 times.

The first test of strong gravity was the Laser Interferometer Gravitational-Wave Observatory's (LIGO) observation of gravitational radiation from two colliding and merging black holes.

Yet many on Twitter couldn't help but see their favorite ring-shaped food in the image. You have to eliminate time and space and light.

With a sense of excitement, I watched the livestream showing the image of the black hole from the centre of M87 for the first time. This shadow is what the EHT image reveals.

The fact that black holes do not allow light to escape makes viewing them hard. The volume of a sphere (assuming its density doesn't change) is proportional to the cube root of its mass: double its mass and it only increases in size by 26 percent.

Black holes, phenomenally dense celestial entities, are extraordinarily hard to observe by their very nature despite their great mass. Data from EHT confirmed this hypothesis and thus another aspect of general relativity. Both black holes, which might be shown on Wednesday fall into the latter category. The idea has been debated, refined and expanded upon for more than a century. That will allow scientists to capture an even sharper view of M87 but also other objects. Direct evidence was not acquired until the 2015 detection of gravitational waves.

The black hole in M87 isn't the closest to Earth, but it's among the biggest, which made it a very promising target for the EHT, Derek Fox, an associate professor in the Department of Astronomy and Astrophysics at Penn State University, told Live Science (Fox was not affiliated with the EHT discovery).

Perhaps most notably, the Interstellar black hole has a thin streak of matter around its centre, which M87's black hole seems to lack. They are believed to be formed by collapsed stars.
