While photographing the interior of a black hole is not possible, what the world could see is the image of a black hole's silhouette.
The press events are scheduled in Washington DC, Brussels, Santiago, Chile, Shanghai, Taipei, Taiwan, and Tokyo. "By getting radio telescopes around the world to work in concert like one instrument, the EHT team achieved this, decades ahead of time".
Although black holes share a key characteristic - gravitational powers beyond that of even an supervillain - they have a variety of physical appearances. Black holes have sparked imaginations for decades. A light year, which measures distance in space, equals 6 trillion miles.
A supermassive black hole with millions to billions times the mass of our sun is seen in an undated NASA artist's concept illustration.
US National Science Foundation Director France Cardova said: "This is a huge day in astrophysics". "We're seeing the unseeable". Black holes pull in anything nearby with unfathomable force and gravity, even pulling in light.More news: Israeli election on course for dead heat
Doeleman said the image could have been just a blob, but they were thrilled to have captured the donut-like appearance of the accretion disk surrounding the black hole's shadow.
The circular nature of the black hole in the image also helps confirm Einstein's theory of general relativity, which predicted that shape.
Broderick said that the image proves that supermassive black holes are "analogous in important ways" to smaller black holes, which are better understood by scientists.
"Science fiction has become science fact", University of Arizona astronomy professor Daniel Marrone said.
"The EHT will continue to evolve in the coming years, notably with the addition of two new telescopes: the NOEMA telescope in the French Alps, and the Greenland Telescope". The global network has essentially created a planet-sized observational dish.
Astronomers believe that images of Sagittarius A, which is a black hole at the centre of the Milky Way, will show a lopsided ring of brightness due to the gravity bending light closer to the black hole. Scientists predict that the hole is approximately 53 million light-years away from Earth.
