The astronomers are attempting to capture the silhouette of the black hole against this bright background provided by the swirl of gas, plasma, and other materials are that are falling inexorably into the abyss.
The news conferences are scheduled for tomorrow at 9 am.
The supermassive black hole at the center of the Milky Way, Sagittarius A*, is 26,000 light-years away and has four million times the sun's mass. In a media advisory, scientists said they will present a "groundbreaking result" from the Event Horizon Telescope project.
But how can telescopes capture the image of a Black Hole when as its concept implies it is nothing but a black hole?
What are black holes and why is it hard to see them?
The global team of over 200 globally-synched scientists, researchers and astrophysicists have not offered a peep about what will be shown on Wednesday, although they are not shy about the project and its implications.
One of the most intriguing of spacetime environments, the region around a black hole - described as the "event horizon" - is also one of the most violent in the known universe, as matter inexorably hurtling into the dark maw is mangled to what scientists guess to be the subatomic level, while light itself is rendered permanently captive, leading to the celestial singularity's picturesque name.
Microsoft Released the Windows 10 May 2019 Update to Insiders
The build is available to "seekers", meaning those in the Release Preview ring will need to manually initiate the update. The new update option will be available to all top Windows 10 versions including 1803 and 1809 starting next month.
From cheese to helicopters: United States floats tariffs on $11bn of European Union products
If the WTO approves that figure this summer, the administration will be ready to impose retaliatory tariffs immediately. Brussels countered, accusing Washington of providing Boeing with similar forms of support, including tax breaks.
Iran's Khamenei Calls US Blacklisting of Guards a 'Vicious Move'
State-owned IRAN daily went a step further, saying the USA move was a "designation of the entire Iranian nation" as terrorist. The Guards' overseas Quds forces have fought Iran's proxy wars in the region.
There is so much data being collected that the image we will see on Wednesday was actually created back in 2017. The theory was put forward in 1915, with an intent to explain the laws of gravity and their relation to other natural forces.
Interested parties can watch the Event Horizon Telescope collaboration release the first of its kind image of the black hole via a live stream that will share the long-awaited breakthrough with an eager public. Theory states that the singularity is permanently hidden from view behind the "event horizon", defined as the radius within which nothing can leave the black hole.
Scientists have observed these giants at the centre of every large galaxy, including our own, the Milky Way.
"It's a visionary project to take the first photograph of a black hole".
Alternatively, a press conference is being held by the European Commission, European Research Council, and the EHT project will also be livestreamed on the European Southern Observatory website here. Since then, telescopes in France and Greenland have been added to the network.
Astronomers have, however, been able to observe the effects a black hole has on the stars and cosmic gas clouds surrounding it. Optical telescopes are not capable of making such an observation, in part because both potential target black holes are embedded within dense thickets of dust and stars that obscure the view. If Einstein's predictions are correct, it will permit accurate measurements of the object's size and shape.
