Since 2017, the Event Horizon Telescope Collaboration (EHT) has been studying two supermassive black holes, one located at the center of the Milky Way, called Sagittarius A*, the other found at the core of the supergiant elliptical galaxy Messier 87.
Astronomers have announced that they will reveal the first-ever photographic image of a black hole on Wednesday.
Sagittarius A* is measured as being some 26,000 light years from Earth and massing approximately 4 million times that of our sun.

Although black holes have been depicted in film and television works such as the 2014 movie "Interstellar", their true appearances are still a mystery.
During a press conference at last month's South by Southwest (SXSW) festival in Austin, Texas, Sheperd Doeleman, who is the director of the Event Horizon Telescope, shared a quirky anecdote so people could relate to the kind of challenges involved in this project.
NASA said: "Scientists can study stars to find out if they are flying around, or orbiting, a black hole". Using a technique called Very Long Baseline Interferometry, or VLBI, the instruments of all these observatories located thousands of miles from one another were linked to form a "virtual telescope", whose resolving power is as big as the space between the disparate dishes.Читайте также: Oxford University to rethink degree given to Brunei sultan
The event horizon is a point of no return within a black hole, where the effects of gravity are simply too strong to escape.
The new observations will be used to detect evidence of what happens at the edge, or shadow, of a black hole.
The team is hoping to produce a groundbreaking image and determine whether Einstein was right when he predicted the exact size and shape of the black hole's shadow back in the early 20th century.
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.
Einstein's theory, if correct, should allow for an extremely accurate prediction of the size and shape of a black hole.
Exciting news, definitely, but now we can't get the Muse song out of our heads.
Wednesday's announcement is scheduled for 9 a.m. EDT.
The U.S. National Science Foundation, which will host the event in Washington D.C., said the announcement was a "groundbreaking result".При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
