The "groundbreaking result from the Event Horizon Telescope (EHT) project", will be delivered in an announcement by the US National Science Foundation on Wednesday, April 10, at 9am EDT (13:00 GMT).
The second - called M87 - resides at the center of the neighboring Virgo A galaxy, boasting a mass 3.5 billion times that of the sun and located 54 million light-years away from Earth. However, matter and energy aggregate around the edge of a black hole, known as the event horizon.
Scientists will be "staring down the pipes of eternity" if, as expected, the first image of a black hole is released this week..
A black hole is a celestial object that compresses a huge mass into an extremely small space.
The news, said to be "ground-breaking", will be announced at six simultaneous press conferences around the world.
In their attempt to capture an image of a black hole, scientists combined the power of eight radio telescopes around the world using Very-Long-Baseline-Interferometry, according to the European Southern Observatory, which is part of the EHT.
A black hole's event horizon, one of the most violent places in the universe, is the point of no return beyond which anything - stars, planets, gas, dust, all forms of electromagnetic radiation including light - gets sucked in irretrievably. However, a black hole that is located within the crowded centre of a galaxy draws matter toward itself.
There is so much data being collected that the image we will see on Wednesday was actually created back in 2017. Since then, telescopes in France and Greenland have been added to the network. More than 100 years ago, Einstein's equations predicted exactly what the size and shape of a black hole's shadow would be.
Beyond the historical implications of such an achievement, imaging a black hole's event horizon will also put Einstein's theory of general relativity to its ultimate test. The coordinated observations were also made in X- and Gamma-rays.
Dr. Urry pointed out that evidence for the existence of black holes has mounted steadily since the 1960s, including the Nobel Prize-winning detection, in 2015, of vibrations in spacetime from two colliding black holes by the LIGO experiment.
"What the black hole image could do for us, if we can get it, would be to take something that is the most extreme, the strangest prediction of general relativity, one of the great accomplishments of the human mind, [and] combine it with the most advanced electronics with a planetary scale collaboration with the most advanced statistics [and] new imaging techniques", Peter Galison, a professor at Harvard University and EHT collaborator, said at SXSW.
"This kind of light can not be seen with human eyes".
The news conferences are scheduled for tomorrow at 9 am.
