Hundreds of scientists and researchers and eight telescopes participated in the work to disseminate the image.
For the first time in history, the image of a black hole is disclosed.
The April 10 will not be forgotten anytime soon to world science. For the first time, it was possible to observe the photo of a black hole, an invisible phenomenon in which the force of gravity exerts a pressure that leaves nothing around to escape.
Astronomers had not yet been able to grasp precisely the image, so the phenomenon was known only in illustrations, artistic conceptions, and simulations.
The announcement was explained at an international conference, accompanied live by several countries.
Hundreds of scientists and researchers and eight telescopes participated in the work to spread the image and was the fruit of the dream of Albert Einstein 100 years ago.
The live broadcast began 15 minutes before the image was announced.
The first to speak was Carlos Moedas, of the European Research Council, who was very moved. “Einstein could not imagine what he discovered… To take a picture of something a man dreamed of 100 years ago, you need people from 40 countries. If there is a great moment for all of us, it is today,” he said.
“Even a child knows what a black hole is, and the best description came from a child – it’s just a hole you can not fill,” says Luciano Rezzolla of Goethe University Frankfurt. “You may wonder, how do you know it’s a black hole? The answer is that it fits in nicely with what we anticipated in theory.”
Eduardo Ros, of the University of Granada, went on stage to tell how the observations were made using telescopes where the atmosphere is excellent and dry to avoid atmospheric interference.
So they had to pay close attention to the weather and be ready to receive short-term observations. The hard disks of the Antarctic telescope had to be stored during the winter because an airplane could not quickly get in and out to carry the data.
Then Monika Moscibrodzka of Radboud University explained what they learned over four days of observation when the ring did not change in size and did not go away.
“It means that it is likely to be a permanent object. The change in ring light – brighter at the front – indicates rotation, the image is still not clear enough to measure the rotation, but we know that it occurs clockwise,” he said.
Katie Bouman: Meet the person responsible for the first image of a black hole

On the last Wednesday (10), the first image of a black hole was disclosed. The event, widely commented around the world, is the result of the work of the Project Event Horizon Telescope and also of a scientist: Katie Bouman.
She was responsible for creating an algorithm capable of understanding thousands of astronomical data and, with the help of her team, deciphering what they call “invisible.”
The first time Bouman saw the startling image of the black hole was in June of last year. Since then, she has kept secret the ultra-secret project she has participated in. “We all watched the images appear on our computers,” Bouman said. “The ring [of the black hole] came so easily. It was unbelievable. ”
The photo of Bouman smiling and sitting in front of the computer, with the image of the black hole in the background, was very shared in the social networks. In a posting on her Facebook, she wrote, “Noting, incredulous, the first image I ever made of a black hole while it was in the process of rebuilding.”
In addition to Bouman, other women also worked on the Event Horizon Telescope, however, most of their colleagues were men. Even during the official announcement of the image, last Wednesday, only men were present on the stage.
The project the scientist participated in has grouped specialists from various fields, such as physicists and mathematicians. According to TIME magazine, Bouman’s background is in computer science and electrical engineering, and when she joined the team six years ago, she had never worked with black holes.
On the lack of women in science, Bouman says he thinks about it. “How can we involve more women?” She asks. “One key is to show that when you enter fields like computer science and engineering, it’s not just sitting in a lab, setting up a circuit or typing on your computer.”
Bouman plans to continue working on the project. According to her, in the future, the team could produce black hole films as well as static images.
