Topic #705: Black Hole Image | the topic

On Thursday, the world saw for the first time images of Sagittarius A*, located at the center of the Milky Way, the galaxy of the Solar System. The achievement is the Event Horizon Telescope (EHT), an initiative involving hundreds of scientists from more than a dozen institutions. From 8 points on Earth, they “observe the same target at the same time and then collect all the signals,” in a “major technical challenge,” explains Taisa Storchi Bergman, head of the astrophysics research group at the Federal University of Rio. Southern Grande. In a conversation with Renata Le Bret, she said the A* images confirm the conclusions of both the 2020 Nobel Prize winners in Physics and Albert Einstein’s theory of relativity. “Massive objects appeared in the centers of galaxies,” Taissa teaches. “And they were formed with them, at the beginning of the universe.” The astrophysicist, responsible for an important discovery about black holes in the early 1990s, considers the image “a success for everyone who studies this topic.”
