Scientists discovered Sagittarius A* as early as 1974. Years of observation allowed the object within it to be identified Milky Way As a black hole it swallows everything in its range. Visual confirmation of notes appears Globalism On Thursday, May 12, 2022, when her photo was shown.
Sagittarius A * the black hole in the image
The picture was shown at press conferences organized simultaneously around the world. An international team called the Event Horizont Telescop (EHT) was responsible for the preparations. To make or to invent picture The data provided by radio telescopes from around the world were used (you can see their location in the photo in the article gallery). Photography Black hole It was very demanding, because there are 27 thousand. Light years from Earth. Astronomers compare its size in the sky to the size of a “cake on the moon”.

Scientists report that the shape of Sagittarius A* is the first visible and “conclusive” evidence of the presence of a black hole in the center of the Milky Way. consequences The EHT team was published Thursday in a special issue of “The Astrophysical Journal Letters.”
The black hole itself is not visible in the image, because it is quite dark by nature. picture However, it does show gases shining around it, a feature of black holes – the invisible black center is surrounded by a shiny circular structure. Sagittarius A* is 4 million times larger than the sunPhotography shows light is bent by the black hole’s strong gravitational pull.
We were amazed at how exactly the ring size matched the predictions of Einstein’s general relativity
Jeffrey Bauer, scientist on the EHT team said.
These unprecedented observations have expanded our understanding of what is happening at the heart of our galaxy. Thanks to this, we can also better study how these giant black holes interact with the environment
– added the world.
The second image is only of a black hole
While black holes have been known to astronomers for decades, Sagittarus A* is the second object to be converted into an image. The first image was also developed by the Event Horizon Telescope team. The black hole of the galaxy M87, 55 million light-years from Earth.
