First view of a black hole in the center of the Milky Way captured with the Event Horizon telescope

During historical development, astronomers released the first image of a black hole in the center of the Milky Way galaxy. Black Hole Sagittarius A *, 4 million times the mass of the sun, is 25,000 light-years from Earth.

In the Official Journal, the European Southern Observatory (ESO) revealed that the image was created using the Global Horizon Telescope (EHT) Collaboration, a global telescope network.

Introducing the supermassive black hole

The tremendous development has shown direct evidence that there is a supermassive black hole in the center of the Milky Way galaxy. Due to its astounding distance from the Earth, it appears to be about the same size in the sky as the donuts on the Moon.

Astronomers have portrayed it as a combination of eight existing radio observatories around the planet to form one Earth-sized virtual telescope.

Geoffrey Bower, a researcher at the EHT project, said in a statement: “We were amazed at how the size of the ring matched Einstein’s general theory of relativity. These unprecedented observations have greatly improved our understanding of what is going on in the very center of our galaxy. and offers new insights into how these giant black holes interact with the environment.

It is noteworthy that the collaboration brought together 300 researchers from 80 institutes around the world. At a press conference held to publicize the image, astronomers explained that the supermassive black hole in the Milky Way looks very similar to the first black hole photographed in the galaxy Messier 87 (M87).

According to experts, the supermassive black hole is significantly smaller than in the M87 galaxy. By comparison, if Sagittarius A * is the size of a donut, the M87 black hole is the size of a football stadium.

EHT researcher Keiichi Asada said: “We can now explore the differences between these two supermassive black holes to get valuable new insights into how this important process works.”

“We have images of two black holes, one at the big and small end of the supermassive black holes in the Universe, so we can study much more how gravity behaves in these extreme environments than ever before,” he said. added.

M87 is about 55 million light-years from Earth and is 6.5 billion times the mass of the sun.
