The human eye was first illuminated by the massive black hole at the heart of the Milky Way

After years of computational detection, it was finally announced minutes ago that the Event Horizon Telescope was able to see directly the incredible massive black hole at the center of the Milky Way. . The subject is considered by scientists to be a groundbreaking discovery.

"Sagittarius A" is a black hole that scientists have long felt to be present in the heart of the Milky Way. Now the Event Horizon Telescope team has managed to cross the boundaries of its observation and capture the first image of it.

The black hole was published and inspired scientists to explore the borders of the world, and today, due to the great work in this field, another significant discovery is announced. The discovery was made possible by 300 scientists from eight telescopes around the world, and reminds us of the great things that can be done together. Advance knowledge. Scientists have always expected a supermassive black hole in the heart of the Milky Way, and decades of study and observation have shown that there is a mass 4 million times that of the Sun. So far, we have not had a direct image of this black hole, and this is the first direct image of the attractive Milky Way central black hole.

black hole is completely dark, we can not see it ourselves, but the glowing gas around it is a clear sign of its existence: a dark central region (called a shadow) surrounded by a light ring-like structure. The new view shows light curved by the powerful gravity of a black hole four million times the mass of our Sun.

Because it is about 26,000 to 27,000 light-years from Earth, it is about the size of a donut in the sky. It looks like the moon. So to capture it, the ETH team created a powerful array that connected radio observatories around the planet to form a single virtual telescope the size of Earth. The observatory observed the * Sgr A's overnight in 2017 and collected data for consecutive hours (similar to long exposure to a camera).

The Event Horizon Telescope (EHT) is a network of eight radio telescopes based in Chile, Hawaii, Antarctica and elsewhere around the world that study mostly black holes. In 2019, the collaboration similarly captured and published the first image of a black hole with the observation of Messier 87 (M87).

The Atacama Millimeter/Submillimeter Array or ALMA Observatory and the Atacama Observatory (APEX) Southern European Observatory are among the observation campaigns in the telescope program. Event horizons are involved.

According to researchers, we can now study the differences in the images recorded of the two macro-mass black holes to gain new and valuable clues as to how this important process works. We have images of two black holes that One at the top and one at the bottom is the interval for the supermassive black holes in the universe, so we can go further than ever to test how gravity behaves in these harsh environments.

Progress in EHT continues . A large observational campaign in March 2022 (April 1401) involved even more telescopes than before. The ever-expanding network of event horizon telescopes and the remarkable technological upgrades that allow scientists to capture and publish even more dramatic images as well as videos of black holes in the near future.
