The first time I took a picture of a black hole three million times bigger than Earth

Images of black holes are also announced in Tokyo (Japan), Brussels (Belgium), Taipei (Taiwan), Santiago (Chile) and Shanghai (China).

10 pm at 10 pm Vietnamese time, the US National Science Foundation announced "breakthrough results from the Event Horizon Telescope project".

"We have done what many people think is impossible. By capturing the shadow of the black hole , it proves to the point that there are many invisible, mysterious entities that really exist." Dr. Ziri Younsi, of the Muller UCL Space Science Laboratory, is part of the ETH project.

"This result will lay the foundation for many future studies. Black holes can play an important role in human understanding when studying the behavior of light and matter in harsh environments. most in the universe " , he continued.

This black hole is 40 billion kilometers in diameter, three million times bigger than the Earth and is several trillion kilometers away from us . Jessica Dempsey, deputy director of the East Asia Observatory in Hawaii, said that when she first saw the black hole taken two years ago, it reminded her of Sauron's eyes in the movie " The Lord of the Rings".

The image shows a black hole in the center of Messier 87, a giant galaxy in Virgo galaxy cluster.Scientists also said that what they found coincided with Einstein's general theory of relativity.

Event Horizon is an international collaborative scientific research project, conducted in 2012 to observe the supermassive black holes located in the center of galaxies, namely the Sagittarius A * super-black hole in the center of our Milky Way galaxy and M87 belong to the Super Virgo A.

Humans have never seen the black hole with their eyes because it absorbs all the light around it. Therefore, the only way to discover black holes is to study the space around them.

The Event Horizon program uses very long baseline interference techniques (Very Long Baseline Interferometry, VLBI) by combining radio telescopes around the world.

In particular, many independent antennas located tens of thousands of kilometers away are coordinated, observing and recording data at the same time, forming a giant telescope network with a diameter equivalent to the left diameter. land.

This virtual telescope increases angular resolution enough to observe the large structure of the area surrounding the event horizon.The event horizon is the inner boundary of space-time near a singular point, all kinds of matter that lie below this limit, including electromagnetic waves (including light) cannot go beyond to come to the observer.

Event Horizon is expected to test Einstein's general theory of relativity, when he discovers deviations under the strong gravitational influence of a black hole. There is also a study of accretion plates and rays emitted from the black hole, discussing the existence of event horizons and developing a physical base for black holes. Previously, images of black holes were often simulated by supercomputers and 3D algorithms.

Previously, the nature of black holes also did not have a common voice among related sciences such as optical physics, quantum physics and of course astrophysics. Each major approaches the problem with its own specific theoretical concepts.

Be aware, these imminent images will not indicate what people are curious about the center of the black hole, because all the light will be swallowed by the black hole itself. Instead, what we see is the event horizon that surrounds it, the mysterious point at which time and space rules are deformed.

The international team of more than 200 global scientists and astrophysicists has agreed to keep all research results confidential until April 10.
