First black hole observed by mankind

The Event Horizon Telescope project, which aims to identify black holes directly, has released a black hole that was captured for the first time in a simultaneous press conference held in six countries around the world.

The black hole has strong gravity, and it has been thought that it can not escape even the light so that it can not be seen. The photo released this time is a black hole project that says that the center is black, the inside is empty, and the light can not escape. This achievement was published in The Astrophysical Journal Letters in six papers.

The project combines eight radio telescopes around the world and uses them as earth-sized telescopes. This super-sized telescope has a resolution of 2,000 times that of the Hubble Space Telescope, and is capable of counting the number of seam balls on the other side of 13,000km. This telescope is an average of 1PB per night, so over 1,000TB massive observational data is integrated and processed. The project was based on the M87, a galaxy of the elliptical galaxy of the Virgo cluster, which was supposed to have an eventful Horizon telescope and an extraordinary mass black hole.

This extravagant black hole is located 55 million light years from Earth, and its mass is about 6.5 billion times that of the sun. Einstein ‘s general theory of relativity predicted the most extreme astronomical object in the universe, and the compact, massive mass produced strong gravity, distorting the surrounding space and overheating surrounding matter.

Therefore, if there was a glowing gas around the black hole, the black hole in the center would look like a black shadow. But in the interview, the black circles in the center of the image are said to be the shadow of a black hole that light can not pass through, not the event horizon of a black hole.

Also, this observation does not allow us to observe the jet that a black hole emits rapidly. If a jet is identified, it affects the galaxy and understanding of the jet can lead to an understanding of the entire galaxy. This will be analyzed again over the next few years.
