Human first black hole photo

Human first black hole photo (Picture 1)


Beijing time on April 10th news, astronomers captured the first black hole photos! The black hole image released this time reveals the black hole in the center of the supermassive galaxy M87 in the Virgo Cluster, which is 55 million light-years from the Earth and 6.5 billion times the mass of the Sun. Many of the features of this image are completely consistent with the predictions of Einstein's general theory of relativity, which further validates general relativity in the extreme environment of strong gravitation.

In Brussels, Belgium, Santiago, Chile, Shanghai and Taipei, Shanghai, Japan, and Washington, DC, the world's six global conferences were held in English, Spanish, Chinese, and Japanese, and the event vision telescope (EHT) project was announced. This major achievement. This is an extraordinary research achievement completed by a team of more than 200 researchers from around the world.

Lu Yujun, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences, said: "It is relatively clear that the black hole of the star-quality quality is the remains of the star collapse; while the massive black hole may be grown by the medium-quality black hole accretion material produced by other mechanisms. "All stars are nuclear fusion reactors, and the nuclear fusion process provides most of the energy of a star's life. However, in the end, the nuclear fuel is exhausted, and the energy generated by the center is no longer able to withstand the huge weight of the outer casing, and gravity begins to dominate.

According to the theory of relativity, nothing can travel faster than light. If light can't escape, other things are even less likely: everything will be pulled back by the gravitational field. In this way, there is a collection of events or space-time regions where light or anything can't escape from the region and reach distant observers. We call this region a black hole and call its boundary the event horizon.

Although scientists can't see the body of a black hole, they can trace back to the "vision" where photons disappear. This is the limit we can "see". There are indeed some luminescence phenomena around the black hole. For example, when the black hole eats the surrounding stars, it will tear the star's gas to the side to form a rotating accretion disk. Black holes sometimes "snap", and some of the accretion gas is ejected in the direction of rotation to form a jet. Accretion disks and jets produce bright light due to gas friction and radiation in other frequency bands.
