The center of the Milky Way is very bright. Is there a super-large star there? But there may be more than one

The Milky Way galaxy we live in is a very beautiful galaxy, especially its center, which is very bright.

Why is the center of the Milky Way so bright? Is there a supermassive star there? There are indeed stars there, but there is definitely more than one. There is a galactic black hole at the very center of the Milky Way. Under the strong gravitational force of this black hole, a large number of stars revolve around it, and thus the central system of the Milky Way was born. We call it the "Galactic Core", which is the very bright area we are talking about. The diameter of the Milky Way is about 100,000 light years, while the diameter of the Silver Core is about 20,000 light years. A large number of stars gather in this area.

How many stars are there in the core of the Milky Way?

If the Milky Way is regarded as a city, then our solar system is the rural area of ​​this city, where stars are rare. There is only one star in the solar system, the sun, and outside the solar system, the nearest star to us is Proxima Centauri, which is about 4.2 light years away from us, and because it is a red dwarf with very low brightness, we cannot see it directly with the naked eye. As for other stars, they are even farther away from us. On average, in the area where we are, there are only 0.004 stars per cubic light year.

The star density in the core of the Milky Way is much higher than that in our area.

In the galactic core region, within 1 parsec from the center, that is, within 3.26 light years, there are as many as 40 million stars. On average, there are about 290,000 stars per cubic light year. Obviously, the star density in the galactic core is very different from that in the area where the sun is located, which is nearly 70 million times different. This is why the galactic core looks bright, while the area where we are is shrouded in darkness. It's like looking down at the earth in the night sky. We can easily tell where the city is and where the countryside is, because the lights on the earth will indicate everything.

Do you feel a little regretful after reading this?

If our Earth is not located in the countryside of the Milky Way, but in the center of the Milky Way, wouldn't our nights be as bright as day? In fact, there is no need to regret. The brightness of the core of the Milky Way only looks very beautiful, but it is actually a forbidden zone for life. Why? Because the density of matter there is too high. It is not easy for life to be born on a planet. It requires a long-term stable environment, especially the emergence of intelligent life, which takes billions of years of evolution. However, the center of the Milky Way obviously does not have such conditions.

At the center of the Milky Way, it is difficult to find a habitable area because the density of matter is too high.

Even if a star happens to be located in the habitable zone, it is difficult for it to have a long-term stable ecological environment, on the one hand because there will be more celestial impact events in the high-density material area, and on the other hand because of the continuous evolution of many stars. The ability of stars to emit light and heat comes from the nuclear fusion reaction inside. As the fuel of the star is exhausted, its life will enter the end, and then a series of celestial activities such as helium flash, expansion, and supernova explosion will occur. These celestial activities are very intense and will release huge amounts of energy, with a range of up to tens of light years.

If you live in the central region of the Milky Way, you will easily be affected by the evolution of the surrounding stars, which will lead to the complete destruction of the ecological environment. Therefore, this is definitely a forbidden zone for life.

Of course, life cannot appear in the center of the Milky Way, nor in areas where matter is too sparse, because many of the substances needed for life are produced during the evolution of stars. Areas where matter is too sparse do not have enough material types to create life, so only areas like the solar system are the breeding ground for life. So we are lucky to be villagers in the Milky Way.
