What exactly is the central highlight of the Milky Way

It is possible that some stars gathered together, and this one is worth exploring.

I think it's a shadow that causes the bright spots, so there's nothing about it.

It belongs to a special substance, like the black spots of the sungrouse.

I think the bright spot at the center of the Milky Way galaxy may be formed by the reflection of light from some asteroids.

<>In ancient times, due to the lack of knowledge of the ancients, people always regarded the earth as the center of the universe, and the sun in the sky, including the moon and morning star, revolved around the earth. It was not until later, when Copernicus proposed the heliocentric theory, that the "geocentric theory" was slowly refuted. But with the development of scientists, people gradually discovered that the "heliocentric theory" is also flawed, because if you put the sun in the whole galaxy as a comparison, the sun is just a small star in the galaxy, and the whole galaxy is 100 billion to 400 billion stars.

Obviously, the Sun is not the center of the Milky Way, so what exactly exists at the center of the Milky Way? It is thought that the reason why hundreds of billions of stars revolve around it is related to the bright spot at the center of the galaxy. As for the mysterious highlights, scholars believe that there are three possibilities.

The first possibility was proposed by Jansky, an engineer at Bell Labs in the United States. He was the first to observe the structure of the Milky Way using infrared and radio signals.

Jansky believes that the infrared radiation and radio signals at the silver center are very strong, so the highlight of the silver center may not be a simple stellar dense nucleus, but a group of very large dwarf stars. The second hypothesis was proposed by a British astronomer in 1971. He thinks there is a large, dense core or a super-black hole in the center of the silver.

Black holes are at least a million times more massive than the Sun. But there is a necessary premise for this sentence, that is, the silver heart must have a strong radio power.

This hypothesis was supplemented in the 80s of the 20th century, when an American astronomer discovered that the air flow rotated around the center of silver at a speed of 200 kilometers per second. The farther these gases are from the center of the silver, the slower they flow. Therefore, there is some evidence for the existence of black holes.

But this view was opposed by astronomers in the former Soviet Union. If there is a huge black hole at the center of the Milky Way, then the dazzling point of light emitted by the silver center should be the result of the black hole ejecting matter. In fact, this is not the case.

It is also believed that the center of silver is actually the birthplace of stars, which have a total mass of more than 100,000 times that of the Sun and a temperature of more than 300 K.

The reason why the center of the Milky Way is bright: because there are many stars in the center of the Milky Way. According to scientists' estimates, about 90% of the stars are concentrated in the center of the Milky Way, about 200,000 light-years away.

In the solar system, one sun is enough to illuminate the entire galaxy, and when millions, tens of millions, or even hundreds of millions of star systems are gathered at the center of the Milky Way, the brightness of the center of the Milky Way is very high.

There are about 42 million stars in light-years around the center of the Milky Way, which is 72 million times more dense than stars near the solar system. With so many stars clustered around the Milky Way, it naturally makes it appear very bright.

The origin of the nuclear sphere at the center of the Milky Way:

1. One theory is that at the same time as the formation of the Milky Way 13 billion years ago, the structure of the nuclear sphere was also created, so the existing nuclear sphere should all be old stars with similar motion.

2. Another theory is that the nuclear sphere did not appear at the same time as the Milky Way, but only after the latter produced the first generation of stars in the process of slow evolution. According to the second theory, it is speculated that there may also be relatively young stars in the nucleus now, and there is a difference in the motion of the old stars.

Black hole. When a black hole devours material near it, it emits energy in the form of light, and the presence of the black hole is detected by detecting this light energy. The centers of nascent galaxies and quasars are usually extremely bright, and it is the black hole at the center that is devouring the surrounding matter, emitting a lot of energy.

By chance, an asteroid approaches the black hole, which pulls it over and tears it to pieces, so that these bright flares can be seen.

As the black hole gets older, the engulfing rate slows down, "eating" less and becoming darker. "We're looking at what happens to black holes when they get old. Joy Nelson, a postdoctoral fellow at the MIT Covli Institute for Astrophysics and Space Research, said, "Black holes are not like young quasars, but they are still active.

The number of stars in the Milky Way galaxy is estimated at 200 billion. So many stars, without exception, orbit around the center of the Milky Way. So, what is it that is the brightest part of the galactic core that makes 200 billion stars revolve around it?

In the summer night sky of the Northern Hemisphere, there is a band of white light that extends from the southern sky to the northern sky. It is light from the disk of the Milky Way. Our solar system is not at the center of the Milky Way, it is actually 26,000 light-years away.

From Earth, the center of the Milky Way is located in the direction of the constellation Sagittarius.

<>Although many galaxies show that the center of the Milky Way is very bright, we do not see this phenomenon in reality. This is because there is a large amount of dust scattered in the interstellar space between the center of the Milky Way and the solar system, blocking most of the visible light from the center of the Milky Way. The center of the Milky Way is actually very bright because the stars there are so dense.

As many as 10 billion stars, or 5% of the total number of galaxies, inhabit spheres with a diameter of 13,000 light-years. The closer you get to the center of the Milky Way, the denser the stars become.

About 300,000 stars are concentrated in space one cubic light-year around the center of the Milky Way. In the space of 50 cubic light-years around the center of the Milky Way, there are tens of millions of stars. The distance between the stars around the Sun is generally 4 light-years, and the nearest star, the constellation Centauri, for example, is light-years away.

If the center of the Milky Way had not been blocked by interstellar dust, we would have been able to see light from billions of stars at the center of the Milky Way from Earth, even if it was more than 20,000 light-years away. Their total brightness can easily exceed the brightness of a full moon, and the night sky will look completely different.

If our solar system were at the center of the Milky Way, the sky would be filled with stars, 200 times brighter than the Full Moon, and a million stars as bright as Sirius could be seen. In such a place, there will be no night, and it will be difficult to receive light from the universe beyond the center of the Milky Way. The Sun and other stars orbit around the center of the Milky Way in their own orbits.

The closer you are to the center of the Milky Way, the faster the star will spin and vice versa. The Sun moves around the center of the Milky Way at a speed of about 230 kilometers per second, once every 100 million years. Since the beginning of our solar system, the Sun has carried us around the center of the Milky Way 20 times, or 20 galactic years.

The brightest places are the stars, the sun, the moon, during the day, we rely on the light, heat and light emitted by the sun to meet our day's travel and life, and at night, the moon and stars will give us a lot of light, accompany us to sleep.

The largest place in the middle of the Milky Way is the Silver Core, which is an approximately spherical region with a radius of up to 10,000 light-years and a large number of stars.

The brightest region is called the silver core, which is an approximately spherical region with a radius of about 10,000 light-years.

Mankind's understanding of the universe is a gradual process. Gradually, they recognized the Milky Way and discovered a very bright region in its center. The center of the Milky Way is bright because the stars there are dense, and the huge number of stars will surely shine brightly together.

Thanks to advanced observation techniques, we have been able to clearly see what the stars of the Milky Way look like. Its shape looks like an oval disc, and its central area is very bright. At first, scientists thought it was strange.

They tried to observe the Milky Way in different bands and found that the different bands did not affect its brightness, and the central region was still bright.

1. Scientists are exploring the cause of luminescence in the central region of the Milky WayIt is found that the distribution of stars in the Milky Way region is uneven, and their density has a lot to do with the distance from the center of the star. The density of stars near the center of the Milky Way is relatively high. The brightness of the center of the Milky Way can be observed because of the dense distribution of stars in that region.

Human beings used to believe that the earth was the center of the universe, and the sun, moon, and stars all revolved around the earth. Later, mankind gradually discovered that the Earth is just a planet that revolves around the sun.

Second, scientists further found that the center of the Milky Way is too dense with starsAs a result, it is very difficult for life to exist there. Because of all kinds of harmful radiation, it is difficult to sustain life. Scientists have also discovered that there is a special celestial body at the center of the Milky Way, and its name is Sagittarius A.

Later, mankind discovered that the sun is just an ordinary star in the universe, and together with hundreds of billions of stars, it forms a huge galaxy called the Milky Way.

3. Sagittarius A has a strong gravitational pull, but it is relatively small. Scientists compared it with other celestial bodies and concluded that it was most likely a black hole. Subsequent scientists continued to observe it and found that some of its features were indeed consistent with black holes.

The black hole devours the surrounding stars, which radiate outward after being swallowed. The reason why the center of the Milky Way can be seen sparkling is most likely because these stars are being swallowed by black holes. This speculation has been recognized by many scientists and is a relatively reliable conclusion.

Because there are many stars in the center of the Milky Way, the density of stars is very large, so we will be very bright when we see it from a distance.

There are many stars in the center of the Milky Way, and they are denser, which is why they look so bright.

I think there may be stars, because stars emit light, and the luminous area of stars is quite large.

The brightest part of the center of the Milky Way is not a star, because the disk of the Milky Way is at least 100,000 light-years in diameter, and the brightest part is obviously light-year, much larger than a star with a diameter of at most a few billion kilometers (about one or two light-hours). In fact, there are very dense stars in the galactic center, and they appear very bright when they come together.

In the Milky Way, the closer you are to the galactic center, the higher the density of stars; And the closer to the edge of the silver disk, the lower the stellar density. The solar system is about 10,000 light-years away from the galactic center, and there are only about 10,000 stars on average in each cubic light-year of space near the Sun (equivalent to a sidereal cubic parsec). In globular clusters with a higher stellar density, their star density is about 2 cubic light-years, which is equivalent to 500 times the vicinity of the Sun.

And within the light-year space around the galactic center, there are up to 42 million stars, which means that the star density there is as high as 10,000 cubic light-years, which is equivalent to 72 million times that near the Sun.

Due to the large number of stars gathered near the galactic center, it appears very bright. There, on average, there is a star every 1,000 astronomical units (equivalent to 6 light days). If the Earth were near the galactic center, we would see a million stars brighter than Sirius, and the entire night sky would be about 200 times brighter than it would be at the time of the Full Moon.

However, due to the large amount of interstellar dust, we cannot see the bright silver heart on Earth. But infrared rays with longer wavelengths are more likely to pass through interstellar dust, so in the ** of the infrared band, the silver core appears very bright.

In addition, there is a supermassive black hole with a mass equivalent to 4.3 million suns, Sagittarius A*, in the deepest part of the galactic center, and some stars orbit it because of the gravitational constraints of this black hole.

At the center of the Milky Way is the Silver Heart. The galactic center is the intersection of the Milky Way's axis of rotation and the galactic plane, the center of the galactic core, and the center of the Milky Way. The Silver Heart is located in the direction of Sagittarius.

This region is mainly made up of a large number of stars. The mass of the silver core is about 4 million times the mass of the sun. Some people think that the galactic core region is a massive dense nucleus, perhaps a massive black hole.

By the way, a word about the silver core. The silver core is a slightly convex part of the Milky Way**. It is a very bright spherical body, about 20,000 light-years in diameter and 10,000 light-years thick.

This region is made up of a high density of stars and interstellar matter, the main of which are old red stars that are about 10 billion years old. The activity of the silver core is very intense.

The center of the Milky Way is the galactic center, and the center of the Milky Way is the black hole, and there are at least two or more, a large and a small one, and there are many supergiant stars in the vicinity of the black hole, which are the brightest stars that make us see not a black hole from the naked eye, but a cluster of light. German astronomers confirmed the number of black holes in 2008, so that the stars next to the black holes can continue to orbit, albeit chaotically (still caused by black holes).

The radio telescope found that there is a strong radio source at the center of the Milky Way, which is named Sagittarius A. The center of this radio source is particularly small, and the maximum is no larger than Jupiter's orbit around the Sun. It has been suggested that if the radius of the central nucleus of the Milky Way is no larger than a parsec, i.e., no more than light-years, it means that it is likely to be the center of a massive compact object, most likely a black hole.

If the radius of the central nucleus is a parsec, that is, about 2 light-years, then if it is not a black hole, it would be a very massive mass of matter, containing the mass of 2 million suns. Based on the observations of astronomical satellites in 1987 and 1988, Japanese scientists believe that there was a massive celestial body or a large number of supernovae in the galactic center.
