Galaxy problems, are the Milky Way and the Milky Way the same thing?

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.

The black hole does not travel through time and space but distorts time and space, the huge mass of the black hole makes the surrounding space seriously distort and produce great gravitational force, if a person enters the horizon of the black hole, he will immediately be stretched spaghetti, do you say can he live?

Wormholes are used for space-time jumps. A wormhole is an extremely distorted region of space-time in the universe, which can connect two regions that are very far apart through a single channel. For example, if you have two dots on a piece of paper, you want to connect them and have the shortest route, what should you do?

According to normal thinking, we must use line segments to connect them, but this is the shortest distance on the plane, and the problem is not limited to the plane, so we can change our thinking, put the paper in a nest, let the two points coincide, this is the real shortest distance in space. Wormholes are like this, but they are only theoretical, not observed. If a wormhole exists, it can make a space-time transition.

The Milky Way is a galaxy, there are no galaxies in it, the solar system is a planetary system, and galaxies refer to star systems. If you ask about extragalactic galaxies, there are more than 100 billion of them, such as the Great Magellanic Galaxy, the Andromeda Galaxy, etc. As for the celestial bodies, there are more than 200 billion stars in the Milky Way, plus the stars of other galaxies and all other celestial bodies, what is the total number, and I feel a chill on the back of my neck.

Addendum: The word galaxy is short for galaxy for no reason. There are about 18 billion planetary systems in the Milky Way.

As long as you travel through space, you travel through time. Space and time are interrelated and do not exist independently. Space changes with the passage of time, and time changes with the transfer of space. Each space has a corresponding time.

At the center of the Milky Way is a black hole with a mass of 3 million suns.

There are other stars besides the sun.

Before entering the black hole, the human being will be torn in half due to the gravitational attraction of the head and feet.

Supplement. The Milky Way is the star system in which the solar system is located, including 120 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. Its total mass is 140 billion times that of the Sun.

Most of the stars in the Milky Way are concentrated in an oblate sphere of space, which is shaped like a discus. The protruding part of the oblate sphere in the middle is called the "nuclear sphere", with a radius of about 7,000 light-years. The middle part of the nuclear ball is called the "silver core", and the surrounding area is called the "silver plate".

Outside the silver disk there is a larger sphere, where there are few stars and less dense, called the "galactic halo", with a diameter of 70,000 light years. The Milky Way is a spiral galaxy with a spiral structure. The speed and period of rotation of each part of the silver vary depending on the distance from the silver core.

The Sun is about 10,000 light-years away from the galactic center, orbiting the galactic core at a speed of 220,250 km/s for a period of about 100 million years.

The Milky Way has 4 spiral arms, namely the Centaur Arm, the Orion Arm, the Perseus Arm, and the Swan Arm. The sun is located on the inside of the Orion arm. The spiral arms are mainly made of interstellar matter.

The Milky Way galaxy also has a rotation. The solar system revolves around the center of the Milky Way at a speed of 250 kilometers per second for about 100 million years. The Milky Way has two companion galaxies:

The Great Magellanic Galaxy and the Small Magellanic System. The opposite of the Milky Way is called an extragalactic galaxy.

It is generally believed that most of the stars in the Milky Way are binary or clustered stars. In 2006, a new discovery suggested that 2 and 3 of the main sequence stars of the Milky Way were all single stars.

Latest News (2008

According to the National Geographic magazine, a few days ago, astronomers depicted the most realistic map of the Milky Way, the latest map shows that the Milky Way spiral arm is very different from the previous observations, the original four main spiral arms of the Milky Way, now only two main spiral arms, the other two arms are in an unformed state.

In a barred spiral galaxy like the Milky Way, the main spiral arm contains a high density of stars, capable of giving birth to a large number of new stars, clearly connected to the long stellar belt at the center of the galaxy. In contrast, the high gas density of the unformed spiral arm is not strong enough to form stars.

There's a black hole, and the Milky Way is like a big family, and the solar system is just one part of that family.

Black holes travel through time and space, and they are called "wormholes," and so far there are no real cases, but as soon as you enter a black hole, it's no exaggeration to say that in less than 1 second, you'll be pulled into spaghetti.

But wormholes are still possible in the future.

Wormholes are like shortcuts to space travel, and it's theoretically possible, but only the future can give us the answer.

So far, I have not been able to determine whether there is a black hole, and I personally do not believe that time can be reclocked, and the innocence of human beings is meaningless.

It's not the same. The Milky Way usually refers to images that we can see with the naked eye or various telescopes in the night sky. In reality, that's just a small part of the Milky Way.

Our Earth is actually part of the Milky Way. So, the concept of the Milky Way is much bigger.

The Milky Way Galaxy (foreign name: milky way galaxy, alias: Yinhan, Tianhe) is a barred spiral star system in which the solar system is located.

The galaxy includes 1500 400 billion stars and a large number of star clusters, nebulae, as well as various types of interstellar gas, interstellar dust and black holes. Its total visible mass is 210 billion times the mass of the Sun and its diameter ranges from 100,000 to 180,000 light years. The Milky Way is an oblate sphere with a huge disk structure, consisting of a bright and dense core, two main spiral arms, and two unformed spiral arms, so that when viewed from Earth, the Milky Way appears as a silvery-white ring around the sky.

Milky Way: the projection of the main body of the Milky Way on the celestial sphere as seen by an observer on Earth; In the clear night sky, it appears as a bright milky white band with irregular borders. In ancient China, the Milky Way was also known as the Heavenly River, the Silver Han River, and the Galaxy River.

It is a faintly glowing band across the starry sky, and the Milky Way intersects the celestial equator in the constellation Aquila and in the northern half of the celestial sphere. The Milky Way outlines a band of different widths on the celestial sphere, called the galactic band. It reaches 30° at its widest point and only 4° 5° at its narrowest point, averaging about 20°.

The milky way or galaxy is the star system in which the solar system is located, including 120 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. It has a diameter of about 100,000 light-years, a center thickness of about 12,000 light-years, and a total mass of 140 billion times the mass of the Sun. The Milky Way is a spiral galaxy with a spiral structure, i.e., with a galactic core and two spiral arms, which are 4,500 light-years apart.

The Sun is located on the Orion Arm, an arm of the Milky Way, at a distance of about 26,000 light-years from the center of the Milky Way.

The Milky Way is not a river in the sky, but a disk-like star system composed of more than 100 billion stars, in which our solar system itself is located. When we look around from the solar system, the disk-like part of this star system appears as a band-shaped celestial region, and the stars in this region are most densely projected. And because of the distance, the naked eye could not distinguish the dense star, so it was seen as a shining band of light, which is what we see as the Milky Way.

This massive star system also gets its name from the Milky Way and is called the Milky Way. So, the Milky Way and the Milky Way are two different concepts.

No. The Milky Way refers to a milky white bright belt across the starry sky, which is also known as Tianhe, Yinhan, Xinghe, Xinghan, and Yunhan in ancient China and the Milk Road in ancient Greece in Europe.

It turned out to be a vast lenticular star system composed of more than 100 billion stars, and our solar system is in this system. From the solar system, we see that the edge of the disk-shaped part is in a band-shaped celestial region. This region of the sky is most densely projected by stars, and this is what we see as the Milky Way.

This vast star system is also named after the Milky Way, called the Milky Way.

Milky Way (1

2) The Earth we are in is a planet in the solar system, which is located in a very large galaxy, the Milky Way. The Milky Way is 15 billion years old, with at least 200 billion stars and thousands of star clusters and nebulae. The protruding part is called the nuclear ball, and the disc part resembles four swirl arms, called the galactic disk.

The nuclear sphere is about 3,000 light-years in diameter, elliptical in shape, and is made up of about 40 billion elderly planets that are more than 10 billion years old. The Milky Way Disk is about 100,000 light-years in diameter, composed of planets less than 10 billion years old and with a high content of heavy metals, and the Solar System is also located on this Milky Way disk, about one-third of the way from the outer edge of the Milky Way, and the Sun is about 26,000 light-years from the center of the Milky Way. 3:

1. The Milky Way is also known as Tianhe, Yinhan, Xinghe, Xinghan, and Yunhan in ancient China, which is a milky white bright belt across the starry sky. The Milky Way intersects the celestial equator in the constellation Aquila and in the northern semicelestial sphere. The Milky Way outlines a wide and narrow belt on the celestial sphere, called the silver belt, which is 30° at its widest point, only 4° 5° at its narrowest point, and about 20° on average, which is only a part of the galaxy.

2. The Milky Way occupies a very important position in Chinese culture, and there are famous Han myths and legends that meet at the Magpie Bridge.

3. The Milky Way is only visible on a clear night and is caused by the light of countless faint stars (stars). The Milky Way is not a Milky Way, but a part of the Milky Way. The Milky Way contains hundreds of billions of stars, with a total mass of about 600 billion to 3,000 billion times the mass of the Sun, and a diameter of about 100,000 light-years.

4. Milky Way, also known as "Tianhe" and "Tianhan" in China. It looks like a white strip of light that cuts across the sky from northeast to southwest. There are many small spots of light in the Milky Way, as if sprinkled with white powder, and they are reflected in one piece.

In fact, a single white powder is a huge star, and the Milky Way is made up of many stars. Stars like the Sun have more than 200 billion in the Milky Way, and many stars have moons. Looking down at the Milky Way from space, the Milky Way looks like a vortex.

5. In the clear night sky, when you look up at the sky, you can not only see countless sparkling stars, but also see a faint ribbon of light like a scarf across the entire sky, like a big river in the sky, in the north-south direction in summer, and close to the east-west direction in winter, that is the Milky Way. In the past, because science was not yet developed, guessing that God did not know what it was, so he gave it a name called Tianhe, so there are many beautiful myths and stories such as the Cowherd and the Weaver Girl meeting at the Queqiao every Qixi Festival.

In fact, the Milky Way is part of the Milky Way, which is the galaxy to which the solar system belongs. Because of the bright band projected on the celestial sphere by its main part, it is called the Milky Way by our country. It's the star-covered round surface that we see when we look at the Milky Way from the inside.

Because the light emitted by the stars is far away from us, so large in number and mixed with interstellar dust gas, it looks like a smoky band of light, which is very beautiful.

The brightness of each part of the Milky Way is different. The Centauri near the Silver Heart is a bit brighter than the rest of the city.

The Milky Way (formerly known as the Milky Way, Tianhe Mochong, Xinghe, Tianhan, Yinhan, etc.), is the galaxy where the solar system is located, (also known as Tianhe or Tianhan), which belongs to the barred spiral galaxy, including 1000 to 400 billion stars and a large number of star clusters, nebulae, as well as various types of interstellar gas and interstellar dust. With a diameter of about 100,000 light-years and a thickness of about 10,000 light-years at its center, it can be seen that the total mass of matter is about 1,400 trillion times the mass of the sun.

The Milky Way has a massive disk structure with a galactic core and four spiral arms (the latest research on the Milky Way has only 2 spiral arms, of which the Orion arm, where the Sun is located, is only a small fork of the main spiral arm), and the spiral arms are 4,500 light-years apart. The Sun is located on the Orion Arm, a branch arm of the Milky Way, and the distance from Wang Zheng's center in the Milky Way is about 10,000 light-years. The Earth we live on is a planet in the solar system.

In January 2003, British scientists discovered that the outer part of the Milky Way galaxy may be embedded with a huge ring of billions of stars. In March 2015, scientists discovered that the Milky Way is 50% larger than previously thought.
