Who knows about the Milky Way, about the Milky Way

Just look at the encyclopedia.

Focus: A disk-shaped star system of more than 200 billion stars, thousands of star clusters, and nebulae, with a diameter of about 100,000 light-years and a thickness of about 6,000 light-years at the center.

The Sun is located 10,000 light-years from the center of the Milky Way.

The age of the Milky Way is estimated to be about 13.6 billion years old.

The overall structure is as follows: the main part of the Milky Way material forms a thin disk called the silver disk, and the almost spherical part of the center of the silver disk is called the nuclear sphere. In the region of the nuclear sphere, stars are highly dense, and in its center there is a small dense region called the silver nucleus.

Outside the silver disk is a larger, nearly spherical system in which the density of matter is much lower than in the silver disk, called the silver halo. There is also a silver crown on the outside of the silver halo, and its material distribution is also roughly spherical.

The Milky Way rotates at a speed of 250 kilometers per second.

The Sun is in the Milky Way rotation period of 220e6 years.

The speed of movement relative to the 3k background is 600 km/h in seconds.

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 heart and four 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.

In general, the Milky Way and the solar system are very similar in their patterns and morphology. It's just that there are a lot of other substances in the Milky Way, such as black holes, dark matter, and so on.

The Milky Way has big black holes lol.

In fact, this kind of thing comes out when you search for "galaxy".

The Milky Way refers to a milky white bright belt across the starry sky, which was also known as Tianhe, Yinhan, Xinghe, Xinghan, and Yunhan in ancient China. 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 galactic belt, which is up to 30° at its widest point and only 4°-5° at its narrowest point, with an average of about 20°, which is only a part of the Milky Way.

The Milky Way occupies a very important place in Chinese culture, with the famous Chinese myth and legend of the Magpie Bridge meeting. The Milky Way is only visible on a clear night and is caused by the light of countless faint stars. The Milky Way is not a Milky Way, but a part of the Milky Way.

Milky Way: Milky Way, Tianhe, Xinghe, Tianhan, Yinhan, etc., is a barred spiral galaxy containing the solar system, with a diameter of 100,000 to 180,000 light years. There are about 100 billion to 400 billion stars and possibly 100 billion planets.

The Solar System is about 26,000 light-years from the center of the Milky Way, on the inner edge of a spiral arm with a dense cloud of gas and dust known as the Orion Arm. At the position of the Sun, the orbital period is about 240 million years. From the Earth, the Milky Way is in the shape of a band around the celestial sphere because it is from the inside of the disk-like structure outward**.

In fact, you can see the Milky Way all year round, but at the turn of summer and autumn, you can see the brightest and most spectacular part of the Milky Way. The main constellations through which the Milky Way passes are Cygnus, Aquila, Fox, Sagittarius, Ophiuchus, Shield, Sagittarius, Scorpio, Temple of Heaven, Ruler, Jackal, South Triangle, Compass, Fly, Southern Cross, Sail, Puttus, Monoli, Orion, Taurus, Gemini, Auriga, Perseus, Cassiopeia and Scorpio.

English: the), is the barred spiral galaxy in which it is located, including 1000 400 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. The total mass of the Milky Way is about a trillion times that of the Sun, and the nearest extragalactic galaxy is the Dwarf Canis Major galaxy 10,000 light-years away.

The Milky Way is the star system in which the solar system is located, including 1500 400 billion stars and a large number of star clusters, nebulae, as well as various types of interstellar gas and interstellar dust, black holes, and its total visible mass is 1 5 trillion times. The projection of the Milky Way in the sky is like a glittering river flowing in the sky, so it was called the Milky Way or Tianhe in ancient times, and the Milky Way can be seen all year round, but the brightest and most spectacular part of the Milky Way is seen at the turn of summer and autumn.

Principles of the formation of the Milky Way.

The two emitters of a black hole (supernucleus) are constantly generating various photons, and because these photons are located in the resting repulsion region of the black hole (i.e., the neutral field, the field structure of the black hole is similar to the field of the nucleus), they are repulsive by the strong black hole field and accelerate outward. Just like the principle of optical fusion in the Earth's self-circulation system, the extremely high-density group of photons that accelerates outward continues to condense into mass polar single particles such as electrons (including electrons) and protons as the black hole weakens during the movement. These massive particles, under the gravitational pull of the gravitational field of the finger block black hole, deviate from the original direction of motion, and under the mutual induction of their polar fields, two powerful particle streams are formed, which are called bipolar jets in astronomy.

There are stars and planets in the Milky Way. According to the relevant public information of the debate, the Milky Way Rock System is a huge system, containing a variety of stars and planets, including the earth, and a variety of meteorites.
