Which constellations of the stars we see with the naked eye on the earth do not belong to the Milky Way?

Which constellations do not belong to the Milky Way?

The mystery of the universe is profound. According to the research of astronomers, all the stars we see on the earth are basically within the Milky Way, and they are all very big. These stars in the sky are all stars in the Milky Way that can emit light and heat. Whether these stars can be seen by humans depends on two factors, one is the distance between the stars and the earth, and the other is the brightness of these stars themselves. The brightness is not enough or the distance is too far to enter our human sight. The beautiful starry sky has become a beautiful landscape for us to watch nature at night, and it is also the best memory in our life.

The diameter of the Milky Way is about 654.38+ million light years. At present, the rocket launching speed is at least 6.5438+0.5 million years. If we want to observe celestial bodies outside the Milky Way, we need the help of high-precision astronomical telescopes. The stars we see in the sky now are roughly divided into four galaxies, the first is Andromeda, the second is Large Magellanic Cloud, the third is Small Magellanic Cloud, and the fourth is Triangle Galaxy. We divide these galaxies into many constellations, such as Orion, Andromeda, Libra and so on. That is, most of them are galactic objects in our visible sight.

In theory, the light emitted by stars can move infinitely in the universe and then enter human eyes. However, there are many celestial bodies in the universe that block the propagation of these light Xi. The nearest star is the sun. The reason why the earth is divided into day and night is because sunlight cannot be scattered in a vacuum universe.

If you want to feel the charm of the universe, you still need the help of astronomical telescopes. At present, the most accurate astronomical telescope can't see celestial bodies outside the Milky Way. This is limited by the current technical level of human beings, but I believe that in the near future. We humans can observe the universe outside the Milky Way, and even fly outside the Milky Way to explore the mysteries in the depths of the universe.

Weak weak q, Andromeda galaxy does not belong to the Milky Way?

No, Andromeda, a galaxy as big as a palace, does not belong to the Milky Way, but is another galaxy outside the Milky Way. This star system is called extragalactic galaxy. It means in a galaxy other than the Milky Way. Andromeda galaxy is a spiral galaxy with a huge disk structure, which is located in the slag rock of Andromeda. It is numbered M3 1 in messier catalog and NGC224 in the list of new stars in nebula clusters. The naked eye looks like a faint spindle-shaped oval spot, which is one of the most distant celestial bodies visible to the naked eye. Andromeda galaxy is larger than the Milky Way, with a diameter of 220,000 light years, at least 1.6 times that of the Milky Way. It is 2.54 million light-years away from the Earth and is the largest galaxy closest to the Milky Way. (Think about it, the diameter of the Milky Way is only 10, and it is 2 million du30,000 light years away from the Andromeda galaxy. How does Andromeda belong to the Milky Way? Andromeda and the Milky Way are both in the local galaxy group, which is the largest galaxy in the local galaxy group and constitutes the main galaxy of the local galaxy group together with the Milky Way. It is moving towards the Milky Way at a speed of 300 kilometers per second, and may hit the Milky Way in 4-5 billion years, eventually synthesizing an elliptical galaxy.

Where are the twelve constellations of the Milky Way?

Looking up, there are nearly 6000 naked-eye stars y ǒ u. We divide these stars into regions according to their distribution, that is, constellations, and connect the bright stars in the constellations with lines to form various figures, and we have the constellation of 12.

Constellation plays an important role in astronomy and is also the basis of western divination. Like our 12 zodiac, it is a part of eastern and western folk culture.

The twelve constellations are in the Milky Way, and the Milky Way is in a certain position in the universe. The specific location remains to be explored by our descendants.

Aries is one of the zodiac signs 12, and it is a fire sign. "In western astrology, the zodiac 12 is synonymous with the orientation of the universe. When a person is born, the position of the stars falls into the zodiac, which shows a person's innate character and talent. Zodiac 12 symbolizes the psychological level and reflects a person's behavior. "
