What kind of galaxy is the Andromeda Galaxy, which we can see with the naked eye?

In the clear autumn night sky of the countryside, the Andromeda galaxy is located 2.54 million light-years from Earth in the direction of the constellation Pegasus, which resembles an elliptical core, with a slightly larger chroma, and a faint galaxy diffuses in its vicinity. There are probably more than four children full moon moon angle.

In the suburbs or villages, the fairy is very easy to find, and when you look up, you can see that its diameter exceeds the moon and the chroma exceeds that of the Milky Way, so it is relatively easy to find. However, like looking at the Milky Way gradually, it is very easy to misinterpret it as a cloud at night, so it is necessary to be a little careful, unlike the smoke cloud, it is not easy to change in a short period of time, and its appearance is even less likely to change, so it can be clear if you look at it carefully. The diameter of the sun is 1.4 million kilometers, the earth is hundreds of millions of kilometers away from the sun, we see the sun on the earth is much smaller than the menstrual period, because the distance is relatively far, so it looks smaller, although the diameter of the Andromeda galaxy is 200,000 light years, but the specific distance from the Milky Way is 2.2 million light years, a light year is about a trillion kilometers, the distance is very large.

Therefore, there is no doubt about the appearance and stars, and it is not easy to observe with the naked eye.

If you want to see it in detail, you must have a telescope, and it is not important to increase the magnification, the key is the specification, and the larger the specification, the better. Be sure to have a tripod so you can see it smoothly. Because of the rotation of the earth, it is moving in the telescope, and the larger the magnification, the faster the rate of movement, but this does not mean that it is actually moving, but because of the rotation of the earth.

Gradually looking at the starry sky with a telescope, it is proposed that two people are above, not by water, and not in a fortress or balcony. Since there is a slight feeling of discomfort in looking at it gradually, especially when looking at the moon, in order to be better not to worry, it is necessary to have someone to practice courage.

The planet is flat, so it depends on the direction of the house where the cake is facing. If it is at an angle to the Earth, it is basically a line. At such a distance, there should be very few planets visible to the naked eye, and the part of the planet with a relatively high density is concentrated in the middle of the pie, so that only the middle part of the planet is seen.

In other words, if you use a telescope, it is very likely that what you will see is not a point at all, maybe a larger pie or a line.

The Andromeda Galaxy is a very large galaxy, there are many planets in this galaxy, there are also many planets and stars, and scientists ** in 4 billion years, the Andromeda Galaxy will merge with the Milky Way.

It is an oval-shaped galaxy with a slightly brighter center that emits Android starlight to the surrounding area.

It's a spindle-shaped elliptical galaxy, and this galaxy has a very large number of stars, a very large galaxy.

In the clear autumn starry sky in the countryside, the Andromeda galaxy is 2.54 million light-years away from Earth in the direction of Pegasus, which is oval-shaped, with a slightly brighter center and a faint starlight diffusing around it. There are about four full moon perspectives.

In the suburbs or rural areas, the fairy is easy to find, and when you look up, it is more diameter than the moon and brighter than the Milky Way when viewed from the ground, so it is easy to find. However, as with the Milky Way, it can easily be misunderstood as a night cloud, so be patient, unlike the smoke cloud, its position will not change in a short period of time, and its shape will not change, so be patient and observe for a while to be sure. The diameter of the sun is 1.4 million kilometers, the earth is 100 million kilometers away from the sun, we see the sun on the earth is much smaller than the menstruation, because the distance is relatively far, so it looks smaller, although the diameter of the Andromeda galaxy is 200,000 light years, but the actual distance from the Milky Way is 2.2 million light years, a light year is about a trillion kilometers, the distance is quite large.

Therefore, it looks like a star, and it is difficult to observe with the naked eye.

If you want to see it in detail, you need a telescope, the magnification is not important, the important thing is the aperture, the larger the aperture, the better. It is necessary to have a tripod so that it can be seen steadily. Due to the rotation of the earth, it is moving in the telescope, and the higher the magnification, the faster the movement, but this does not mean that it is really moving, but the reason for the rotation of the earth.

To start looking at the starry sky with a telescope, it is recommended that there are more than two people, not by water, and not on high ground or balconies. Because there will be a sense of insignificance and oppression when you start to look at it, especially when you look at the moon, in order not to be afraid, it is necessary to have someone to be courageous.

One is that the galaxy is flattened, so it depends on the direction of the pie. If it is perpendicular to the view of the Earth, it is basically a line. The second point is that at such a distance, there should not be many stars visible to the naked eye, and the part with high star density is concentrated in the middle of the pie, so that only the middle part of the galaxy is actually seen.

In other words, if you use a telescope, you may not see a point at all, maybe a relatively large pie or line.

You can find the North Star first, and then to the east of the North Star, you can see the constellation Cassiopeia, and next to the constellation Cassiopeia is Andromeda.

It could be in a galaxy in the universe, or at the edge of a galaxy, because many galaxies are distributed in different locations.

It's 254 light-years away, about 220,000 light-years in diameter, and has 1 trillion stars, and this galaxy is huge.

Andromeda, one of the eighty-eight constellations, is the Andomeda of Greek mythology. Most people have little knowledge about galaxies. So what galaxies does Andromeda have?

Together andKnowledge of horoscopesCome and see. In the constellation Andromeda there is a withered main galaxy, the Andromeda Galaxy, which is one of the largest members of the group. It is located below the constellation Ursa Major, near the constellation Pegasus.

The head of the fairy is Bisu II, which is one of the horns of the Pegasus quadrilateral. The Andromeda Transgalactic Galaxy, like the Milky Way, is a celestial system; Satellite galaxies of the Great Andromeda Galaxy discovered before 1900, such as the elliptical galaxy M32, the elliptical galaxy M110, the dwarf ellipsoid galaxy NGC185, and the NGC147.

The Great Andromeda Nebula has a total magnitude of 4 magnitude and an average brightness of 6 per unit area, and a clear and moonless night is faintly visible to the naked eye, like a small white cloud. Its soft silvery-white oval shape can be seen through a small astronomical telescope. The Great Andromeda Nebula is a typical spiral galaxy, but because it is facing us sideways, it is not easy to see its spiral arms.

Some of its structures can be seen through larger telescopes, such as its core is particularly bright and gets brighter towards the center, as well as spiral arms, black dust lines, globular clusters, and stellar clouds. Two of its dwarf galactic companions can also be seen, a small, round, dense elliptical galaxy M32 to the south of the core of M31, and a slightly fainter but larger and longer elliptical galaxy M110 to the northwest of M31. There are also many fainter stars in the Milky Way that fill this celestial zone, adding to the fascinating color of the Great Andromeda Nebula.

The Andromeda Galaxy is the closest large galaxy to our Milky Way. The Milky Way is thought to resemble the Andromeda Galaxy in appearance, and together they dominate the local group of galaxies. The light that pervades the Andromeda Galaxy is the result of hundreds of billions of stellar members.

The bright stars surrounding the image of the Andromeda Galaxy are actually stars in our galaxy, much closer than the objects in the background. The Great Andromeda Galaxy is also known as M31 because it is the 31st diffuse object in the famous Messier Cluster Nebula Catalog. M31 is quite far away, and it would take 2 million years for the light emitted from it to reach Earth.

The stars in the nebula can be divided into about 20 colonies, which means they may come from smaller galaxies that are engulfed by the Andromeda Galaxy.

The Celestial Virgo Galaxy is a constellation located in the sky, and it is also a massive galaxy. The Andromeda Galaxy is very far away from Earth, at the edge of our galaxy, so we can only observe it through telescopes.

Morphology and characteristics of the Andromeda Galaxy.

The morphology of the Andromeda Galaxy is an oblong oval and very beautiful. It is much smaller than our Milky Way, but it contains a very large number of stars, estimated to be in the tens of billions. It also has huge areas of gas and dust that are ideal for the birth of stars.

A black hole in the Andromeda Galaxy.

The Andromeda Galaxy is home to many huge black holes that collapsed from stars and are hundreds of times more massive than the Sun. These black holes can affect the surrounding stars and gas, and can even turn them into optical interference, making it difficult for astronomers to accurately measure the position and distance of certain celestial objects.

Interstellar dust in the Andromeda Galaxy.

There is a lot of interstellar dust in the Andromeda galaxy, which obscures the light of some stars, causing them to look faint in visible light. This interstellar dust also plays an important role in star formation and the interaction of the gas around them.

Conclusion. Although the Andromeda Galaxy is very far away, it is of great value to astronomers because it has many unique features and phenomena that can help us better understand how the universe works.

Although they have understood that the Sun is an ordinary star located in the Milky Way, they do not know whether there is a celestial system composed of many stars like the Milky Way in the universeAs a result, the celestial system known today as the "Andromeda Planet" was thought to be the "Andromeda Nebula" until the 20th century, and this incorrect was not recognized by the British scientist Edwin until the beginning of the 20th century. Hardened. At that time, Hubble used the cycle-time light source calibration method to analyze the "star track" of Andromeda, and concluded that a "Cepheid variable star" was located in it.

And this star is obviously not in the scope of the Milky Way, so Hubble dared to clarify that the Andromeda "star track" is actually a large planet with many stars like the Milky Way, and a kind of large galaxy is also a common phenomenon in the universe. In the Milky Way, the Andromeda Galaxy is one of the closest extragalactic galaxies to the Milky Way, with a distance of about 2.54 million light-years. For people, it's crazy for you.

2.54 million light-years is equivalent to 240 billion billion kilometres, and the 192-kilometre Parkson Solar Probe would have to cover a distance of nearly 4 billion light-years.

Because the Andromeda galaxy itself is full of light, including a total of 1 trillion stars, its specific chromaticity is about 34 billion times that of sunlight and twice that of the Milky Way, which prompts us to see this extragalactic galaxy immediately with the human eye on the long Earth. And because the Andromeda Galaxy is so large that it can have an aperture of up to 220,000 light-years, it doesn't look like a shining point, and its apparent aperture can be up to 6 times that of the Full Moon. The distance of 2.54 million light years is too long, and the Andromeda Galaxy can only be seen with the human eye in the far suburbs, where there is very little air and environmental pollution.

In addition, people cannot see the cantilevered structure of the Andromeda Galaxy, only the shiny part of the core can be seen, showing a cloudy shape. Even in a 150mm telescope, the Andromeda galaxy appears to be just a yellowish mass of light. Biologists have observed that the Andromeda Galaxy is gradually approaching the Milky Way.

Therefore, in the future on the earth, it will become bigger and brighter. About 3 billion light-years to 4 billion years later, the Andromeda Galaxy will meet the Milky Way, and you will see a very magnificent starry sky on Earth - the Andromeda Galaxy.

In the universe, the Andromeda Galaxy is relatively far away from the Milky Way, about 2.54 million light-years away, and this distance is out of reach for us humans; We can't see the Andromeda Galaxy with the naked eye, because it's so far away from us, and it's very large, up to 220,000 light-years in diameter, so we can't see it.

The constellation Andromeda is about 2.54 million light-years away; We can't see the Andromeda Galaxy because it's still a bit far away.

The distance between the Andromeda Galaxy and Earth is 2.2 million light-years. What is not visible to the naked eye at all, can only be observed through some astronomical telescopes.

Andromeda is the daughter of Cassiopeia and Immortal Throne, and we may be able to find the existence of Andromeda when we look up and look at it on autumn nights, and the location of the Andromeda Nebula is north of the sixteen stars of Kuiju. So is Andromeda a galaxy in the banking system? Next, let's go with me to the Eighty-Eight Zodiac Signs to have a look!

Andromeda is one of the galaxies in the banking system, which is composed of the Milky Way and about 40 galaxies of various sizes, including the Andromeda Galaxy. Galaxy clusters are vast celestial systems formed by the gravitational aggregation of galaxies, gases, and large amounts of dark matter. Tens of thousands of galaxy clusters have been discovered, up to 7 billion light-years away.

The more famous ones are the Virgo Cluster, the Comae Cluster, the Hercules Cluster, etc. This superlocal cluster includes the Home Cluster, the Virgo Cluster, the Ursa Majora Cloud, and about 50 clusters of galaxies.

With a long diameter of about 98 million to 245 million light-years, it may be spinning and expanding, and the Milky Way orbits the center of the cluster for a period of 100 billion years. Of course, these are the opinions of some leading figures in the international astronomical community, and we will consider him to be the mainstream view. Because astronomy is so mysterious, it's all too common to have different opinions.
