What are the properties of galaxy clusters, and what are galaxies experiencing in their extreme regi

The characteristic of galaxy clusters is that they disperse very quickly, reaching thousands of kilometers per second. The interior of a galaxy cluster is like a closed system in which celestial bodies are constantly developing.

Smaller clusters of galaxies will disperse more slowly, while larger clusters will diffuse 10 times faster than smaller clusters. In extreme regions, as galaxies pass through it, the intergalactic plasma is rapidly removed and eventually faces death.

The biggest characteristic of galaxy clusters is that they develop slowly, and their development time can be traced back to the beginning of the universe, and the stars in these galaxies continue to develop, and the galaxies in extreme regions will disappear.

Galaxy clusters are very large collection of galaxies, and galaxies in extreme regions are constantly being killed, and the study of galaxy clusters is still the focus of human scientists' research.

Small clusters of galaxies are active at a speed of about 400 kilometers per second, while large clusters can reach a speed of up to 2,000 kilometers per second, the development of star clusters is very slow, in extreme regions, many stars have closed their birth channels, and the galaxy where the star is located will collapse if there is not enough fuel.

Theoretically, disk-shaped galaxies were formed by clouds of hydrogen, which gravitationally attracted gas particles together. As the hydrogen atoms get closer and closer, the cloud begins to rotate and its overall mass increases, which causes its gravitational pull to rise again. Eventually, gravity causes the cloud to collapse and shrink into a rotating disk.

Most of the clouds are at the edges and are star-formed**. Astronomer Edwin Hubble confirmed the existence of galaxies a century ago when he called them disc galaxies late type galaxies because he suspected that their shape meant they formed later in the history of the universe.

One is a disk-shaped galaxy and the other is an elliptical galaxy, just as people have different looks.

This is like everyone is unique, different changes, different growth habits, will also cause a certain gap.

This group of galaxies refers to the group of galaxies formed by the Milky Way's opposition and some of the surrounding galaxies. （）

The number of members of a galaxy cluster is smaller than the number of members of a galaxy group. (Bi Short).

Correct Answer: a

The local group of galaxies refers to the group of galaxies formed by the Milky Way and some of the surrounding galaxies. That's right.

The local group of galaxies refers to a group of galaxies that form a small group of galaxies including the Milky Way and the adjacent Andromeda Galaxy and the Magellanic Nebula. All galaxies in this group of galaxies cover an area about 10 million light-years in diameter. This group of galaxies belongs to the much larger Virgo supercluster.

The Local Group of Galacies is a typical open cluster of galaxies.

There is no clear tendency to concentrate towards the center. There are about 50 member galaxies. The Milky Way and the Andromeda Galaxy are the two largest and most defeated galaxies in the Local Group, and they are roughly at the center of the Local Group.

With the exception of the Milky Way and the Andromeda Galaxy, the vast majority of member galaxies are dwarf galaxies. The radius of this group of galaxies is about 1 million parsecs, and the mass is about the mass of the Sun.

The vast majority of them are concentrated in the Milky Way and the Andromeda Galaxy. There are not many gases in the group, which accounts for about 2% of the total mass. There are two subgroups of this group of galaxies:

The Milky Way subgroup consisting of the Milky Way and the Large Magellanic Cloud, and the Andromeda subgroup with the Andromeda Galaxy as its center, including M 32, NGC 205, NGC147, NGC185, Andromeda Dwarf and Triangular Galaxy (M33).

The Local Group is a member of the Local Supercluster. The so-called local galaxy group refers to the general term for the galaxies in space with a radius of about one million parsecs (more than 3 million light years) as the center of the Milky Way where the Earth is located, and some people define the center of this galaxy group as the common center of gravity of the Milky Way and the Andromeda Galaxy (M31).

There are about 50 known member galaxies and possible member galaxies in this group. All galaxies in the Local Group cover an area about 10 million light-years in diameter (see 1e23 m dry for a detailed idea of this distance). This group of galaxies belongs to the much larger Virgo supercluster.

A total of 24 superclusters have been discovered so far, and they are:

1. Neighboring superclusters:

1. Local supercluster: A supercluster of galaxies containing the local group of galaxies (including the Milky Way). The Virgo Cluster is located in the center, so it is sometimes called the Virgo Supercluster;

2. The Long Snake Centaur Supercluster: The circle is composed of two petals, and the whole is usually regarded as a supercluster, and sometimes individual parts of the whole are called the Long Snake Supercluster and the Centaur Supercluster.

3. Perseus Pisces Supercluster;

4. Peacock Seal Jane Blind Earth An Supercluster ;

5. The Comae Supercluster: forms a dwarf, the center of the fibers of the Great Wall galaxy;

6. Phoenix Supercluster;

7. Jadeite Supercluster 9;

8. Hercules Supercluster;

9. Leo Supercluster 93;

10. Sharpley Supercluster: the second supercluster discovered after the present supercluster;

2. The more distant superclusters :

1. Pisces whale supercluster;
