Nice galaxy names
Nice galaxy names. The mysteries of the universe are treasures that we need to explore throughout our lives. We know that there are many galaxies and asteroids in the universe. These beautiful scenery of the universe that we have given names have the same charm as their names. Take a look at the nice ones below. Galaxy name.
Nice galaxy names 1
1. The Large Magellanic Cloud (LMC; also known as the Large Magellanic Cloud, or the Barley Cloud) is one of the famous extragalactic galaxies in the Local Galaxy Group and a dwarf galaxy.
It is the most massive of the many satellite galaxies of the Milky Way. It is located at the junction of Doradus and Montenegro. It is about 160,000 light-years away. Its diameter is about 1/20 of the Milky Way. The number of stars is about 1/10 of the Milky Way (about 100 billion).
2. The Small Magellanic Cloud (abbreviation: SMC; also known as the Small Magellanic Cloud, abbreviation: Wheat Cloud) is located between the constellations Tucana and Hydra. It is a dwarf galaxy and irregular galaxy adjacent to the Milky Way.
The Small Magellanic Cloud is about 7,000 light-years in diameter, contains hundreds of millions of stars, and has a total mass of about 7 billion times that of the Sun. It is about 200,000 light-years away from the Milky Way and is one of the closest extragalactic galaxies.
3. Andromeda Galaxy (English: Andromeda Galaxy; M31; NGC 224; once known as the Andromeda Nebula), a spiral galaxy with a huge disk-shaped structure located in the direction of Andromeda, Messier catalog number M31, nebula star cluster The new general catalog number is NGC 224, with a diameter of 220,000 light-years and a distance of 2.54 million light-years from the Earth. It is the nearest large galaxy to the Milky Way.
4. The Fornax Dwarf Galaxy is a dwarf galaxy located in the direction of the Fornax constellation, hence its name. It is one of the satellite galaxies of the Milky Way and one of the many dwarf galaxies in the Local Group of galaxies. It is one of the first two dwarf elliptical companion galaxies discovered in the Milky Way.
5. The Cyprus Dwarf Galaxy is a dwarf elliptical galaxy in the constellation Cyprus. It is 4.3 million light-years away from the Earth and is a member of the Local Group of Galaxies. The Cyprus dwarf galaxy was discovered in 1999 by Alan Whiting, George Hsu and Mike Owen. Its location happens to be on the .0 velocity surface of the Local Group of galaxies.

1. Serpens "Ring" Galaxy
The Serpens "Ring" Galaxy (AM 0644-741) is about 600 million light-years away from the Earth. Its outer periphery is a ring composed of bright blue stars, while the central sphere is mainly composed of many possibly smaller stars. Old red giant star composition. In between is a rift of almost total darkness. How this peculiar state came to be is still unknown.
2. Hydra Overlapping Galaxy
The Hydra Overlap Galaxy (NGC 3314) is a deep-sky object in the constellation Hydra. It consists of two overlapping spiral galaxies, NGC 3314a (front) and NGC 3314b (back). It is about 117 million light-years and 140 million light-years away from Earth. Far.
3. Leo Spiral Galaxy
The Leo Spiral Galaxy (NGC 3370) is about 98 million light-years away from the Earth. In the center of the galaxy, there is a sharp dust belt and a not easily identifiable core. It is composed of blue young star groups and yellow old star groups. .
4. The Great Spiral Galaxy Eridanus
The Eridanus Great Spiral Galaxy (NGC 1232) is about 68 million light-years away from the Earth. There are a large number of blue stars distributed along the spiral arms in open star clusters within the spiral arms, and there are a large number of interstellar dust dark areas in between. Faint stars and interstellar gas account for the majority of the galaxy's mass, up to 98%, and dominate the dynamic state inside the galaxy.
5. Perfect spiral galaxy
The perfect spiral galaxy (NGC 628) is about 30 million light-years away from Earth and is the closest known spiral galaxy to perfection. It has more than 100 billion stars. Here is a photo of its front taken by the Hubble Space Telescope.
6. Straw Hat Galaxy
The Sombrero Galaxy (NGC 4594) is about 29 million light-years away from the Earth. It is named because the bright core bulges in the center of the galaxy and the cosmic dust near the core radiates around like the brim of a sombrero, making it look like a Mexican sombrero. .
7. Canes Whirlpool Galaxy
What makes the Canes Whirlpool Galaxy (NGC 5194), about 22 million light-years away from Earth, so striking is that it also has a companion yellow galaxy (NGC 5195) outside its spiral arms.
It looks like the former is pulling the latter, but in fact the gravitational waves accompanying the galaxy compress the gas clouds to the inner edges of the spiral arms of the spiral galaxies. These nebulae are like dark clouds. Dense nebulae allow star formation to occur, forming pink star-forming regions.
8. Black Eye Galaxy
The Black Eye Galaxy (NGC 4826) is about 17 million light-years away from Earth. It is named after a fascinating and spectacular dark dust lane that stretches in front of the bright galaxy core.
9. Ursa Major Spiral Galaxy
The Ursa Major Spiral Galaxy (NGC 3031) is about 12 million light-years away from the Earth. It is one of the brightest galaxies in the Earth's sky and is located in the northern direction of the Ursa Major constellation. It is the closest macrophase spiral galaxy to Earth. Pictured here is an infrared photo taken by the Spitzer Space Telescope.
10. Silver Dollar Galaxy in Sculptor
The Sculptor Galaxy (NGC 253), about 10 million light-years away from Earth, is one of the brightest and dustiest spiral galaxies visible in the sky. Some people observed its appearance with small telescopes and called it the Silver Dollar Galaxy; because it is located within the boundaries of the constellation Sculptor in the southern sky, it is also called the Sculptor Galaxy.
What are the names of galaxies?
1. Elliptical galaxy
The Hubble classification of galaxies classifies elliptical galaxies based on estimates of their ellipticity, from E0, nearly round, to E7, very elongated. These galaxies have an elliptical appearance regardless of the viewing angle. They appear to have no structure and contain relatively little interstellar matter. Typically these galaxies have a small number of open star clusters and a small number of newly formed stars, replaced by a predominance of older, mature stars orbiting the center of the galaxy in various directions. Some of their properties are similar to those of much smaller globular star clusters.
2. Spiral Galaxy
In spiral galaxies, the shape of the spiral arms approximates a logarithmic spiral, which is theoretically shown to be an interference pattern caused by the consistent rotation of a large number of stars. Like stars, spiral arms rotate around the center, but the angular rate of rotation is not constant, which means that the star will pass through the spiral arms, which are regions of high density or density waves. As stars enter the spiral arms, they slow down, creating higher densities; similar to how waves slow down cars on a highway.
3. Spiral Galaxy
(Spiral Galaxy, S-type Galaxy) Extragalactic galaxies with spiral structures are called spiral galaxies, and are represented by S in Hubble's galaxy classification. The spiral shape of a spiral galaxy was first discovered in 1845 when observing the Canes Canes galaxy M51. The central region of a spiral galaxy is lens-shaped, surrounded by a flat disk. Several spiral arms extend from both ends of the bulge and are superimposed on the galaxy disk. Spiral galaxies can be divided into two types: normal spiral galaxies and barred spiral galaxies.
4. Barred spiral galaxy
(Barred Sprial Galaxy, SB-type Galaxy) A barred spiral galaxy is a spiral galaxy with a long bar shape in the center. Generally, the center of a spiral galaxy has a round core, while a barred spiral galaxy has a bar-shaped center in the center. There are spiral arms extending outward on both sides.
5. Dwarf galaxies
Although elliptical and spiral galaxies are obvious and prominent, most galaxies in the universe are dwarf galaxies, tiny galaxies less than one percent the size of the Milky Way and containing only a few billion stars. Many dwarf galaxies may orbit single large galaxies, and our Milky Way contains at least a dozen such dwarf galaxies. Dwarf galaxies can similarly be divided into elliptical, spiral and irregular. Because dwarf elliptical galaxies are somewhat similar in appearance to larger elliptical galaxies, they are often called dwarf spheroidal galaxies instead.
6. Active galaxies
Some of the galaxies we observe are classified as active galaxies, which means that in addition to stars, dust and the interstellar medium, the total energy from the galaxy has another important source. The standard model of active galactic nuclei like this, based on the distribution of energy, suggests that material falls into a supermassive black hole at the core.
7. Irregular galaxies
Irregular Galaxy (Irr-type Galaxy) A galaxy with an irregular shape, no obvious core and spiral arms, no disk-like symmetry structure or no visible rotational symmetry, is represented by the letter Irr. Among the brightest galaxies in the sky, irregular galaxies account for only 5%. According to the galaxy classification method, irregular galaxies are divided into two categories: Irr type I and Irr II.
Extended information:
Galaxies vary greatly in size. The diameter of elliptical galaxies ranges from 3,300 to 490,000 light years; the diameter of spiral galaxies ranges from 16,000 to 160,000 light years; the diameter of irregular galaxies ranges from approximately 6,500 to 29,000 light years!
The mass of a galaxy is generally between 1 million and 1 trillion times the mass of the sun! (Note: The unit megabyte is an ancient Chinese term. Now it is generally considered to be 1 times 10 raised to the sixth power, which can easily cause ambiguity)
The stars inside the galaxy are moving, the galaxy itself is also rotating, and the entire galaxy is also moving in space. Traditionally, astronomers believed that galaxies rotate at the same rate, clockwise and counterclockwise. But according to the observations of Galaxyzoo, a distributed participation project for galaxy classification, there are more galaxies rotating counterclockwise!
Galaxies have a red shift phenomenon, which means that these galaxies are getting farther and farther away from us in the direction of space sight. This is also a strong evidence for the Big Bang theory.
The distribution of galaxies is nearly uniform on large scales; however, it is very uneven on small scales. For example, the Large Magellanic Cloud and the Small Magellanic Cloud form a double galaxy, and they form a triple galaxy with the Milky Way!
Galaxy is derived from the Greek γαλαξίας (galaxias). In a broad sense, a galaxy refers to an operating system composed of countless star systems (including stars themselves) and dust (such as nebulae, etc.). Consider the Milky Way, which is a large galaxy containing stars, interstellar matter of gas, cosmic dust and dark matter, and is bound by gravity.
Typical galaxies range from dwarf galaxies with only tens of millions of stars to elliptical galaxies with tens of millions of stars, all orbiting a center of mass. In addition to individual stars and thin interstellar matter, most galaxies contain a large number of multiple star systems, star clusters, and various types of nebulae.

The more names of planets related to science fiction, the better
1. The planet Cybertron. Cybertron is the home planet of the Transformers in the plot of "Transformers" (a series of toys, animations, movies, etc.) jointly developed by the United States and Japan. Cybertron, also translated as "Cybertron" or "Cybertron", is the home planet of the Transformers race. The American version is called Cybertron, and its entity is Primus, the creator god of the Transformers race. Cybertron orbits Alpha Centauri and is a giant metallic planet about the same size as Earth's neighbor Saturn. It is composed of a variety of metal ores with different properties, and is the home of powerful mechanical life forms that can transform their bodies between robot forms and various transformed forms. For millions of years, the main factions - the Autobots and the Decepticons. 2. Pandora Pandora is a fictional satellite in the movie "Avatar". The scientific name is "Alpha Centauri B-4", which is a planet in Alpha Centauri and is about the same size as the Earth. Pandora is not a planet, it is actually a satellite of a giant gas planet. 3. Death Star: A star mentioned in Liu Cixin's novel "Supernova Era". The star has a diameter of twenty-three times that of the sun and a mass of sixty-seven times that of the sun. It is entering its old age. 4. Vulcan Vulcan generally refers to the star Vulcan. Vulcan is the home planet of the Vulcans, one of the most important intelligent races in the universe and the interstellar federation in the American TV series "Star Trek" TV series. 5. Reach: Reach is a near-Earth colonial planet of humans in the best-selling game and novel "Halo". It is also the headquarters of the UNSC (United Nations Space Command). Because it is rich in titanium, the raw material of Class A titanium alloy, the main material used to make human space battleship armor, Reach is also the production base of UNSC large battleships.

Looking for the names and pictures of various planets. Thank you
Mercury (Mercury) was called Chenxing in ancient China. It is a terrestrial planet in the solar system and a rocky planet. It is mainly composed of stone and iron and has a high density. The rotation period is very long, 58.65 days, and the direction of rotation and revolution are the same. Mercury can orbit the sun once in 88 Earth days, with an average speed of 47.89km/s, making it the fastest moving planet in the solar system. No satellites orbiting. It is the smallest planet among the eight planets and the planet closest to the sun. Venus Venus is one of the eight planets in the solar system. It is the second planet in order of distance from the sun. It is the closest planet to Earth. In ancient China, it was called Changgeng, Qiming, Taibai or Taibai Venus. The orbital period is 224.71 Earth days. The brightness of Venus in the night sky is second only to the moon. Venus reaches its maximum brightness slightly before sunrise or after sunset. Sometimes it appears in the eastern sky before dawn and is called "Qiming"; sometimes it appears in the western sky after dusk and is called "Chang Geng". Earth The Earth is the third planet from the inside to the outside of the solar system. It is also the terrestrial planet with the largest diameter, mass and density in the solar system. The equatorial radius is 6378.2 kilometers, ranking fifth among planets in size. The Earth has an atmosphere and a magnetic field. 71% of its surface is covered by water and the rest is land. It is a blue planet. The earth is the home of millions of species of living things, including humans. It is also the only celestial body in the universe known to mankind that has life. The earth is 4.5 billion years old. There is a natural satellite, the moon, that rotates around the earth in a 27.32-day period. The earth rotates from west to east, rotates in a nearly 24-hour period and orbits the sun in a one-year period. Mars is one of the eight planets in the solar system. It is the fourth planet from the inside to the outside. It is a terrestrial planet with a diameter about half that of the Earth. Its rotation axis inclination and rotation period are both similar to those of the Earth. Its revolution is about Twice the Earth's revolution time. It is called "Mars, the God of War" in the West, and "Yinghuo" in China. The orange-red appearance is due to hematite (iron oxide) on the surface. Mars is basically a desert planet, with sand dunes and gravel all over the surface, and no stable liquid water. The atmosphere dominated by carbon dioxide is thin and cold, with sand and dust suspended in it, and dust storms often occur every year. Both poles of Mars have polar caps composed of water ice and dry ice, which wax and wane with the seasons. Jupiter Jupiter is one of the eight planets in the solar system. It is the fifth planet from the sun (from near to far). It is also the largest and fastest rotating planet in the solar system. Jupiter has 63 known satellites. Jupiter is mainly composed of hydrogen and helium, and its core temperature is estimated to be as high as 30,500°C. In ancient China, it was called the Sui Star because it took 12 years to orbit the celestial sphere, which was the same as the Earthly Branches. Western languages generally call it Jupiter (Latin: Jupiter), derived from the king of gods in Roman mythology, equivalent to Zeus in Greek mythology. Saturn Saturn is one of the eight planets in the solar system. It is the sixth in distance from the sun (from near to far) and is second only to Jupiter in size. And together with Jupiter, Uranus and Neptune, it is a gas (Jupiter-like) giant. In ancient China, it was also called Zhenxing or Star-filling. Saturn is mainly composed of hydrogen, with a small amount of helium and trace elements. The inner core consists of rock and ice, and the outer periphery is covered by several layers of metallic hydrogen and gas. The outermost atmosphere is usually bland in appearance, although long-lasting features sometimes appear. Saturn's wind speed is as high as 1,800 kilometers per hour, which is obviously faster than the wind on Jupiter. The strength of Saturn's planetary magnetic field is between that of Earth and the stronger Jupiter. Saturn has a significant ring system, the main component is ice particles and a smaller amount of rock debris and dust. There are 62 confirmed satellites of Saturn. Among them, Titan is the largest satellite in the Saturn system and the second largest satellite in the solar system (radius 2575KM) (the largest satellite in the solar system is Jupiter's Ganymede, with a radius of 2634KM), which is larger than Mercury among the planets; and Titan Six is the only satellite with a significant atmosphere. Uranus Uranus is the seventh planet from the sun. It is the third largest planet in the solar system (larger than Neptune) and the fourth largest planet in mass (lighter than Neptune). His name comes from the sky god Uranus (Οὐρανός) in ancient Greek mythology, the father of Cronus (the god of agriculture) and the grandfather of Zeus (Jupiter). Uranus is the first planet discovered in modern times. Although its luminosity is the same as that of the five traditional planets and its brightness is visible to the naked eye, it was not discovered by ancient observers because it was relatively dim. Sir William Herschel announced his discovery on March 13, 1781, extending the known limits of the solar system for the first time in its modern history. It was also the first planet discovered using a telescope. Neptune Neptune is the eighth planet orbiting the sun and the fourth largest celestial body (in diameter) orbiting the sun. Neptune is smaller in diameter than Uranus, but more massive. Neptune is about 17 times as massive as Earth, while twin Uranus is about 14 times as massive as Earth due to its lower density. Neptune is named after Neptunus in Roman mythology. Because Neptune is the god of the sea, it is translated into Chinese as Neptune. The symbol of astronomy is the trident used by Poseidon, the god of the sea in Greek mythology. Pluto Pluto, also known as asteroid 134340, was discovered in January 1930 by Clyde Tombaugh based on calculations by American astronomer Lowell and named after Pluto, the god of the underworld in Roman mythology. It was once one of the nine planets in the solar system, but was later downgraded to a dwarf planet. The average distance from the sun is 5.9 billion kilometers. It has a diameter of 2300 kilometers, an average density of 0.8 grams/cubic centimeter, and a mass of 1.290×10^22 kilograms. The revolution period is about 248 years and the rotation period is 6.387 days. The surface temperature is below -220°C, and there may be a layer of solid methane ice on the surface. There are four satellites tentatively discovered. Since the day it was discovered more than 70 years ago, Pluto has been associated with the word "controversy". First, because the process of its discovery was based on a wrong theory; second, because its mass was originally estimated incorrectly, and its mass was mistakenly estimated. It is included in the ranks of major planets. In 1930, American astronomer Tombaugh discovered Pluto. At that time, he misestimated the mass of Pluto and thought that Pluto was larger than the earth, so he named it a giant planet. However, after nearly 30 years of further observation, it was found that its diameter is only 2,300 kilometers, smaller than the moon. When Pluto's size is confirmed, "Pluto is a large planet" has long been written into textbooks, and it will be wrong in the future. Pluto's orbit is the most oblate, so that in the past 20 years, Pluto has been closer to the sun than Neptune. From its discovery to now, people have only seen it travel less than 1/4 of its orbit, so little is known about it in the past. Pluto's mass is much smaller than that of other planets, and even among the satellite worlds it only ranks around seventh or eighth. The surface temperature of Pluto is very low, so most of the materials on it can only be solid or liquid, that is, its ice mantle is extremely thick. Only hydrogen, helium, and neon can remain in the gaseous state. If there is an atmosphere on it, it can only be composed of these three types. Elemental composition. In the 21st century, improvements in astronomical telescope technology have enabled people to gain a deeper understanding of trans-Neptunian objects. In 2002, an asteroid named 50000 Quaoar was discovered. The diameter of this newly discovered asteroid (1280 kilometers) is longer than half the diameter of Pluto. In 2004, the maximum diameter of the asteroid named 90377 Sedna reached 1,800 kilometers, while the diameter of Pluto was only about 2,320 kilometers. On July 9, 2005, another newly discovered trans-Neptunian object was announced to be officially named Eris. Eris's brightness and albedo indicate that it is slightly larger than Pluto. It is the largest object discovered in the solar system since the discovery of Neptune in 1846. Although there was no official consensus, its discoverers and numerous media outlets initially dubbed it the "tenth planet." Some astronomers believe that the discovery of Eris provides strong evidence for reconsidering Pluto's planetary status. Even Pluto's distinguishing features, its moons and atmosphere, are not unique. Some asteroids in the trans-Neptune belt also have their own moons. Moreover, the celestial spectrum analysis of Eris also shows that it has a similar surface to Pluto. In addition, Eris also has a larger satellite, Dysnomia. "Star status" controversy And Pluto meets the third planetary criterion above. The International Astronomical Union further decided that Pluto should be classified as a dwarf planet and could serve as the prototype of an as-yet-unnamed class of trans-Neptunian objects. Before this resolution, people had also proposed different planetary plans, some of which even mentioned disqualifying Mars and Mercury from being planets in addition to Pluto, while others proposed including some asteroids as planets.

Names of all the galaxies in the universe
Open your eyes and look around the entire universe, it is vast. What is there in the universe? The earth we live on is a large planet from the sun. The nine major planets in the solar system, arranged from the inside out with the sun as the center, are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Except for Mercury and Venus, the other seven planets have their own satellites. Currently, there are nearly 50 satellites discovered in the solar system. In the solar system, there are also numerous asteroids, comets, meteors and meteorites. So, what else is there outside the solar system? On a clear night, the sky is filled with stars, of which stars make up the majority. A star is a celestial body that can emit light by itself, like the sun. There are hundreds of billions of stars in our galaxy alone. Stars vary greatly in size, luminosity, mass and density. Some stars are very bright, with luminosity hundreds to ten thousand times greater than the sun. Such stars are called giant stars. Some stars are tens of thousands to millions of times brighter than the sun, and their radii can exceed a thousand times the sun. They are called supergiants. There is also a type of white star with low luminosity, small size and extremely high density called a white dwarf. The luminosity of some white dwarfs is as small as tens of thousands of times that of the sun, and their volume is only a few tenths of that of the Earth, but their density is as high as hundreds of kilograms, several tons or even thousands of tons per cubic centimeter. More than 1,000 white dwarfs have been discovered so far, and it is estimated that there are 10 billion white dwarfs in our Milky Way alone. In 1967, people discovered a rapidly rotating neutron star, also called a pulsar. Neutron stars are the smallest dwarfs among stars. Most neutron stars are only about 10 kilometers in diameter, but their density is astonishingly high, reaching 100 million tons per cubic centimeter. If a 10,000-ton giant ship is used to tow it, 1 cubic centimeter of material on the neutron star will Need 1
The most beautiful galaxy name in the universe
No one knows how many galaxies there are in the universe. Hubble divided them into three major categories based on their shapes: elliptical galaxies, spiral galaxies and irregular galaxies. Elliptical galaxies are divided into seven types. According to the oblateness of the galaxy ellipse, they are represented by E0-E7 from small to large. The maximum value of 7 is determined arbitrarily. This classification is limited to the appearance of galaxies as seen from Earth because it is difficult to determine the angle of an elliptical galaxy in space. Spiral galaxies are divided into two groups, one is a barred spiral galaxy with a central bar structure, represented by SB; the other is a spiral galaxy without a bar structure, represented by S. These two types of galaxies are subdivided into three subtypes, with the subscripts a, b, and c indicating the size of the galaxy core and the tightness of the spiral arm winding. Irregular galaxies have no definite shape and contain more dust and gas, represented by Irr. There is another type of lenticular galaxy represented by S0, which represents a galaxy in the transitional stage between elliptical galaxies and spiral galaxies.
