a trip around the galaxies

There were many different types of galaxies in the universe. According to Hubble's classification, galaxies could be divided into oval galaxies, spiral galaxies (including barred spiral galaxies), irregular galaxies, and other types. In addition, there were active galaxies such as starburst galaxies. Elliptical galaxies were more common and shaped like spheres. They were often formed by collisions and amalgamations between galaxies. They could be very large in size and had no galactic core in the center. They were mainly composed of old stars with relatively little dust and gas. Spiral galaxies were like vortexes. They usually had an obvious core, with more than two spiral arms around the core. There were more dust and gas clouds in the galaxy. The Milky Way was a spiral galaxy among spiral galaxies. Irregular galaxies did not have a fixed shape. They might have been formed by the collision of other galaxies or the distortion of their original shape due to gravity. They accounted for about a quarter of all galaxies. From the scale of the galaxy, the galaxy contained many stars, interstellar gas, dust, dark matter, and so on. The number of stars ranged from billions to hundreds of billions. The distance between galaxies was calculated in light years. Within the range of modern observation methods, it was estimated that there were at least 1 billion galaxies. A dozen or even thousands of galaxies could form a galaxy cluster, which was a larger structure in the universe with dynamic constraints. There were about 40 galaxies in the Local Galaxy Group where the Milky Way was located, including the Andromeda Galaxy, the Magellanic Cloud, and the Triangular Galaxy. The Local Galaxy Group was also a member of the Local Supercluster with the Virgo Cluster as the center. The closest galaxies to the Milky Way were the Large Magellanic Cloud and the Small Magellanic Cloud, about 170,000 and 200,000 light-years away from Earth respectively. The larger galaxies that were closer to the Milky Way were the Andromeda Galaxy, 2.56 million light-years away. The novel "The Name Engraved in the Stars of Destiny" is equally exciting.

In the existing galaxy names, there was no specific mention of galaxy names with specific meanings. Most of them were named according to their shape, constellation position, or order of discovery. For example, the oval galaxies were named according to the flattening (E0 - E7), and the spiral galaxies were divided into the spiral galaxies (S) and the spiral galaxies (S) according to the existence of the rod structure. The sub-types were further divided according to the size of the nucleus and the tightness of the spiral arms. Some were named after their constellations (such as NGC4552 in Virgo). Therefore, from the information retrieved so far, it was impossible to determine which galaxy names had a meaning. The novel "The Name Engraved in the Stars of Destiny" is equally exciting.
