The galaxies They are structures composed of billions of stars, gas, dust and dark matter that are held together gravitationally. In the vast universe, there are countless galaxies, but some stand out for their popularity and recognition. Next, we will present the 5 best known galaxies and we will reveal their names.
1. Milky Way: The Milky Way is the galaxy in which our solar system is located. It is shaped like a disk and contains about 200 billion stars. It is also home to planets, asteroids, comets, and clouds of gas and dust. The Milky Way is visible from Earth as a band of light in the night sky.
2. Andromeda: The Andromeda galaxy is the closest galaxy to the Milky Way. It is located about 2.5 million light years away and is visible to the naked eye from Earth. Andromeda is a spiral galaxy similar to the Milky Way and contains about 1 billion stars.
3. Triangle Galaxy: The Triangle galaxy, also known as M33, is located in the Triangle constellation. It is a spiral galaxy like the Milky Way and Andromeda. The Triangle galaxy is visible with small telescopes and contains about 40 billion stars.
4. Centaurus A: Centaurus A is a peculiar galaxy located in the constellation Centaurus. Unlike the other galaxies mentioned, Centaurus A is an elliptical galaxy with an active central region and a jet of matter ejected from its core. It contains about 100 billion stars.
5. Hat: The Sombrero galaxy, also known as M104, is a spiral galaxy located in the constellation Virgo. Its peculiar shape gives it the name «Sombrero», since it looks like a top hat when seen in profile. It contains about 100 billion stars and is visible with telescopes.
These are just the 5 best known galaxies, but the universe is vast and full of wonders to discover. Each galaxy has its own name and unique characteristics that make them fascinating and impressive. Exploring the universe and learning about these galaxies helps us understand the vastness and diversity of the cosmos in which we live.

What are the 5 galaxies?
The galaxies They are vast star systems containing a large number of stars, planets, gases and cosmic dust. The universe is full of these fascinating structures that allow us to explore and better understand the cosmos.
The Milky Way is one of the galaxies best known and is the home of our solar system. It contains billions of stars, including our sun, and a wide variety of celestial bodies. The Milky Way has a spiral shape and is one of the key elements in the study of astronomy.
The Andromeda Galaxy, also known as M31, is the closest galaxy to the Milky Way and is visible to the naked eye in the night sky. It is a spiral galaxy similar to ours and has a diameter of approximately 220,000 light years. It is made up of billions of stars and is an important object in the study of cosmology.
The Triangle Galaxy, or M33, is another spiral galaxy close to the Milky Way. It is smaller than the Milky Way and Andromeda, but still contains a considerable number of stars and other celestial bodies. It is one of the few galaxies that can be observed directly without the help of telescopes.
The Sombrero Galaxy, or M104, is an elliptical galaxy located about 30 million light years away from Earth. Its name is due to its distinctive appearance, which resembles a wide-brimmed hat. This galaxy is known for hosting a supermassive black hole at its center and has been the subject of numerous investigations.
Finally, the whirlpool galaxy, or M51, is a spiral galaxy located approximately 23 million light years away. It is famous for its interaction with a small satellite galaxy, which has created a phenomenon known as a tidal bridge. Studying these interactions provides us with valuable information about the formation and evolution of galaxies.
What are all the galaxies called?
What are all the galaxies called?
The galaxies They are enormous groupings of stars, planets, gas and cosmic dust that are scattered throughout the universe. They are fascinating structures that have been studied for centuries.
There are different types of galaxies and, therefore, different names for each of them. Some of the best known galaxies are:
- Milky Way: It is the galaxy in which our solar system is located. Its name comes from Greek mythology, where it was believed to be the «way» along which the gods walked to Olympus.
- Andromeda: Also known as M31, it is the closest galaxy to the Milky Way. Its name comes from the Andromeda constellation, in which it can be easily observed.
- Hat: It is a peculiarly shaped galaxy that resembles a Mexican hat. Its full name is M104 and it is one of the most famous objects in the Messier Catalog.
However, these are just some of the galaxies better known. The universe is filled with billions of galaxies, each with its own name and unique characteristics.
Scientists use various methods to classify and name galaxies, taking into account their shape, size and composition. This has led to the creation of catalogs such as the Messier Catalog and the NGC Catalog (New General Catalogue), among others.
In summary, the galaxies They have varied names that reflect their diversity and uniqueness in the vast universe. Studying them and understanding how they work is one of the most exciting challenges in astronomy.
How many known galaxies are there in the universe?
The universe It is a vast space that houses a large number of celestial objects, including galaxies. But how many known galaxies are there in the universe?
The answer to this question is really surprising. According to the studies carried out to date, it is estimated that there are about 100 billion galaxies in the observable universe. However, it should be noted that this figure is only an estimate and that the universe is so vast that it can host many more galaxies yet to be discovered.
To understand the magnitude of this figure, it is important to note that our own galaxy, the Milky Way, is just one of many. Furthermore, galaxies are not all the same, there are different types such as spirals, ellipticals, irregulars, among others.
The study of galaxies is a branch of astronomy that has developed widely in recent years. Thanks to technological advances, such as space telescopes, astronomers have been able to observe and study a large number of galaxies, which has allowed them to obtain data and knowledge about the composition, evolution and characteristics of these celestial structures.
In summary, although the total number of galaxies in the universe cannot be known exactly, it is estimated that there are at least 100 billion known galaxies. This shows us the immensity and diversity of the cosmos, full of wonders to discover.
What are the 40 galaxies called?
What are the 40 galaxies called?
The universe is full of wonders, and the galaxies They are one of the most fascinating phenomena that exist. Each galaxy It is unique and carries with it a special name. Here we present some names of the 40 galaxies better known.
1. Andromeda: The galaxy closest to the Milky Way and one of the largest known.
2. Milky Way: Our own galaxy where our solar system is located.
3. Triangle: One of the galaxies brighter and easily visible in the night sky.
4. Swirl: A galaxy beautiful spiral and recognizable by its characteristic shape.
5. Owl: A small galaxy which resembles the shape of this nocturnal animal.
6. Centaur A: One of the galaxies closer and with a supermassive black hole at its center.
7. Elliptical: A galaxy with an elliptical shape and little or no visible disc.
8. M51: Also known as the Whirlpool Galaxyit is a system of two galaxies in interaction.
These are just a few examples, but there are many more. galaxies with fascinating names. Each galaxy It has its own history, characteristics and mysteries to discover. Exploring the universe is an incredible journey to learn and marvel at the immensity of the cosmos.
