Types of galaxy and name of galaxy – Essentially, the planet we dwell on is one of several in the Solar System. The Solar System contains not only planets, such as Earth, but also satellites, meteors, comets, and asteroids, as well as millions of stars from the group of galaxies. So we live in a galaxy, right? Yes, you are accurate.
There isn’t only one galaxies in the cosmos, you know… but galaxies are numerous, it’s just that our understanding is still restricted and only knows hundreds. Nonetheless, anthropology is already at ease at this point, because it knows the name of the galaxy that exists!
So, precisely what is a galaxy? What do the galaxies in our universe have names? What is the explanation behind the process of galaxy creation, which is unquestionably distinct from the process of solar system development?
What is Galaxy?
A galaxy is a massive stellar system made up of numerous stars. These stars are usually single stars or star clusters, but there are also planets, clusters, nebulae, asteroids, comets, gas, and cosmic dust. Please keep in mind that the Earth is not a sort of star because it cannot produce its own light.
You have also been aware that the Sun is the core of our solar system. The Sun, like the other planets, including the Earth, spins in its orbit or galaxy. This galaxy is also known as the Milky Way Galaxy. As a result, all humans living on Earth are part of the Milky Way galaxy.
In the galaxies that exist across the cosmos, there are billions of stars and celestial bodies of various sorts, some of which are red and white stars. Because the space between stars is so great, the cosmos appears “empty.” However, there are several tens of thousands of stars that appear to be “near together” around a centre, giving the impression of fog when observed.
The Galaxy’s Characteristics
Many individuals are unable to distinguish between a galaxy and a cosmic fog or a regular nebula. So, here are some of the properties of galaxies.
- A galaxy with its own light that is not reflected (fluorescence). Furthermore, the light would create an absorption spectrum suggesting that the emitting item is a solid surrounded by some gas.
- A galaxy having a distinctive form and a brilliant core at its centre, making it simple to identify.
- A galaxy that, no matter how far it is from the Sun, will be visible beyond the path of the dark Saryu star.
Types of galaxy
Galaxies seen across the cosmos may be categorised into various categories based on their size, namely:
Types of galaxy – Spiral galaxy
Because most galaxies are shaped like this, this is the most well-known kind of galaxy. The major components of this sort of galaxy are known as the bulge and halo. The bulge is the core component of the galaxy that protrudes and is solid. Although the Milky Way galaxy’s core is in the direction of Sagittarius, human eyes cannot view it directly. The halo, on the other hand, is a component of the spiral arm.
As the galaxy’s centre line or core, spiral galaxies typically have stellar vortices and stars of significantly older ages in the interstellar medium. This galaxy’s stars include both young and elderly stars.
Because of their spiral shape, spiral galaxies spin much faster than elliptical galaxies. Its rotating motion can also flatten and generate galactic planes in these galaxies. Because the size of the rotation speed is determined by the mass of the galaxy, not all spiral galaxies rotate at the same rate. M31 (Andromeda), M33 (Triangle), and M51 are examples of spiral galaxies (Whirlpool).
Types of galaxy – Elliptical galaxy
This sort of galaxy can range in form from roughly spherical to practically flat. An elliptical galaxy is a form of galaxy that seems softer because to strong light in the interstellar, making practically its whole shape look flat and bright. The number of stars in this sort of galaxy will almost probably be affected by its various sizes.
Edwin Hubble coined this categorization of galaxies in the Hubble Classification Scheme. M32, M49, and M59 are examples of this kind of galaxy.
Types of galaxy – Erratic galaxy
This form of galaxy is named from the fact that its shape is neither spiral nor elliptical, however there are many other shapes. Some are referred to as dwarf galaxies because they are smaller than typical galaxies, such as M110. Some of the others are known as ring galaxies because they are formed like a ring with a centre, with Hong being an example. NGC 5866 Hg is an example of a lenticular galaxy, which has a form that is a blend of spiral and elliptical.
Galaxies that lack this distinctive form often include interstellar material made up of gas and dust, but they also contain young and ancient stars. Another example of this sort of galaxy is the Large Magellanic Cloud and the Large Magellanic Cloud, which are located close to our Milky Way galaxy, around 180,000 light-years distant.
Name of galaxy in the universe
Milky Way Galaxy
This spiral galaxy is where we, along with other humans on Earth, reside. Yes, the Milky Way Galaxy, like other galaxies, is made up of billions of stars, cosmic fog, dust, and cosmic gases, the distribution of which is unequal. This galaxy’s collection of stars may be viewed with the naked eye, especially at night. The Milky Way galaxy’s core is a tremendously brilliant area engulfed in the first haze and generally observable only in radio wavelengths (infrared). Stars and stellar material will grow to form a plate with a diameter of around 80,000 light-years around the centre.
The Andromeda Galaxy is another well-known galaxy to the general population since it can be seen without a telescope. The Andromeda Galaxy is spiral-shaped like ours, and the distance between the two is around 2.5 million light years. Messier 31 is another name for the Andromeda Galaxy (M.31). Messier was a French astronomer who discovered this galaxy while researching the presence of galaxies in the cosmos.
The Big and Minor Magellanic Galaxies
Both of these galaxies lie in the Southern Hemisphere, around 150,000 light-years away from the Milky Way galaxy. These nearby objects are frequently thought to be satellites of our galaxy. The second name, Magellan, is taken from its creator, Ferdinand Magellan, a Portuguese astronomer.
Because this galaxy often circles the Milky Way galaxy, many people believe the two galaxies are part of our Milky Way system when they are not.
This galaxy has a spiral form that resembles a sombrero cap, thus the name. Messier 104 (M104) is another name for the Sombrero Galaxy, which is around 28 million light-years away from our galaxy. The core of this galaxy is exceptionally luminous, being at the centre of its massive bulge and encircled from the start.
Professional astronomers are fascinated by the large bulge, which is supposed to be the heart of a supermassive black hole.
This galaxy is named from its rose-shaped shape and location in the constellation Andromeda. The Rose Galaxy is really made up of two galaxies, UGC 1810 and UGC 1813. It is bigger and has a rose-shaped disc in UGC 1810. Then there’s UGC 1810, which is smaller and exhibits numerous signals of a usually active star production process.
The spiral galaxy NGC 253 is claimed to be the brightest and darkest galaxy. Sculptor is a southern constellation located around 8 million light-years distant. The Sculptor galaxy is dense in dust, with dust cells frequently seen rising from the galaxy’s disc.
Black Eye galaxy
This galaxy is so named because it features a black zone in front of its light nucleus that is great at absorbing dust. The black band is thought to be the consequence of a collision with another galaxy. This galaxy, like the Sombrero Galaxy, was discovered by Charles Messier, a French astronomer.
Blue Wheel Galaxy
This galaxy is spherical, like a blue wheel, as the name implies. This galaxy is around 2 million light years distant from our own. Because this galaxy is so close to the Milky Way, its members may be viewed by humans on Earth using binoculars or special binoculars.
The form is quite distinctive, resembling the wheels of a rowed waggon, and the distance is around 150,000 light years. This cartwheel galaxy features an extremely bright core with a debut bar and thin gas leading to a ring of stars surrounding it.
The distance from Earth is approximately 500 million light years, and it is located in the constellation Sculptor. Its unusual form is thought to have resulted from a direct cosmic impact millions of years ago.
The arrangement of the spiral arms of the galaxy Messier 63, as seen in this new Hubble Space Telescope image, is similar to the pattern in the core of a sunflower.
Messier 63 is known by another name because of its sunflower-like form (M63). This galaxy, like the Sombrero and Black Eye galaxies, was discovered in 1781 by Charles Messier. Because it is a spiral with numerous sides, it will resemble a sunflower design.
The distance from Earth is approximately 27 million light years in the constellation Canes Venetisi. The strong light that frequently lights this galaxy is caused by a newly born big blue and white star.
M101 Ursa Major Galaxy
This galaxy is also known as the Big Dipper Galaxy. The existence of this galaxy is extremely beneficial to humanity on Earth, particularly sailors who use it as a reference point when sailing tonight. Not only that, but the appearance of the Ursa Meyer Galaxy is frequently considered a marker of the birth of the rice moniker.
At first look, this galaxy appears to have the tip of a very brilliant star, therefore it may undoubtedly be used as a reference point when sailing. This galaxy has six stars and may be seen in the sky above the North Pole.
It appears to be a vortex generated by a gravitational disturbance in the cosmos. Grammedes could readily discover this galaxy if he gazed up at the stars with binoculars. Astronomers frequently use the Whirlpool Galaxy, also known as M51, as a target in their efforts to investigate the galaxy’s structure and spiral arms.
