The universe is composed of different galaxies each having their own unique peculiarities. There are however dozens of questions that would arise as far as the galaxies are concerned and one of such questions bothers on which galaxy arms extend from a core full of black holes. We will attempt to answer these question and others.
Which galaxy arms extend from a core full of black holes?
The name of the galaxy arm that extends from a core full of black holes is known as a spiral galaxy. The existing theory is that there exists a very large black hole located in the middle of each Galaxy. If this is the case, then each galaxy arm will extend starting from the accretion disk within a large black hole. As it stands, the Milky Way seems to possess a large gravitational object in the middle which is believed by several people to be a black hole. The arms of the Galaxy we find ourselves tend to sweep around the middle.
Are There Black Holes Inside The Galaxies?
The answer is a big yes! The majority of the large galaxies such as Andromeda or the Milky Way usually have a large black hole located at their core. Within the arm of our galaxy, you will find several thousands of black holes. Hence, it suffices to say that black holes can be found in galaxies. In Theory, a Blackhole will not be able to form out of a galaxy because a superstar is usually needed to create a black hole. Usually, such superstars will never form outside of a cluster of stars.
What Exactly Is A Galaxy?
When defining planet earth, we usually factor in things like gravity, the atmosphere, the core as well as the surface. Planet earth is made up of diverse ecosystems that range from steamy and hot to blustery and cold depending on their distance to the sun. it should also be noted that the same way we have a dense population of people in the same way we have a dense population of stars. Also, the same way our planet has its mix of materials suited for the earth is the same way the galaxy is made up of dust, gas, and stars peculiar to the galaxies.
Though we have different galaxy types, the same way we have different nations, each one of the galaxies come with their unique peculiarities. There are quite several galaxies existing within our universe with each one having its unique blend of gases and systems. You also find black holes within different galaxies, a strange phenomenon that drags everything that comes too close.
The way and manner the galaxies move make one believe that they were all bound together at some point and something massive like a big bang occurred. It is believed that this occurrence leads to the galaxies moving away from one another.
What Are The Different Types Of Galaxies?
Within the universe wherein we find ourselves, there are four known types of galaxies. These galaxies are made up of dust, stars and gas bound together by forces of gravity. The galaxies are all named by their shape, thus making it quite easy to recognize the type of galaxy.
By now you may be quite familiar with some of the galaxies namely the barred spiral, spiral, irregular, and elliptical. All of these galaxies were created from a combination of matter and gas which combined and painted out unique galaxies with their unique peculiarities.
There are four different types of galaxies namely the irregular, elliptical, spiral, and spiral barred. Even though there are diverse types of galaxies, we are made to understand that each one of these galaxies is composed of the same elements. However, they are arranged differently. It, therefore, suffices to say that the galaxies are designed with stars, gasses, dust and the likes uniquely.
Here is a breakdown of the classification:
1. Spiral Galaxy
You can easily identify these based on three distinct features that are peculiar to every spiral galaxy. Each Spiral Galaxy contains a bulge, a disk as well as a halo. The middle of the galaxy is more like a nucleus which contains a bulge shaped like a sphere that contains old stars and does not have old stars and gas. The galaxy arms are known to originate from the disk and this is the place where the new stars are formed within the galaxy.
The sun that powers planet earth can be found within one of the arms and its stars are formed within this galaxy portion which is known to contain most of the gases within the galaxy. This area is loaded with blue stars. A Halo is simply a collection of old clusters and stars which are referred to as the globular clusters which are located in the outer edge of the same galaxy.
2. Barred Spiral Galaxy
It is on record that barred galaxies have the same functions and features as the normal spiral galaxies. They however also possess a collection of bright stars that are located along the middle of the bulge and go further into the disk. This bright bulge usually has less activity and more often than not contains older and red stars. However, the arms and bars are involved in a lot of activities such as star formation.
Even though the classification reserved for barred spirals is the same as for the regular spiral galaxies, it is still important to consider the bars. Usually, the shorter bars tend to correlate with the tighter galaxies.
3. Elliptical Galaxy
You will be able to easily recognize this type of galaxy because of their elongated spherical shapes as well as the absence of a nucleus in the middle. Even though it does not have a nucleus, the galaxy is still very much bright in the middle and diminishes in brightness as you go outwards of the galaxy. Gases, stars and some other materials are spread over the elliptical galaxy. It is usually shaped round or in a cigar kind of shape.
It is a general belief that a large amount of the mass within an elliptical galaxy is usually as a result of the presence of a black hole. Such galaxies usually have lower levels of activity and mostly contain old stars possessing low mass because the dust and gasses needed to create new stars are missing.
4. Irregular Galaxy
These types of Galaxies are made up of stars, dust, neutron stars, nebulous formation, and several other elements. The name irregular galaxies are a result of the fact that they do not have a defined shape. However, as in the case of all galaxies, they are usually in motion moving far from the universe. They are classified into two namely the IO and IM.
IM galaxies usually happen among irregular galaxies and could indicate signs of spray arms. On the other hand, the IO galaxies are called chaotic because they are quite random.
What Are The Properties Of Galaxies?
Magnetic fields: it should be noted that Galaxies possess magnetic fields which are so strong that it makes them dynamic. This gives them the ability to make mass flow come towards the middle of the galaxies. They are also able to modify the creation of spiral arms and they may usually cause an effect on the gas rotation in the outer parts of the galaxies.
What Are The Types Of Galaxies?
There are several types of galaxies depending on certain factors. These galaxies include the Starburst, the active galaxy, Blazers, liners, Seyfert, Quasar, and the luminous infrared galaxy.
What Are Black Holes?
Black holes are simply large swath of space where the force of gravity is strong enough to prevent even the quickest object from escaping. What this means is that not even light can escape the black hole.
How Are Black Holes Formed?
It is a generally accepted fact that stars that possess a mass of about three times the mass of the sun can go through rather extreme gravitational effect the moment the fuel finishes. In a situation where a large mass is limited to space, the overall gravitational force overcomes the theory that prevents atoms from occupying the same confined area. This density is what brings about the black hole.
Another type of black hole has been muted even though it has not been observed. It is believed that they were created when the vacuum of the initial universe increased rapidly, therefore, leading to the collapse of dense regions. This type of black holes is known as primordial black holes and usually has a smaller mass that can be likened to that of the earth.
Conclusion
Having discovered which galaxy arms extend from a core full of black holes, it is imperative to recognize that black holes are a phenomenon we will keep researching. Since the galaxies possess their black holes and each galaxy being a world of its own, we will surely keep updating you with the latest developments.
