All you need to know about Galaxies




The term: “Galaxies” comes from the ancient Greek civilization, who attributed the origin of a galaxy to the drops of milk poured into the universe by the breasts of the goddess Hera while feeding her son the god Hercules.

Galaxies are the highest level of organization in the universe, all celestial bodies and known elements converge in a harmonized system like for example: Stars, clouds of gas, planets, cosmic dust, dark matter and energy United Gravitationally with a more or less defined structure, these bodies and elements move together around the very nucleus of the galaxy.

How many galaxies are in the universe

The Basto universe is a place of infinite proportions, therefore, everything that exists in it is usually of colossal size, or in other words we could say, it is composed of numerous elements, which exceed the numerical units of million.

Such is the case of the highest level of organization in the universe: galaxies, which already have a significant number of celestial bodies, such cosmic organizations are not so unique, since according to studies published in 2016, it is estimated that there are no Less than 2 trillion of galaxies, i.e. two million millions, in the observable universe.

Types of galaxies that exist

With the support of new technologies and informatics, cosmic exploration programs have compiled important information about the configuration of the giant galaxies found in the universe. So, we can say that there are four large groups of them and are: elliptical, spiral, lenticular and irregular, this classification is based on the shape they have.

The Ellipse Galaxy. They may have a type of nomenclature: from E0 to E7, in which the numerical term refers to how oval the ellipse is; Thus, E0 would be a form of sphere and E7 of plate or disc.

The spiral galaxy: it is that formation in rotating disc of stars and interstellar matter, these have a central protuberance that is basically comprised of the older stars. From this bulge, a spiral-shaped arms revolve on its axis.

The Lenticular Galaxy: These are the systems that present a form of transition between the elliptical galaxies and the spirals. They have a disc, a very important central condensation and an extensive sheath.

The irregular Galaxy: This is a galaxy that does not fit in any previous classification of galaxies, they are systems without spiral or elliptical form.

How many galaxies have been discovered




Galaxies

To date, more than 2 million million galaxies have been discovered in the Basto universe, according to the Space exploration program: Hubble. This corresponds to about ten times more than previously thought existed in the universe, this measurement has been collated with various space research agencies.

Based on the above, it is absolutely probable that the number will increase, since the trillion of galaxies discovered up to these times corresponds to the universe observable by our eyes and advanced robotic equipment. Thus leaving a wide and clear margin of possibility that there are many more galactic systems in the infinite space.
Why galaxies are flat

Galaxies are a system in which a number of celestial elements and bodies converge, clouds of gas, planets, cosmic dust, dark matter, and energy that are attracted by the gravitational force of the shining nucleus of the galaxy itself.

This set of elements were grouped with slow colossal movements, but hyper-fast to our perception to scale, after the conformation of the universe itself. The galaxies, regardless of their form, in most cases are flat because of the settlement and coupling of the celestial bodies that make it because of their own gravitational power.
