In the Universe there are a huge number of galaxies, the study of which at the moment is not possible. A person who does not have a telescope also has the opportunity to see galaxies. But how many of them can he see with his eyes?
When galaxies appeared
According to preliminary estimates, the universe appeared 13.8 billion years ago due to the explosion of a singularity, which was a small sphere. From that moment, the space around began to expand rapidly, forming space.
Interesting fact: 380 thousand years later, molecules capable of creating materials and objects began to form in the Universe.
The first galaxies and stars began to form only after 300 million years. Moreover, they began to acquire a modern look after billions of years. Some galaxies have taken the form of spiral disks, while others have spherical structures.
The exact number of galaxies in the universe is unknown, but it is estimated that there are about two trillion of them.
How many galaxies can the human eye see?
You can see any galaxies only in the sky, where the stars are clearly visible. It is impossible to observe them in the urban area, since the light from the streets, houses and advertising signs covers the luster of stars.
And if a person is, for example, in a clean field, and he can see all the stars in the sky, then he able to view six galaxies.
Milky Way - the galaxy where the solar system is located.Accordingly, most of the stars around are part of its composition.
Big Magellanic Cloud - The dwarf galaxy, which is the satellite of the Milky Way, is located at a distance of 163 thousand light years.
Small Magellanic Cloud - Another satellite of the Milky Way, which includes one and a half billion stars.
Andromeda - A large galaxy located in the constellation of the same name. It is the closest to the solar system and is located at a distance of 2.52 million light years.
Triangle - known for the largest black hole, whose mass is 16 times greater than that of the Sun.
Bode - Located in Ursa Major, it is considered a spiral galaxy of perfect shape.
To observe more distant galaxies, binoculars or a telescope are already required.
The human eye can see six galaxies: the Milky Way, Big and Small Magellanic clouds, Andromeda, Triangle and Bode.
