today that the name of our galaxy, any schoolboy knows.But it was not always.Milky Way - a huge empire, consisting of hundreds of billions of gravitationally bound stellar systems - Space is our homeland.It has always attracted the attention of mankind and caused him intense interest.Almost all ancient peoples and states existed its own answer to the question of the name of our galaxy.
In some countries of the ancient world called the Milky Way Dear Gods, in others - Star Bridge.For example, in ancient China used the name "Heavenly River".Unity in the matter did not exist.But in any case, in all corners of the ancient world the Milky Way was considered sacred.In his honor built temples worshiped.
scientific study of the history of the Milky Way is at least two thousand years.And now considered unthinkable not know the name of our galaxy, as the fateful question of how life began and what awaits us in the future, are inseparable from the concept.Only in the foreseeable part of the universe, there are about two hundred billion galaxies.
Each of them is unique in its structure, is huge in size and is constantly in motion.Galaxy aggressive.They are born as a result of grand cosmic catastrophes and die a violent death.Galaxy - a real stellar nurseries.Star, give life to our universe, illuminating, and it is heated, are born in huge galactic cluster of gas and dust of the construction material of the heavenly bodies.
One such incredible gigantic cosmic formations and our star is a house - the Milky Way.Most of the scientific history of unity on the question of how our galaxy is called, was not.Moreover, for a long time, scientists believed the Milky Way galaxy only one in the universe, a sort of island of prosperity in a vast cosmic ocean and lifeless.
But in 1924, Erwin Hubble to observe the starry sky with the help of the most advanced telescopes of the time, it changed the general idea.He noted deep in space obscure clubs of light and concluded that he had found no single objects, and the whole stellar conglomerates outside the Milky Way.Thus, the Hubble has revolutionized astronomy and brought a new level of studies of the structure of our galactic home.
Milky Way belongs to a spiraling, the most common type of star clusters.The structure of our galaxy and the great mysteries of the universe are now becoming more accessible to human eyes, thanks to modern telescopes and space unmanned, regularly transmitted to Earth the data collected.
So, we have learned that the distribution of stars is a characteristic and a distinct feature of which is that their concentration as they approach the galactic center is greatly enhanced.This allowed the scientists to make a conclusion about the presence in the heart of supermassive body possessing incredibly powerful gravity.
center of our galaxy located in the constellation Sagittarius, it seems, busy monstrous black hole.In any case, the only reasonable explanation is that modern science can provide a distribution of stars.In the future, our galaxy is waiting for a powerful cosmic cataclysm - a collision with the Andromeda galaxy, towards which we are rapidly rushing.As a result of this disaster Andromeda, far exceeds the size of the Milky Way, our star will absorb the monastery, which will cease to exist, but instead formed a new galaxy.And the evolution of the universe will continue ...
