Probably many of us in childhood saw the starry sky, especially in the warm August night.The mysterious black space has always been interested in people.We, like our ancestors, we are trying to understand what this unknown world is fraught?This and many other questions that children often ask their parents, sometimes it is difficult to give an answer.And what is the space for us adults?What do we know about him?
order and harmony
From dictionaries can be found, which is translated from the Greek word "cosmos" means "harmony", "order".Greek philosophers, this word refers to all the universe, seeing it as an ordered system, which is different, in contrast to the confusion and chaos, harmony.There was a time when this concept researchers included the whole nature of the Earth, all that was happening to her.Also included are the heavenly bodies, planets, stars, galaxies.Known titanic work, called "Cosmos".Author Alexander von Humboldt concluded in his five volumes of all known at the time about the nature of the information.That is, there was all about space.
universe
What is space in our time?The concept is endowed with, perhaps, the true meaning and its meaning "the universe."After all, the space includes stars, planets, asteroids, comets, a variety of cosmic light, as well as all the interstellar space.These components are interconnected.They exist, known only to them obeying the laws, and these laws are always people trying to solve.Trying to understand what space probably will not stop ever.This mystery excites the minds of people.
near and far space
Conditionally entire space of the universe is divided into the far and near space (near-Earth space).The area, which is located in the vicinity of our planet has been studied extensively by satellite.These are special vehicles that allow a person to take an active part in space exploration.A large number of satellites exploring near-Earth space by yourself.
Deep space for humans is not available.But let's hope only temporarily.This area someday also be a busy man.
Milky Way
Scientists believe that the cosmos is made up of a large number of galaxies.The word "galaxy" comes from the Greek "galaktikos" means "milk".That's why our name, which is the Earth, the solar system and all the visible stars - "The Milky Way".
Each galaxy - its specific structure, and they, in turn, are made up of different systems of stars.Our Solar System - is the main star of the Sun and the planets revolving around it.Here there is also a large number of different cosmic bodies and cosmic dust.The magnetic field makes it possible to keep it all together and revolve around the sun.Each planet has its own path, or orbit.Many of them have their natural satellites orbiting them.
Thinking about what a space, we always come to the conclusion that he is so enigmatic and mysterious that you can talk about it endlessly.Each of the celestial bodies is unique and, in turn, could be the subject for discussion.And people will explore all this boundless space, while he exists and is a small part of it.
