The world of outer space

An absolute vacuum exists between the celestial bodies, consisting of helium, hydrogen, and electromagnetic radiation. Outer space contains galaxies, stars, planets and moons, as well as the sun and the moon, and occupies a larger space than the universe. Astronaut Charles Edouard Guillaume, the first spacecraft in 1961, and then expanded flights until all the planets of the solar system and the moon arrived, and the outer space begins at a height of 100 km above the level Sea, which is called the line of Carmen, and the purpose of recording aerial measurements and treaties in space. The space was first discovered by remote observation with the naked eye, then the telescope was used, and then the balloons were used, until the Germans came and fired the first missile 80 kilometers away in 1942 and the Sputnik then launched. The space of the Soviet Gagarin to circulate around the Earth, and in 2012 the first vehicle was launched up to the interstellar space, leaving the solar system. But manned flights were confined to Earth and moon space, unmanned flights to the solar system, the rest of outer space that humans could not reach, and only the telescope. NASA was the agency responsible for astronauts and spacecraft. Outer space zones Terrestrial space: is an area near the Earth, where it contains the upper area of ​​the atmosphere, the magnetosphere. Space of the moon: the area confined between the earth's atmosphere, the orbit of the moon, and also the points of the Ingrid. Interplanetary space: the reality between the sun and the solar system, where planets are controlled by an extension of the atmosphere of the sun to the end of the long tail outside the planets, including Mercury, Venus, Mars, Earth, Jupiter, Saturn, Uranus and Pluto, , Dust, small meteorites, and plasma. Space: This is a physical space in the galaxy, which is not occupied by stars or planetary systems. This space is made up of atoms of hydrogen and helium. Intergalactic Space: The space between galaxies, characterized by high temperatures, consists of hydrogen ions. The effect of outer space on the human body The absence of gravity in outer space has a negative impact on the functions of human life, and from these damage: causes the shedding of human muscles, and the fragility of the bones. An explosion in the lungs, due to differing pressure on the chest, leads to an explosion of the sinuses, the eardrum, in addition to leakage of blood in the tissues. Swelling, in order to decrease the amount of oxygen entering the brain, and the boiling of body fluids, because of low pressure, then coma and death. Note: Tailor-made suits are designed for the astronauts, which are equipped to protect the body from swelling, relieve external pressure, and provide oxygen for breathing.
