Space

 The space station     is an artificial construction dedicated to activities in low orbit around the Earth for various purposes with sufficient internal space and qualified to host humans and save life designed to remain in low Earth orbit for a relatively long time, space stations have the potential to integrate with spacecraft from Earth in general, the International Space Station is the only operational and currently inhabited station and there have been many previous stations such as the Russian Sal station as well as the Alma station, Skylab and Mir station that fell and burned in the cover on March 23, 2001. And a station. Chinese space such as Tiangong-1 station that fell and crashed on April 2, 2018 Space stations are used to study long-term effects on the human body, also considered a platform for lengthy scientific studies, and all space stations are designed to be rotated by multiple crews, of each crew from which one person is left for weeks or months, and rar...

   Space flights: Space flights began in response to human curiosity to probe the depths of the Earth, the moon, planets, the sun and other stars and galaxies. Manned and unmanned vehicles roam beyond Earth's borders, collecting valuable information about the universe. Man visited the moon and lived in space stations for long periods. Space exploration thus helped us to see what the real relationship between Earth and the rest of the universe was. Space exploration answers how the sun, planets and stars are formed, and whether there is life elsewhere in the universe. Unmanned vehicles, called space sensors, have increased our knowledge of outer space, planets and stars. In 1959, a space probe passed near the moon, and another hit it. In 1962, an American sensor flew near Venus. In 1974 and 1976, the United States of America launched Two German space sensors into the orbit of mercury, which is close to the sun. In 1976, two American sensors landed on Mars. These sensors studied...

Universe The universe is what exists in the dome of the sky, of which celestial bodies are dark like planets, the earth on which we live one of these planets, and of the celestial bodies what is illuminating and moving like stars, as our sun, which provides us with light and heat, is one of them, and the scientific concept of the universe is that it is the vast space that contains stars, galaxies, planets, meteorites and comets, as they all belong to the so-called galaxies and there are a large number of them and these galaxies are different forms, some of which are It's oval, and some of it's my penis, and the most famous of these galaxies is the Trail Galaxy  the milky planet to which our planet belongs. The sky we see is not a physical medium, but it is gases in constant proportions spreading in space and what blue we see is only the only color of the spectrum that remains resulting from the degradation of sunlight, and all the celestial bodies in space are members of our pl...

  Elements of the solar system: The solar system consists of: the star of the sun, in addition to all the celestial bodies orbiting it by the force of gravity, these bodies include: planets, dwarf planets, moons, asteroids, comets and meteorites, all the objects of the solar system are located in the Milky Way galaxy, and the following is an explanation of these clusters.

  Com ponents of solar system planets   The planets of the solar system are divided into two main parts, each differing in the nature of its constituent materials, and these two sections are: terrestrial planets, or what are known as inland planets, which include: Planet Earth, Mercury, Venus and Mars, where all These planets are mainly rocks, different minerals, exoplanets, or giant gas planets, which include Jupiter, Saturn, Neptune and  Oran, with the planets of this group consisting mostly of gaseous elements, as well as water,  Here's an intense look at the nature of the components of each of these planets

What is Space:  Space is defined as the space between celestial bodies , called outer space to distinguish it from the air space a round the glob ,and space can also be defined from a physical perspective as a three- dimensional,  unlimited space in which objects take relative position and directions.
