Has man been interested in space and stars since ancient times and continued to do so? And what are the reasons for that? Man in the ancient era attracted his attention to many things, and he was very interested in them, especially astronomy, and everything related to space and planets, so through our topic today we will learn regarding the fact that man is interested in space and planets and the reason for that.
Since ancient times, people have been interested in space and stars
At the present time, we live in a world full of recent discoveries, and continuous developments, especially in technology, and among the most prominent things that have been discovered regarding many things are space and stars that astronomers have never stopped doing a lot of research on everything related to them.
Since ancient times, man has been interested in space and the stars and has continued to do so until the present time due to his ability to discover many important matters due to their extreme importance in understanding and knowing the cosmic truth.
Because it helps the human to learn, and know the facts faster, and astronomers and astronomers were able to expand on this a lot until they were able to discover galaxies and planets.
A lot of studies have always been conducted to identify the planets, the entire space, and the objects in space, in order to see if they pose a danger to the planet. In the past, humans used the naked eye, and some primitive devices, but in our dreaming era, telescopes and space observation devices were created. sophisticated.

What does space contain?
There are many elements in space, such as gases in two forms, nebulae, which are cold clouds composed of neutral hydrogen molecules in addition to ionized hydrogen, and it is near the newly formed stars, and it occurs as a result of ultraviolet radiation from the stars.
There is also dust in space, which consists of a lot of various things such as: iron, oxygen, aluminum, silicon, and carbon, and these elements begin to get high when an explosion occurs in metals.
There are many components present in space, such as: cosmic radiation, light, radiation as a result of the explosion, winds of charged particles, magnetic and electric fields, and neutrons that are emitted from nuclear reactions in stars.
Reasons for human interest in space and stars
The reason for human interest in space and the stars is that they help to know everything related to the universe, and to know everything that surrounds space of cosmic materials and stars, and with time, many devices have been discovered that allow the possibility of determining the state of climate and weather, through satellites available in space.

Important information regarding space
There are many important information related to space that many people do not know. Space is the space between celestial bodies, and it is known as outer space.
It is regarding 100 km away from Earth, and black and blue color spreads in it, due to the absence of external light of oxygen, and there are some important information related to space, which we mention as follows:
|
There is no gravity on space. |
|
Space lacks air that helps all living things breathe. |
|
A person can never go into space without a suit because he would be light. |
|
The footprints of humans may remain in space for many years. |
|
Outer space does not contain any sounds. |
|
Today on Earth is different from Mars. |
|
Space contains a huge number of stars. |
Space science includes many general things that man has continued to search and see since ancient times in order to be able to access them, as it contains many important materials.
