Space exploration from zero
Outer space is still, according to us, one of the things that are filled with great secrets. Whenever we discover one of them, we find more secrets and our questions increase. That is why man excelled in pursuit of that puzzle, until the last of which was the James Webb space telescope of an American origin.
james webb space telescope In order to answer this question, it is necessary to go through the matter from its very beginning, since the thought of man in outer space
What is outer space?
Since ancient civilizations, man has not stopped asking a question, but rather many questions about what is going on around him or in himself, and here in the article we are talking about outer space, and let me give you a quote from its definition
"Outer space is the void that exists between celestial bodies, including the planet Earth. It is not completely empty, but is made up of a relative void made up of a low density of particles, mostly hydrogen and helium plasma, as well as electromagnetic radiation, magnetic fields, and neutrons."
Where did the definition of outer space come from?
As I told you earlier, man began to seek an answer to the question of what is going on around us, who I am and what my identity is, and here he began to research and think since ancient civilizations, and many traces appeared that indicate man’s attempt to explore space, as well as religions also dealt with the subject, which is in Most of them are based on an answer to these questions, and the Noble Qur’an is considered the most documented book of cosmic events or information about outer space, which is now being debated. for the International Space Agency.
What are the tools used in space exploration?
To discover space, there was one obstacle, which is that the human eye does not perceive things in their natural size. Telescope and its many types
What is a telescope? And its types?
A telescope is a machine that collects light in one point to facilitate seeing distant planets and stars clearly, creating close-up images of celestial bodies. Telescopes are usually either reflecting or refracting. It is used to see distant objects.
Reflecting telescope
It uses a large concave mirror shaped into a parabola. With the main mirror, another concave mirror is used, facing the main mirror, so that the rays are reflected and focused in a focus behind the main mirror. In the center of the main mirror there is a small hole through which the rays of the secondary mirror pass so that the image can be seen at the focus.
refractor telescope
Refractions are manually controlled automatically; The sizes of the lenses that refract light range from 50-150 millimeters.
However, things took a turn until we got to the James webb space telescope
The James Webb Space Telescope, or JWST, is a space observatory developed directly by NASA, the European Space Agency, and the Canadian Space Agency. It is planned to succeed the Hubble Space Telescope as part of NASA's Flagship astrophysics mission.
What does the James Webb telescope do?
It detects the sky in the infrared spectrum - the light that lies at distances that the naked eye cannot perceive. This will enable the Webb telescope to probe the depths of the universe to a greater extent than the previous Hubble telescope could. And space showed us the first color image so that we could see how the planet, stars, and solid figures that we know nothing about appear to us, making it easier to identify the constituent elements of planets and clearer maps about the materials that make up them.
Where is James Webb telescope now?
Where is the James Webb Telescope now? The Webb telescope is pretty far away – 1 million miles from Earth to be exact. It launched in December 2021 from French Guiana.
