Hello Everyone.
Hopefully you all are taking good care of yourself. So guys, it is not difficult for me to make a choice for this week's contest by @patjewell from the given options. Space and its attributes are always the subject of interest for me.
This romance started with "Gravity". Actually, I am not talking about the gravitational force but about the iconic science fiction movie every time. Obviously, Interstaller is a masterpiece , but my first love is always gravity. Okay, leave the movies and come to point the space.
Space |
|---|
The area around the earth where the gravitational force is affectless. Usually on earth it is about 100 km above sea level. Space is enigmatic and infinite without any strict boundaries. And it is complex to include all of its aspects in a limited piece of writing.
Space is a place where the rules and regulations applied on earth have vanished. For me, sometimes it is too difficult to understand the labyrinth of space. Because we humans have a very limited range of sight, understanding and thinking capabilities. But the only thing with which we can coup up to this trail is our passion.
Although the physical approach to space was made possible in the near past, studies about heavenly bodies were made from thousands of years. Primitive primates think that space bodies had an impact on their fate. They discovered some patterns of stars, some facts about the sun and then relate those facts to various things happening on earth, like season changing, path and direction determination. They also made many hypothetical superstesious stories related to space bodies.
A glance on Scientists efforts. |

The dogma of considering earth as the center of the universe was broken by Galileo Galilei. And after him, endless discoveries started. Edvin Hubble was the person who introduced cosmos to this world.
Yes, he is the person to which the name of the first ever telescope of the universe is dedicated. The first person who practically provided the first proof of space was Wernher Von Braun and Yuri Gagarin was the first ever homo to visit space. I also like to mention the first ever lady to visit space. Her name is Valentina Tereshkov.
Astronomy |
|---|
Astronomy is a separate branch of science to deal with space and all of its peculiarities. Astronomy has a vast range to study. We can conclude that astronomy is the study of everything except the land and its atmosphere. The space beyond the karman line is scientifically known as the Universe. The universe is a lot more than we ever thought. You can't even imagine this vastness of space. Our earth is even smaller than a sand grain size as compared to the size of the universe.
A Journey to space |
|---|
➡️Let's start a journey from earth.
➡️After 100 km from the earth surface at the karman line, we enter space.
➡️We are in the solar system and if we move out from here we will have to pass Mars, Jupiter, Saturn, Uranus, Neptune and dwarf planet Ploto.
➡️Oort cloud is the boundary line of the solar system. And now passing through it we are out of the solar system but still inside the milky way galaxy.
➡️Mily way is one of the large galaxies, and contains nearly 100 million stars. The center of the milky way galaxy is a black hole named Sagittarius A *.
This is the point around which our solar system revolves at a speed of 200km/sec. And the so-called boundary line of the Milky way is at 1.04 M light year from its center.Non of man made objects yet leaves a milky way.
➡️Out of the milky way we can now observe our neighboring and galaxy named Andromeda. This is going to merg in milk.Our local group of milk contains 100 more galaxies.
➡️According to recent research, the number of galaxies in the observable universe is approximately two trillion galaxies. Remember this is just an estimate.
➡️What is beyond this universe is still a mysterious secret, and Jamesweb is on the way to bring more facts on board.
At the end I invite
