Preface
The distant universe is not just an endless darkness, but is full of countless wonderful and mysterious mysteries of the universe. Scientists have discovered countless cosmic wonders in the starry sky, but most of them occur in very distant galaxies or planets, which are impossible to be seen by humans, and even the existence of some stars has been discovered by scientists only based on the data of subsequent calculations. However, in 1994, a cosmic spectacle appeared above the Earth, and humanity had the privilege of witnessing this shocking event up close - the impact of Comet Shoemaker-Levy 9 on Jupiter.
1. Jupiter
Jupiter is the largest planet in the solar system, known as the big brother of the solar system, it has a total of 67 moons, and its rotation speed is about 12.6 kilometers per hour in terms of rotation speed, which also causes its extremely obvious equatorial depression. And its orbital period is 11.9 years
It is an unformed star, a planet that was born to absorb stars, and can never become a real star, nor will it have a scarlet giant end up in stellar life.
Jupiter's reddish-orange appearance is due to its atmosphere, where light is absorbed and reflected by gases and dust, resulting in different colors and textures in Jupiter's diverse regions, including the Great Red Spot.
And most importantly, the existence of Jupiter not only "shelters the earth", but also really contributes to life on the earth, because its gravitational pull and atmosphere allow some asteroids and celestial bodies in the solar system to not fall to the earth or swallow the earth, and the sky only knows that astronomers can calculate the approximate time of the earth.
In addition, Jupiter also provides an indispensable thing for the origin of life on the earth - water, scientists believe that the earth may have been born at the beginning of an extremely arid planet, an asteroid with water in the universe that gave birth to life hit the earth and left water on the earth, so that there are all living things in the world today, and the asteroid may have many sources of water, one theory is that it is the source of water brought by the comet, and some people say that the water is brought by Jupiter.
II. Comet
Every year, as the night falls, countless meteors fly in the sky, which makes many people have great curiosity about meteors. But have you ever thought that a meteor is not just the fall of a star, but also the figure of countless comets wandering in the world?
These meteors are most commonly found in the night sky, and they are known by many other names: wishing stars, starlight sweeps, falling stars, meteor showers, and meteoroids, but whatever they are called, they are a strange kind of body incarnated by comets.
Comet is an extremely rare substance in a planetary system, it cannot be distributed like galaxies, nor can it appear as frequently as the sun, moon and stars, because comets are so rare that they cannot be confused with large and small planets, meteors or even asteroids, it has its own unique orbit, and also has its own unique shape, color and life
The essence of a comet is a very sensitive thing, once it is illuminated by the sun's light, it will gradually lose its essence, and after a long time, it will be like the soul has broken the thread, and it will disappear, but as long as it reaches a suitable place away from the sun, it will be like a soul possession and become a beautiful and charming cosmic wonder again.
Due to its very long distance from the sun, the place where the comet is located does not have the dazzling light of the sun, so in the dark night sky of the universe, it is like a shining elf, carrying too many legends and beauty.
And that tail is not only a big symbol of it, but also its talisman, it is precisely because of that long tail that the comet is not blindly colliding, but getting smaller and smaller, and finally disappearing, but often being reborn.
And its long tail has also become a big misunderstanding of it, too many people believe that it is the fall of the stars, whenever someone sees it, they will make a wish, in order to wish in their hearts, and some people, think that it is a tool of prophecy, whenever it appears, to see where it appears will be changed.
3. Comet Shoemaker-Levy 9 hits Jupiter
The so-called comet Shoemaker-Levy 9 was discovered on March 24, 1993, it is a comet captured in the solar system after decades of periodic orbit and the gravitational pull of Jupiter, and it is also a wonderful phenomenon that comets can cross the gravitational pull of Jupiter, and it produces wonderful phenomena.
July 16, 1994 was one of the most important days in human history, because on this day, we had the privilege of witnessing an astronomical spectacle of close impact. Comet Shoemaker-Levy 9, a comet that has been crushed by Jupiter's gravity, has brightened up the entire solar system, and humanity has had the privilege of witnessing a shocking impact up close.
Its collision with Jupiter may seem inconspicuous, but the power is not inconspicuous, but huge and amazing, and the energy released in this instant is enough to destroy everything in 19 square kilometers in an instant, and it releases a total of three trillion times of energy like this, even so, it is enough to easily flatten everything to the ground.
The impact also made the already cold and biting celestial body even more inaccessible, causing a 70% increase in weather and releasing more light than people could have imagined.
This impact not only added luster to Jupiter, but also gave humanity more scientific knowledge and provided some finishing touches for mankind to learn more about the mysteries of the universe.
The author thinks
As the big brother of the earth, Jupiter has repeatedly resisted potential dangers for the earth and provided an indispensable guarantee for the development of civilization on the earth.
