(B) the sea of stars in painting
As a visual art, painting can show the beauty and mystery of the sea of stars in a unique way. In the children's creative art class, they take the aerospace industry of the motherland as the prototype, express their space dreams with brushes, actively conceive and enthusiastically participate in aerospace theme painting activities. Children draw colorful dreams, and each painting expresses their real dreams.
Chinese painting, as a traditional painting form in China, is unique in depicting the stars and the sea. Painters create the depth and tranquility of the sea of stars through the shade of ink and the weight of brush strokes. For example, after contact with traditional Chinese painting, children feel the wonder of floating pen and ink wrapped around their fingertips. The faint ink lingers on the tip of the nose, and the ink is transpiration, which is as dreamlike as fog. In Chinese painting, the sea is no longer a simple accumulation of colors, but an expression of artistic conception.
Art students also show the romance of the sea of stars in their own way. They created a beautiful picture of the stars and the sea through seemingly simple operations such as coloring and sprinkling pigments. For example, in the course of "The Sea of Stars", art students first decorate the paper with pigments, then smudge it, sprinkle white pigments to create a lingering feeling like smoke, then decorate the mountains, and finally complete a picture of two people snuggling together, full of romantic atmosphere.
The sea of stars in painting is not only a beautiful visual presentation, but also an expression of artists' inner world. It inspires people's creativity, and allows people to appreciate the paintings, but also feel the endless charm and vision for the future brought by the stars and the sea.

(A) the contribution of basic research
As a Canadian-American physicist and theoretical cosmologist, James peebles has been regarded as one of the leading theoretical cosmologists in the world since 1970. His theory of cosmic evolution in 1960s laid a solid theoretical foundation for the rapid development of cosmology.
Peebles's theory covers BIGBANG's nuclear synthesis, cosmic microwave background radiation, cold dark matter theory, the theory of cosmic structure formation, the statistics of large-scale structure of the universe and other major research fields. The Big Bang model describes the moment when the universe was born about 14 billion years ago, when the universe was very hot and dense. Since then, the universe has been expanding and getting cold. After 400,000 years, the universe became transparent and light was able to travel through space. The original ancient radiation of the Big Bang, the cosmic microwave background, is still around us today. Using his theoretical tools and calculation methods, peebles successfully interpreted the traces of the early universe and discovered new physical processes.
His research results show us that the universe is like a cup of "coffee": 5% of it is known matter, composed of stars, planets and so on; The remaining 95% is unknown dark matter and dark energy. This discovery is a mystery and a challenge to modern physics. Peebles's theory of the evolution of the universe enriches the whole field of cosmology research, and enables human beings to have a deeper understanding of the composition and evolution history of the universe.
(B) Breakthroughs in the field of detection
The discovery of Michel Meyer and Didier Queloz started a revolution in astronomy. In 1995, they announced the first discovery of an exoplanet outside the solar system, which orbits a sun-like star in the Milky Way.
Their discovery satisfied mankind's long-standing curiosity about life in the universe. For a long time, people have always suspected that there are many other planets in the vast universe. Even Newton mentioned this conjecture in his works, but for a long time, there is no evidence. The discovery of Meyer and Queloz changed our understanding of the position of human beings and the earth in the universe.
Since they discovered the first planet outside the solar system in 1995, the Milky Way has discovered more than 4,000 exoplanets. The size, shape and orbital richness of these planets are unbelievable. Through the study of exoplanets, we can understand the evolution process of planets and draw a map of the whole universe for us, which is more strange and brighter than we thought.
In Meyer's and Queloz's time, it took not only in-depth research, but also some talents to discover exostars. They used the radial velocity method to determine the existence of planets around the star by observing the periodic blue shift and red shift of the star spectrum. The planet they found is still a very special planet, which is close to the star and has a large mass, which means that there are different forms of planets and stars orbiting in the universe. Since then, the discovery of exoplanets has indeed proved this point.

(A) the challenges and achievements of commercial aerospace
Taking Star Glory as an example, private commercial aerospace companies are facing many difficulties in building rockets. As a highly complex vehicle, the development process of rocket is full of challenges. From a technical point of view, a qualified rocket needs a shell with high strength, high and low temperature resistance, low density and easy processing, as well as a high-performance propulsion system and an accurate control system. This requires a lot of R&D efforts in material selection and processing, engine development and overall system integration.
During the development of interstellar glory, the hyperbolic-1 commercial launch vehicle suffered a launch failure. For example, the hyperbolic remote five rocket launched on August 3, although the solid motor, liquid attitude and orbit control power, navigation guidance and control work normally, the separation between stages and the separation of stars and arrows are also normal, but the flight test failed to achieve the expected purpose due to the failure of fairing separation. This incident highlights the quality control of thousands of parts during the development and launch of rockets. How to ensure the stable operation of each component and build a stable supply chain suitable for their own enterprises has become a difficult problem that private commercial aerospace companies must face.
However, interstellar glory has also made many achievements. As a star enterprise in the domestic private commercial aerospace field, StarCraft Glory successfully developed the Hyperbolic No.1 four-stage small solid launch vehicle, and achieved the first successful launch, becoming the first private rocket enterprise in China and the third in the world to launch the rocket into orbit. In addition, StarCraft Glory continues to explore and actively carry out technological innovation in the R&D and design of the reusable liquid launch vehicle Hyperbolic II. For example, it has reusable, variable thrust liquid rocket engine Focus No.1, 100-ton reusable, variable thrust liquid oxygen methane engine Focus No.2 and other products, which have accumulated key technologies for the development of commercial aerospace.
(2) Future prospects of commercial aerospace
China's commercial aerospace industry has a bright future, and it is expected that there will be companies comparable to SpaceX in the future. At present, China's commercial aerospace industry is booming with the support of policies, and many private aerospace enterprises such as Blue Arrow Aerospace, Star Glory, Tianbing Science and Technology, Zhongke Aerospace, Xinghe Power, and Oriental Space are on the rise. These enterprises have continuously made new breakthroughs in rocket development and satellite launch, which has injected a strong impetus into the development of China's commercial space flight.
Taking Blue Arrow Aerospace as an example, it mainly focuses on liquid oxygen methane rockets, and has built Huzhou engine manufacturing base, Jiaxing Quanjian assembly base and Jiuquan liquid oxygen methane exclusive launch base. In July 2023, the Suzaku-2 rocket was successfully launched, becoming the world's first liquid oxygen methane rocket successfully put into orbit. On December 9, 2023, Suzaku II Remote 3 Rocket was successfully launched again, which was the first official commercial launch of liquid oxygen methane rocket in the world. Blue Arrow also announced a reusable liquid oxygen methane launch vehicle, Suzaku III, which is expected to fly for the first time in 2025, aiming at Falcon 9.
With the continuous progress of technology and the gradual maturity of the market, China commercial aerospace enterprises will make new breakthroughs in recoverable rocket technology, satellite Internet construction and commercial launch site operation. In the future, China commercial aerospace enterprises are expected to make greater achievements in reducing launch costs, improving launch efficiency and expanding application scenarios, so as to provide stronger support for the exploration of the sea of stars. At the same time, China's commercial aerospace enterprises will also show stronger competitiveness in the international market and become an important force in the global commercial aerospace field.

(1) A trip to idolize
Li Yige, a senior student of Jinan University, as a space enthusiast, often looks up at the stars and shoots little stars. He waited for more than half a month to film the transit of the Chinese space station. This shooting is not only the pursuit of the stars and the sea, but also the persistence of dreams. Together with the reporter of Life Gang, he welcomed the appearance of China Space Station in expectation. At that moment, his heart was full of excitement and pride. His trip to idolize represents the yearning of countless young people for the sea of stars and inspires more people to explore the mysteries of the universe.
Ren Yufeng, a first-year Ph.D. student at Xi 'an Jiaotong University School of Aeronautics and Astronautics, is also an aerospace enthusiast and photographer. He made full preparations in advance to film the Chinese Space Station flying over science and technology of west china Innovation Harbor. After checking the time, angle, brightness and other information of the space station flying over in the "Astronomical Communication" applet, he made an appointment with his classmates, carried the camera to the top of the dormitory building in the early morning, set the shooting interval, and waited for the space station to fly over. Despite the cold weather, he felt extremely happy and excited when he saw the space station crossing the sky like a very bright star. His shooting experience not only showed his love for the aerospace industry, but also let more people see the beauty of the sea of stars.
Students from Tsinghua University also joined the trip to idolize. They used different equipment to capture the picture of the Chinese space station passing the moon. Although the actual passing of the moon was only 0.54 seconds, they set up the equipment and waited for more than an hour for this moment of less than one second. Their shooting process can not be separated from the cooperation of many people in the team and the support of the community. At the same time, they also showed their love for China space flight and their yearning for the stars and the sea.
(B) the sea of stars in music
Liu Yu's song "Controlling Dreams as a Boat" is warm and powerful, and the song reviews the picture of the development of China's space industry in the past 30 years. From the first experimental spacecraft to the 14 manned spacecraft in China, countless astronauts have gone wave after wave for their dreams. The lyrics and melodies are progressive step by step, which vividly depicts the appearance of astronauts bravely marching forward and not afraid of difficulties. "Nobody's business, weightlessness space you walk freely. Aurora arrival, stop at the hatch where you look far away. Don't ask how to freeze it forever. Holding a dream is immortal. " This lyric shows the romance and persistence of astronauts.
Cool Dog Music and China Aerospace released the song "Star on Earth", which was performed by "Cool Dog Aerospace Creative Ambassador" Wen Yixin. This song vividly conveys China astronauts' firm belief in loving the motherland and winning glory for the country, their enterprising consciousness of independence and daring to surpass, their character and style of overcoming difficulties and daring to climb, and their lofty qualities of being indifferent to fame and fortune and silently contributing. At the same time, it also inspires every listener. As long as we are firm in our beliefs and dreams, we will eventually become "the brightest star in the universe".
The Central Conservatory of Music Chorus performed the concert "Spirit of China", and one of the tracks "Desert Rose" praised the aerospace spirit. Under the command of Chen Bing, a young conductor, the choir expressed its praise for the astronauts' hard work, selfless dedication and great achievements with a magnificent and emotional interpretation.
(C) the beauty of the astronauts' lens
From a scientific point of view, the photos of the stars and the sea taken by astronauts record valuable information such as the distribution, trajectory and nebula shape of stars, which provides valuable information for astronomers to study the origin of the universe, the evolution of galaxies and the distribution of dark matter. For example, through the observation of supernova remnants, gamma-ray bursts and other phenomena, scientists can gain insight into the physical processes in the extreme environment of the universe and even explore the fate of the universe. In addition, shooting the night view of the earth helps to monitor global issues such as urbanization, climate change and biological activities, and provides strong support for earth science research and policy formulation.
From a humanistic point of view, the photos of the stars and the sea under the lens of astronauts let us intuitively feel the grandeur and mystery of the universe, which leads us to ponder over the ultimate problems such as life, existence and the universe. Those seemingly quiet and fixed stars on the earth show the beauty of dynamic rhythm under the lens of astronauts. The stars seem to be transformed into bright dancers, dancing on the dark sky and interweaving into flowing paintings. This kind of beauty lies not only in its visual impact, but also in its far-reaching touch and enlightenment to the human spiritual world. It inspires us to pursue scientific truth, yearn for harmony and symbiosis, and recognize the community of human destiny.
The night view of the earth under the lens of astronauts is breathtaking. Viewed from space, our blue home shines in the dark, and the outline of the land is like an emerald island embedded in the deep sea under the outline of light. The ocean part is a dark abyss, and the occasional flashing ship lights and city lights are like faint fluorescence from underwater creatures, suggesting the pulse of life. From this perspective, the earth not only shows its warmth as the cradle of life, but also reveals its loneliness and smallness in the cosmic scale, which causes people to deeply respect and care for their homes.

(A) the attraction of the mysteries of the universe
Since ancient times, human beings have never stopped exploring the mysteries of the universe. In ancient Greece, philosophers began to think about the nature of the universe. Pythagoras thinks that numbers are the cornerstone of the universe, and everything can be explained by numbers. He emphasizes the relationship between music and mathematics, and thinks that both music and mathematics are an expression and revelation of the essence of the universe. Thales, on the other hand, put forward the view that "everything originated from water". He believed that water was the origin of everything and formed the original substance of the world. He also successfully predicted an eclipse in the field of astronomy, demonstrating his extraordinary logical reasoning ability.
With the passage of time, mankind's exploration of the mysteries of the universe continues to deepen. The development of modern science and technology provides a powerful tool for us to uncover the mystery of the universe. As one of the world's leading theoretical cosmologists, James peebles's theory of cosmic evolution covers BIGBANG's nuclear synthesis, cosmic microwave background radiation, cold dark matter theory and other major research fields, which enables human beings to have a deeper understanding of the composition and evolution history of the universe. Michel Meyer and Didier Queloz discovered the first exoplanet outside the solar system, which started a revolution in astronomy and gave us a new understanding of the existence of planets in the universe.
