Department of Astronomy and Department of Astronomy
The Department of Astronomical Affairs was the name of an ancient official office. Its function was to observe astronomy and calculate the calendar. Its name changed in different dynasties. For example, before the Sui Dynasty, it was called the Taishi Ling, Taishi Bureau, or Taishi Jian. In the Tang Dynasty, its name changed many times. In the Song and Yuan Dynasties, it was called the Department of Astronomical Affairs, the Department of Tiantai, or the Astronomical Academy. In the Ming and Qing Dynasties, it was called the Imperial Astronomical Administration. The Director of Celestials was the official in charge of the Heavenly Division. The Heaven Inspectorate had different meanings in different situations. In the settings related to the prison, the Nether Demons in the prison formed the Heaven Supervision Bureau to fight against the Ten Kings of Hell. It was formed by three directors, and under the directors were eight kings and sixty-four generals. It was protected by countless Nether Demons and was the most powerful force in the prison. It was responsible for the security of the prison, and there was also a security team called the Breaking Formation Camp formed by 500 Nether Demons. In the setting of the Yue Country in the Alien Continent, the Heaven Inspectorate was one of the five supreme organizations in the Yue Country. It was responsible for managing astronomical and geographical affairs, investigating strange and secret matters in the Yue Country, and its headquarters was set up in Jiang City.

The rudiments of astronomy
Based on context alone Astronomy was a science that studied celestial bodies and the universe. The following were some basic knowledge of astronomy: ** 1. Celestial Body Type ** 1. ** Stars ** - A star was a spherical glowing plasma celestial body condensed by gravity. The sun was the closest star to Earth. The star's interior produced energy through nuclear fusion reactions and radiated light and heat. For example, the fusion of hydrogen into helium released a huge amount of energy, maintaining the light and heat of the star. - Stars had different sizes, masses, and luminosity. Massive stars usually have high luminosity and short lifespans, while low-mass stars have low luminosity and long lifespans. 2. ** Planet ** - Planets were celestial bodies that orbited a star in an oval orbit, and they were so massive that they could rely on their own gravity to make their shape similar to a sphere. They could also clear other celestial bodies near their orbit. In the solar system, there were eight planets. They were Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from the sun. - Planets could be divided into terrestrial planets (like Earth, which had a solid surface) and wood-like planets (like Jupiter, which was mainly made of gas). 3. ** Satellite * - A satellite was a celestial body that orbited a planet. Earth's satellite was the moon, which had an important influence on Earth's tidal phenomena. The size, shape, and composition of the satellites varied. Some satellites had a large number of craters on the surface, while others might have special geological activities. 4. ** Asteroid and comet ** - Asteroid was a celestial body in the solar system that was similar to planets orbiting the sun, but much smaller in size and mass than planets. They were mainly distributed in the asteroid belt between Mars and Jupiter. - Comets were small celestial bodies made of ice and dust. When they approached the sun, the ice would sublimate to form a comet's coma and tail. The comet's orbit was usually a very long oval. ** II. Observation Tools and Methods ** 1. ** Binoculars ** - An optical telescope was the most common type of telescope. It observed celestial bodies by collecting and focusing light. It could be divided into refraction telescope and reflection telescope. A refraction telescope uses a lens to reflect light, while a reflection telescope uses a mirror to reflect light. - Radio telescopes observed celestial bodies by receiving radio waves emitted by them. It was of great significance for the study of celestial bodies that were difficult to detect by optical observation, such as pulsar. 2. ** Astronomical Observation Location ** - The ideal astronomical observation site should be far away from urban light pollution, and the sky should be clear and cloudless. For example, some high-altitude, dry areas, such as the Atacama Desert in chile, were ideal locations for many large astronomical telescopes. ** 3. The structure of the universe ** 1. ** Solar System ** - The solar system was made up of the sun, planets, satellites, asteroids, comets, and other celestial bodies. The diameter of the solar system was about one light year, and the mass of the sun accounted for the vast majority of the total mass of the solar system. 2. ** Milky Way ** - The Milky Way was a spiral galaxy that contained hundreds of billions of stars. The solar system was located on a spiral arm of the Milky Way, and there might be a supermassive black hole at the center of the Milky Way. The diameter of the Milky Way was about 100,000 light years. 3. ** Galaxy clusters and superclusters ** - Multiple galaxies gathered together to form a galaxy cluster, and multiple galaxy clusters formed a supercluster. There were a large number of galaxy clusters and superclusters in the universe, and their distribution and structure were important for studying the evolution of the universe.
The meaning of astronomy
Astronomy was important in many ways: ** I. The significance of scientific cognition ** 1. ** Advancing understanding of the structure and evolution of the universe ** - Astronomy studied the distribution, position, laws of motion, chemical composition, physical state, and the structure and evolution of celestial bodies and the universe. For example, through the study of celestial bodies at different levels (such as celestial bodies in the solar system, celestial bodies in the Milky Way, and extragalactic galaxies), the overall framework of the universe could be constructed and the development process of the universe from its birth to the present could be understood. - The proposal of the Heliocentric Model from the 16th to the 18th century challenged the traditional view of the universe and helped to establish a more accurate understanding of the solar system. This was an example of astronomy deepening human understanding of the structure of the universe. 2. ** Exploring unknown matter and energy ** - Modern astronomical research found that the energy of conventional matter that humans could perceive only accounted for 4% of the entire universe's energy, and the other 96% was dark matter and dark energy. This prompted scientists to explore the nature of these unknown matter and energy, thus promoting the development of physics and other disciplines. - For example, the study of galaxies and the universe brought about the nature of dark matter and dark energy, the "two new dark clouds" of modern physics, which inspired scientists to further explore the mysteries of the universe. 3. ** Testing basic physics principles ** - The extreme astrophysical conditions in celestial bodies provided a natural laboratory for testing basic physical principles, including the general theory of relativity. For example, through the study of gravitational waves, black holes, and other celestial phenomena, basic physics theories could be strictly tested. 4. ** Promotion of cross-disciplinary development ** - The combination of astronomy and physics gave birth to astrophysics, which became the mainstream of contemporary astronomy and provided a place for the testing of physical theories. - Astrochemistry and astrobiology used chemistry and biology to study the chemical processes in the interstellar medium and extraterrestrial life. The development of these cross-disciplines enriched the content of scientific research. ** 2. Meaning to human society ** 1. ** Reflects the country's scientific and technological strength ** - The level of astronomy innovation had become a comprehensive embodiment and an important symbol of the scientific and technological strength of countries, especially big countries. For example, China's "Heavenly Eye" and "Wukong" and other major achievements in the field of astronomy reflected China's strength in astronomy research. 2. ** The role in education and popular science ** - It played an important role in improving the scientific quality of the people. It helped to cultivate students 'innovative spirit, scientific thinking methods, and tenacious good quality. 3. ** Support for national strategic needs ** - Advanced astronomical technology to explore the formation and evolution of the universe was widely used in navigation, positioning, aerospace, deep space exploration and other fields, playing an important role in national economic construction and national security. For example, the detection of weak signals under high noise in modern astronomical observations, precise space navigation and positioning technologies met national strategic needs such as national security, manned space flight, and the "Chang'e" lunar exploration project.

Ancient Roman astronomy
Astronomy in ancient Rome was not only an important part of its culture, but it also left a strong mark in the history of ancient science. From daily astrological observations to complex calendar development, ancient Roman astronomy reflected the depth and persistence of human exploration of the universe. ###Main Achievement of Ancient Roman Astronomy - ** Ptolemy System **: Ptolemy was one of the most famous astronomy experts in ancient Rome. He proposed the geocentric theory, which was the theory that all celestial bodies moved around the Earth. This theory dominated the scientific community at that time and had a profound impact on later generations of astronomy. - Calendar Development: Ancient Rome also had significant achievements in the development of the calendar. Caesar implemented the Julian calendar, which was based on the ancient Egyptian solar calendar. The year was set at 365 days, and one day was added every four years as a leap year. This calendar was later revised into the Gregorian calendar in the 16th century, becoming the Gregorian calendar in use in the world today. ###Ancient Roman Astronomy - Military: Astronomical observation played an important role in the military operations of ancient Rome. Astronomical soldiers observed the stars and predicted the weather and seasonal changes, providing important reference for military operations. - Agriculture: Ancient Rome used astronomical knowledge to guide agricultural production, such as observing the position of the sun and stars to determine the timing of sowing and harvesting. Astronomy in ancient Rome was not only an important part of its culture, but also an important milestone in human understanding of the universe.
