資本結構描述：：1. Atmosphere Atmosphere is the name given to the mass of gases that surround a planet. It is composed of nitrogen, oxygen, carbon dioxide and water vapor, as well as other minor constituents such as argon and methane. The atmosphere is important because it acts as a shield against ultraviolet radiation from the Sun and also helps to moderate the temperature on the surface. The atmospheric pressure of the Earth affects global weather and air circulation patterns, and plays an important role in the global climate system. 2. Space Space is the expanse that exists between celestial bodies, including the Earth and other planets, stars, galaxies and the entire universe. It is believed to be an infinite void, but is filled with interstellar gas and dust. Space is often referred to as the vacuum of space since there is no air or other matter located there. Space is believed to have been created during the Big Bang, which is thought to have occurred approximately 13.8 billion years ago. The expansion of space is thought to be constant, and its properties can be studied through various types of telescopes and other instruments. 3. Void A void is an empty space in the universe, a region that appears to have very little matter or energy. This type of space can be found between galaxies, in vast regions of intergalactic space, or even inside certain galaxies. It is theorized that the voids may be the result of the uneven distribution of matter throughout the universe, or may be consequences of dark matter or dark energy. Some voids are believed to be home to dark galaxies and other dark matter concentrations. 4. Galaxy A galaxy is a massive collection of stellar objects, dust, and gas held together by gravity. The objects in galaxies, such as stars, planets, and gas clouds, move under the influence of their mutual gravitational attraction, and most galaxies contain hundreds of billions of stars. Three of the most common types of galaxies are spiral galaxies, elliptical galaxies, and irregular galaxies. The Milky Way, which contains the Solar System, is an example of a spiral galaxy. 5. Cosmos 1. Aerospace： Aerospace is a type of space that specifically deals with the Earth's atmosphere and near-space environment as well as working towards the exploration of space. It is involved in research, design, and engineering related to aircraft, spacecraft, satellites, rocket propulsion systems, and more. 2. Astronomy: Astronomy is the scientific study of celestial objects and phenomena that originate outside of the Earth's atmosphere. It's a way to study the universe and its history, from the birth of stars and galaxies to the formation of planetary systems and the evolution of life. 3. Cosmology: Cosmology is the study of the origin, structure, and space-time of the universe as a whole. It includes topics such as the Big Bang theory and the nature of dark matter and dark energy. 4. Extraterrestrial Life: The scientific study of life existing on other planets, moons, and other celestial bodies outside of Earth's atmosphere is known as extraterrestrial life. This study holds many implications in the fields of planetary science, biology, and astrobiology. 5. Spacetime: Spacetime is a concept that combines space and time in a single framework to describe the structure of the universe. It was first proposed by Albert Einstein in his theory of general relativity in 1915 and states that space and time are linked together, forming a four-dimensional continuum. 6. Space Exploration: Space exploration is the study of objects and phenomena in outer space. It includes missions to explore the Moon and Mars and the construction of the International Space Station. It also includes technology development, such as the creation of new telescopes to study the universe from afar. 7. Celestial Mechanics: Celestial mechanics is the application of Newtonian mechanics and mathematics to the motion of planets, moons, asteroids, and comets. It's useful for predicting the location of objects in space and the effects of the gravitational force on their motion. 8. Outer Space Law: Outer space law is the legal framework regulating activities in space, such as the exploration and use of space, including spacecraft and satellites. It covers issues such as property rights, space debris, and liability for damages caused by space objects. 9. Astrobiology: Astrobiology is the study of the origin and evolution of life in the universe. It seeks to answer questions about how life came to exist, how it evolves and adapts, and the possibility of life beyond Earth.
