Features: When we look up at the sky, we see scattered stars. The boundless sky holds various kinds of stars—stars, meteors, comets. They orbit in their respective paths, forming mysterious and magnificent galactic systems, much like the solar system and the Milky Way. These numerous galaxies and diverse celestial bodies make up the universe we live in. Initially, ancient people believed in the theory of a "round sky and square earth." As society progressed, the geocentric theory, which placed Earth at the center of the universe, dominated astronomy for nearly a thousand years. In the 15th century, the Polish astronomer Nicolaus Copernicus proposed the "heliocentric theory" in his book, causing a sensation worldwide and panic among the Church. It wasn't until the advancement of technology that humans finally landed on the moon in 1969, proving Copernicus's theory. Today, astronomy has advanced to the point where observations of the universe have expanded from the ground to space, with numerous space probes launched. Humanity's understanding of the universe has been a long and arduous journey. This series of books, written by experts in China, systematically presents the latest technology and knowledge in various fields such as astronomy, aerospace, military, transportation, oceanography, geographical environments, and biological engineering, all of which are closely related to our lives. We hope this series can help readers understand the ever-changing world and integrate into the society of the E. Editors October 2005
