This paper provides an introduction to astronomy, covering its basic concepts, a brief history, and its various fields of activity. It discusses the importance of astronomy in understanding astronomical phenomena and its contributions to the continuous construction of scientific knowledge. The paper explores the technological tools used in astronomy, such as telescopes, programming languages, engineering, and space stations. It is characterized as both "exploratory" and "bibliographic," aiming to familiarize readers with the main concepts of astronomy through logical, organized, and structured content. The text is written in a didactic manner to help readers interested in astronomy understand the subject clearly and comprehensively. The history of astronomy is traced back to ancient civilizations, highlighting early observations and the development of calendars. The paper also delves into the contributions of notable figures like Aryabhata, al-Khojandi, and Copernicus, who advanced the field with their theories and observations. Modern astronomy is discussed, including the development of radio astronomy, infrared astronomy, optical astronomy, ultraviolet astronomy, X-ray astronomy, and gamma-ray astronomy. The paper also covers non-electromagnetic fields, such as neutrino astronomy and the detection of gravitational waves. The paper further explores specific subfields of astronomy, including solar astronomy, planetary science, stellar astronomy, galactic astronomy, extragalactic astronomy, cosmology, and theoretical astronomy. It emphasizes the interdisciplinary nature of astronomy, highlighting its links with fields like archaeoastronomy, astrobiology, and astrophysics. In conclusion, the paper aims to provide a comprehensive and accessible introduction to astronomy, encouraging readers to explore the vast and fascinating universe.This paper provides an introduction to astronomy, covering its basic concepts, a brief history, and its various fields of activity.
