Astronomija, or astronomy, is the scientific study of celestial objects, space, and the universe as a whole. It involves observing and understanding phenomena beyond Earth’s atmosphere, including stars, planets, comets, galaxies, and the cosmic background radiation that informs us about the universe’s beginnings and evolution. Astronomy combines physics, mathematics, and chemistry to analyze the behavior and properties of these celestial bodies and their interactions. It is one of the oldest sciences, rooted in the ancient observations of the night sky, and has evolved into a modern discipline that employs complex instruments like telescopes and satellites to explore the cosmos. The field also includes various sub-disciplines such as astrophysics, planetary science, and cosmology, each focused on different aspects of the universe and its constituents.
