Space in the context of astronomy and physics, refers to the vast expanse that exists beyond Earth's atmosphere. It is the almost empty, three-dimensional expanse in which all celestial objects, including stars, planets, galaxies, and other cosmic entities, exist and move. Space is characterized by a near absence of matter, with extremely low densities of gas and dust particles.
Astronomy is the study of celestial objects and phenomena beyond Earth's atmosphere. Astronomy involves observation and analysis using telescopes and instruments to learn about the properties, movements, and compositions of these objects. Key aspects of astronomy include cosmology, stellar astronomy, planetary science, galactic and extragalactic astronomy, astrobiology, and the investigation of cosmic phenomena.
