The term for the study of celestial bodies and outer space is astronomy. This field encompasses the investigation of planets, stars, galaxies, and the universe's structure and origin. Astronomers use a variety of tools, including telescopes and space probes, to observe celestial phenomena and gather data on physical and chemical processes in the cosmos. Discoveries in astronomy have profound implications for our understanding of time, space, and the fundamental laws of physics. Moreover, it sparks questions about the potential for life beyond Earth and the universe's fate.
