What is the field of science that studies stars, planets, and other celestial bodies?

• A. Astrobiology
• B. Astronomy
• C. Geology
• D. Cosmology

Answer: (B)

The field of science that focuses on the study of stars, planets, and other celestial bodies is astronomy. This branch of science encompasses the observation and analysis of celestial objects and phenomena outside Earth's atmosphere. It includes the study of the formation, evolution, and behavior of these bodies, such as their composition, structure, and motion.

Astronomy also encompasses various sub-disciplines, including astrophysics, which applies the principles of physics to understand celestial phenomena. This makes astronomy a broad and rich field that plays a crucial role in our understanding of the universe. In contrast, astrobiology deals with the study of the potential for life elsewhere in the universe, geology focuses on the Earth and its processes, and cosmology examines the origin and evolution of the universe as a whole. Each of these fields has a specific focus, but astronomy is uniquely dedicated to the observation and analysis of celestial bodies.
