Category Description: Science is a rigorous, systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the world. Modern science is typically divided into three major branches: natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules.

Q13. What is the scientific field dedicated to the study of heavenly bodies, celestial objects, and phenomena originating beyond Earth's atmosphere?
Q13. What is the scientific field dedicated to the study of heavenly bodies, celestial objects, and phenomena originating beyond Earth's atmosphere?
Answer: (D) Astronomy
Answer: (D) Astronomy
Answer: (D) Astronomy
Astronomy is a natural science that involves the scientific study of celestial objects (such as stars, planets, comets, galaxies, and nebulae), the universe as a whole, and the phenomena that originate beyond Earth's atmosphere. It uses principles of mathematics, physics, and chemistry to understand their origin, evolution, physical and chemical properties, and behavior. While cosmology is a branch of astronomy that focuses on the universe's origin, evolution, and large-scale structure, astronomy encompasses the broader study of all extraterrestrial objects and phenomena.
