Astronomy vs. Cosmology: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Astronomy is the scientific study of celestial objects and phenomena, while Cosmology focuses on the origin, evolution, and ultimate fate of the universe as a whole.
Key Differences
Astronomy involves the detailed study of stars, planets, galaxies, and other celestial bodies, focusing on their properties, behavior, and interactions. Cosmology, however, delves into the larger scale of the universe, exploring its origin, structure, dynamics, and eventual fate.
