Galactic evolution is a field of study within astronomy that focuses on the formation and development of galaxies over time. This research area aims to understand how galaxies form, evolve, and interact with each other in the universe. Scientists study the composition, structure, and dynamics of galaxies to gain insights into their evolution and the processes that shape them, such as star formation, merging, and interactions with dark matter. By examining the properties and history of galaxies, researchers can uncover the underlying mechanisms that drive their evolution and impact the overall structure of the universe.
