Galactic Astronomy is the branch of astronomy that focuses on the study of galaxies, their formation, structure, and evolution. It examines the Milky Way, our home galaxy, as well as other galaxies in the universe, such as Andromeda and Triangulum. Researchers use telescopes and other instruments to observe the light emitted by stars, gas, and dust within these vast systems. This field also explores the interactions between galaxies, including mergers and collisions, which can lead to the formation of new stars. Additionally, Galactic Astronomy investigates the role of dark matter and dark energy in shaping the universe, providing insights into its overall structure and fate.
