Galactic collisions or interactions between galaxies, offer profound insights into the dynamics, evolution, and growth of galaxies. These cosmic events, though often violent and chaotic, play a crucial role in shaping the structure and content of the universe. By studying interacting galaxies, astronomers gain valuable knowledge about the processes that drive galaxy formation and evolution, as well as the fundamental forces at play in the cosmos. When galaxies collide, they do not simply smash into each other like solid objects; instead, they pass through each other, causing complex gravitational interactions. These interactions lead to significant changes in the structure and dynamics of the galaxies involved. The gravitational forces exerted during a collision can trigger a cascade of events, including the compression of gas, the formation of new stars, and the redistribution of stellar and gas components. Observations of these processes provide key insights into the life cycles of galaxies and the mechanisms behind their growth and transformation.
