A "Galaxy Pair" refers to two galaxies that are in close proximity to each other in space. These pairs can interact through gravitational forces, leading to various phenomena such as tidal distortions and star formation. Galaxy pairs can be found in different stages of interaction, from merely passing by each other to merging into a single galaxy over time. Studying galaxy pairs helps astronomers understand the evolution of galaxies and the dynamics of the universe. Observations of these pairs can reveal insights into the formation of structures like galaxy clusters and the role of dark matter in shaping the cosmos.
