Galaxy Pairs
Galaxy pairs are systems where two galaxies are in close proximity to each other, often interacting through gravitational forces. These pairs can be found in various stages of interaction, from merely passing by each other to merging into a single galaxy. The study of galaxy pairs helps astronomers understand galaxy formation and evolution.
The interaction between galaxy pairs can lead to significant changes in their structures and star formation rates. For example, when two galaxies collide, their gas and dust can trigger new star formation, resulting in bursts of activity. Observing these pairs provides valuable insights into the dynamics of the universe and the life cycles of galaxies.
