Summary:
- Stars can escape the gravitational pull of their host galaxy and travel through intergalactic space. This process is called "stellar stripping" and is caused by the interaction between galaxies.
- When two galaxies collide or pass close to each other, the gravitational forces can pull stars out of their original galaxies, sending them hurtling into intergalactic space. These "rogue" stars are no longer bound to any particular galaxy.
- The study of these escaped stars provides insights into the history and evolution of galaxies, as well as the distribution of matter in the universe. Understanding stellar stripping helps astronomers piece together the complex dynamics of galaxy formation and interaction.
