Question

Quizplus · Accepted Answer

Tidal tails, multiple nuclei, and shells of stars are all features that occur as a result of galaxy interactions, such as mergers or close encounters between galaxies. These interactions can disrupt the original structures of galaxies and create these characteristic features. As such, they are primarily observed in galaxies that have experienced recent interactions with other galaxies.
