NGC 288: The First "Splashed" Globular Cluster?

NGC 288 appears to be the first known "Splashed" globular cluster—originally formed in the Milky Way but later thrown into a new orbit by the Gaia-Sausage-Enceladus (GSE) merger. Despite its accreted-like motion, its age and chemical composition match in situ clusters, suggesting it was born in the Milky Way. This study highlights how ancient galaxy mergers reshaped the Milky Way's structure, potentially affecting other globular clusters in similar ways.
