Astronomers have studied the globular cluster 47 Tucanae extensively, but still have many questions. It may have an intermediate mass black hole in its center like Omega Centauri is expected to have. There are reasons to believe it may be the remnant of a dwarf galaxy that was gobbled up by the Milky Way, like other GCs. Also like other GCs, its center is extraordinarily dense with stars, and astronomers aren't certain how far the cluster spreads.
