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. Individual stars in 47 Tuc are difficult to observe because they're so tightly packed in the center and because they're difficult to differentiate from field stars on its outer edges. Can the Vera Rubin Observatory help?

When Theia Struck Earth, it Helped Set the Stage for Life to Appear
How did Earth, alone among the Solar System's rocky planets, become the home for life? How, among all this frigid lifelessness, did our planet become warm, hospitable, and life-sustaining?
