How Omega Centauri connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
The barred spiral galaxy that contains the Solar System, the Sun, and all stars visible to the naked eye.
Stars fall into broad populations: metal-rich Population I stars in the disc, like the Sun; old, metal-poor Population II stars in the halo and globular clusters; and a hypothesised first generation of metal-free Population III stars, not yet directly observed. Star clusters — young open clusters and ancient globulars — are coeval populations that serve as the great testing grounds of stellar-evolution theory.
A dense, roughly spherical swarm of tens of thousands to millions of very old stars, tightly bound by gravity and orbiting in the halo of a galaxy. Globular clusters are among the oldest structures in the Universe, and their tightly packed, coeval stars make them benchmarks for stellar ages and the early history of the Galaxy.
