Hubble's WFC3 image reveals the crowded core of Omega Centauri, a massive globular cluster with 100,000 stars. Captured post-2009 installation, it shows stars in various stages: yellow-white fusing hydrogen, orange giants, blue helium-fusers, faint blue white dwarfs, and "blue stragglers" from collisions. Stars here are just a third of a light-year apart, suggesting remnants of a disrupted galaxy.
