Elliptical Galaxies | Vibepedia

Elliptical galaxies are smooth, ellipsoidal masses of predominantly old, red stars with minimal gas and dust, preventing new star formation. Classified by **Edwin Hubble** from E0 (nearly spherical) to E7 (highly elongated), they dominate galaxy clusters and harbor supermassive black holes at their cores. Often formed through mergers, these 'red and dead' giants reveal the universe's evolutionary history through their serene, featureless glow.
