Galaxies can suddenly stop forming stars when their gas supply is disrupted or exhausted. Powerful black hole eruptions, supernova winds, or collisions strip away the fuel needed for star birth. Without fresh gas, galaxies enter a “quenched” state, appearing older and redder. This cosmic mystery reveals how delicate the balance of star formation is, and why some galaxies evolve faster than others. Understanding this process helps astronomers unlock secrets of galactic life cycles and cosmic evol
