Omega Centauri (NGC 5139) - Largest Globular Cluster in the Milky Way #1796084 (License: Personal Use)

This high-resolution image captures Omega Centauri (NGC 5139), the largest and brightest globular cluster in the Milky Way, containing an estimated 10 million stars packed into a spherical region just 150 light-years across. Its dense core and symmetrical halo reveal ancient stellar populations, some over 12 billion years old, offering insights into galaxy formation and stellar evolution. The cluster’s unusual chemical composition suggests it may be the remnant core of a dwarf galaxy absorbed by the Milky Way.
