The celestial symphony of NGC 6496: A cluster of heavy-metal stars

Scottish astronomer James Dunlop discovered the globular cluster NGC 6496 in 1826, which resides in the constellation of Scorpius. This cluster is notable for its high metallicity stars and variety of variable stars, offering valuable insights into star formation and galactic evolution. Recent research reevaluates its classification, with some suggesting it may belong to the halo clusters.
