The Southern Taurid meteor shower peaks overnight on November 4–5, 2025, bringing a rare “swarm year” filled with bright fireballs from Comet Encke’s debris. Skywatchers can expect slow, glowing meteors—some as bright as fireballs—despite interference from the nearly full Moon. Experts predict up to 10 visible Taurid meteors per hour under dark, clear skie…
