Skywatchers worldwide witnessed 2025's last cosmic spectacle as December's Cold Moon – the year's third and final supermoon – illuminated night skies this week! 🌌
Beijing Planetarium engineer Wen Kou explains this phenomenon occurs when a full moon aligns with perigee (the moon's closest Earth approach). This makes our lunar neighbor appear 14% larger and 30% brighter than usual – like nature's own Instagram filter! 📸
This December 5 showstopper followed November's slightly larger supermoon, though experts say only trained eyes could spot the size difference. "Both looked equally stunning to most observers," Kou noted during a live planetarium broadcast.
🌍 Global Highlights:
Peaked at 7:14 AM Beijing Time (12/5)
Occurred during Northern Hemisphere's coldest nights
Final supermoon until 2026
Missed it? Don't moon over it – mark your calendars for 2026's first supermoon predicted in April! 🔭
