On December 4, 2025, skies around the world illuminated under the final full moon of the year: the so-called Cold Moon — a stunning blend of lunar beauty, seasonal chill, and cosmic timing. Space+1

Because the Moon passed unusually close to Earth during its monthly orbit (a point astronomers call perigee), this “Cold Moon” also qualifies as a supermoon — making it appear up to 14% larger and 30% brighter than a typical full moon. Space+1

For stargazers, that meant a rare treat: a glowing lunar disk rising at dusk, larger and more luminous than most moons — the perfect final celestial show before the dark deep of winter sets in.

🔭 When & How to Watch (or See Later)

• Peak full illumination: December 4, 2025 (exact timing varies by timezone). Space+1

• Best viewing: Look east at sunset — when the moonrise meets the horizon, you’ll get the biggest, most dramatic view. Once up, the moon stays visible all night. Sky at Night Magazine+1

• Pro tips:

  • Use binoculars or a small telescope to spot craters and maria — the bright light still lets surface details pop.

  • Try shooting moonrise over a skyline, skyline with trees, or natural foreground — the contrast gives dramatic photos.

🎇 A Lunar Show with Room for More

The 2025 Cold Moon is now behind us — but that doesn't mean the sky opens close. Full moons, meteor showers (like the upcoming Geminid meteor shower), planets, and deep-sky objects still await.
If you missed the Cold Moon, keep your binoculars ready: the universe never stops showing off.
