Why is December's Cold Moon special this year?
This year's Cold Moon is particularly special because it coincides with a supermoon, making it appear larger and more luminous than typical full moons. Named by Native Americans, the Cold Moon marks the start of winter and is the last full moon of 2025. Its brightness and timing make it a unique sight, especially when viewed alongside other celestial events happening this month.
