Colors of the Moon 500 Piece Puzzle from Galison highlights the colors of the full moon, documented by astrophotographer Marcella Giulia Pace from different locations in her native Italy, over a 10-year period. Red or yellow moons often indicate a moon being seen near the horizon. Blue-colored moons are rarer and can indicate a moon seen through the atmosphere carrying larger dust particles.
