One of the most dramatic sights in the night sky—and inspiration for poets, artists, and lovers for millennia—full moons captivate us like nothing else.
Every month Earth's moon goes through its phases, waning and waxing in its constant transformation from new moon to full moon and back again.
Full moons occur every 29.5 days or so as the moon moves to the side of Earth directly opposite the sun, reflecting the sun's rays off its full face and appearing as a brilliant, perfectly circular disk.
For millennia, humans have used the movement of the moon to keep track of the passing year and set schedules for hunting, planting, and harvesting. Ancient cultures the world over have given these full moons names based on the behaviour of the plants, animals, or weather during that month.
