"Full moon" as a trend category encompasses everything from lunar cycles to eclipse mania. At its core, a full moon occurs when the Earth is positioned between the sun and the moon, casting the latter in a glowy, ethereal light. From there, the trends veer in every direction, from ancient lunar festivals like the Hindu Purnima and Amavasya to modern-day celestial events like the 2024 hybrid solar eclipse. Astrology buffs can revel in tarot cards like the Two and Four of Wands, while the more scientifically minded can geek out on the Moon Express, which plans to explore the lunar surface. In short, "Full moon" reflects a wide-ranging fascination with our celestial neighbor and all its magical and scientific mysteries.
