August is a month that often brings to mind the height of summer, with long, warm days and star-studded nights. This year, the celestial show is even more enchanting, beginning with a New Moon today and culminating in a spectacular full moon on the 19th. This August full moon is particularly special as it will be a seasonal blue moon—a rare occurrence that happens when there are four full moons in a single astronomical season instead of the usual three. When this happens, the third full moon of the four is designated as a blue moon. This type of blue moon is a rarity, with the last one appearing in August 2021, and the next not expected until May 2027.
