Moon Phase Today: Waning Crescent on May 15, 2026

This article provides an astronomical update regarding the Moon's appearance on May 15, 2026. According to NASA's Daily Moon Guide, the Moon is currently in the Waning Crescent phase, with only 4% of its surface illuminated. Consequently, visibility is extremely low, making it difficult to observe any surface features with the naked eye. The text explains that the Moon is approaching the New Moon stage, after which visibility will gradually increase. Additionally, the report highlights that May 2026 features two Full Moons, with the next one scheduled for May 31. The article also includes an educational section detailing the eight distinct phases of the lunar cycle, such as New Moon, Waxing Crescent, First Quarter, and Full Moon. It explains that these phases result from the changing angle of sunlight as the Moon orbits Earth over approximately 29.5 days.
