The moon appears red tonight, August 3, 2025, primarily due to its close alignment with the red supergiant star Antares in the constellation Scorpius. This rare celestial conjunction bathes the moon in a reddish tint enhanced by the star's bright, fiery light. Additionally, atmospheric scattering of light, especially when the moon is low on the horizon, filters out shorter wavelengths, leaving the longer red wavelengths visible and deepening the moon's red or orange hue. This phenomenon is not related to a lunar eclipse or a traditional "blood moon," but rather a spectacular visual effect from this unique star-moon alignment combined with Earth's atmospheric effects.
