September 2025 is a total lunar eclipse which occurs only when the Earth perfectly aligns between the sun and the moon. This allows to cast its central shadow also known as umbra across the lunar surface. As a result, the moon glows in shades of red and orange as sunlight bends through Earth's atmosphere, filtering out blue wavelengths.
