A blood moon is a term for the reddish appearance of the Moon during a total lunar eclipse. This occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. Sunlight passes through Earth's atmosphere, which scatters the blue light and allows longer-wavelength red light to pass through and reach the Moon, giving it its characteristic crimson colour.
