A "Red Moon," often referred to as a Blood Moon, occurs during a total lunar eclipse when the Earth passes between the Sun and the Moon. This alignment causes the Earth's shadow to cover the Moon, filtering sunlight through the atmosphere and giving it a reddish hue. The phenomenon is a natural result of Rayleigh scattering, similar to how sunsets appear red. The appearance of a Red Moon can vary in intensity and duration, depending on the specific conditions of the eclipse. While it is a captivating sight for skywatchers, it is also a reminder of the dynamic interactions between celestial bodies in our solar system.
