The Science Behind Blood Moons

Blood Moons are a Result of Total Lunar Eclipses. They occur when the Earth comes directly between the Sun and the Moon, casting a shadow that envelopes the Moon. Unlike a solar eclipse where the Moon blocks the Sun, a lunar eclipse allows the Earth’s shadow to fall on the Moon.

• Atmospheric Scattering: The reddish hue, the hallmark of a Blood Moon, results from Rayleigh scattering, the same process responsible for vibrant sunsets. When sunlight passes through Earth’s atmosphere, the shorter blue wavelengths scatter, leaving the longer red wavelengths to illuminate the Moon.
• Timing and Frequency: Blood Moons can only occur during a full moon and typically happen over several hours. They are relatively rare, with about one to three occurring each year.

• Mythology and Legends: Ancient civilizations often interpreted them as signs of divine displeasure. For instance, some Native American tribes viewed them as a cosmic chase between celestial animals.
• Influence on Astronomy: These events allowed early astronomers to study the orbit and composition of both the Earth and the Moon. They contributed to early understandings of Earth’s atmosphere and lunar behavior.
