(“The temporary reddish hue is a normal byproduct of a total lunar eclipse. As the moon slips into the darkest part of Earth's shadow, called the umbra, it is blocked from the DIRECT light of the sun and is lit almost entirely by sunlight filtered through Earth's atmosphere, which scatters some components of light more than others. Blue light is mostly blocked, but red isn't. The result: Red light bathes the moon”) (emphasis added)
