What we learn?
There's a scene about a full-red-blooded-moon called Blood Moon by Langston. Is red Moon really possible to happen?



red moon

Answer?
Yes, it is highly possible and happen a lot.

Why? What's the cause?
Here's simple explanation:
When the moon is low on the horizon the sunlight reflecting from it must pass through a lot more of our atmosphere before it reaches your eyes than it does when it is further up in the sky, or right overhead. Pollution, dust, and even humidity makes the air act like a filter blocking out some of the light. What reaches us are the longer wavelengths that are in the red and orange parts of the spectrum. It is the same effect that makes a sunrise, or sunset glow with a red, or orange hue.

During a total lunar eclipse the moon will appear red also as the sun's light is filtered through the Earth's envelope of air.

Rant:
The red moon shown on this episode looks like in middle of the night, not dusk. The position seems not in the horizon. I don't know if it's still possible to see red-moon in the midle of the night, maybe if the sky is so dusty it will happen.
