When Earth passes directly between the Sun and the Moon, sunlight filters through Earth’s atmosphere and bends toward the Moon.
Shorter wavelengths (blue light) scatter, while longer wavelengths (red and orange) continue through — giving the Moon its deep blood-red glow.
It’s the same physics that makes sunsets red… except here it’s happening 384,000 km away in space.
Seeing it reminds you how perfectly aligned the universe has to be for moments like this.
