What you need to know about a blood moon.
According to The Gaurdian, during a total lunar eclipse, the Earth, sun and moon are almost exactly in line, with the moon on the opposite side of the Earth from the sun. As the moon was full when it moved into the shadow of the Earth it dimmed markedly, but remained visible because of the sunlight passing through the Earth’s atmosphere.
So why was it reddish?
The sunlight passing through the Earth’s atmosphere was filtered and refracted in such a way that the green to violet light on the spectrum was scattered more strongly than the red light. This left more red light to reach the moon’s surface.
What did this moon look like from different places around the world?
