Blood Moon, 2022

This image of the totally-eclipsed moon was taken in the pre-dawn hours of November 8, 2022. Unlike a total solar eclipse that is viewable only along a narrow path of totality, a total lunar eclipse can be seen from the entire night side of the Earth.

A total lunar eclipse is also called a “blood moon”. The eclipsed moon is not totally dark – sunlight can reach the moon via refraction by Earth’s atmosphere. The reddish colour of the moon is due to the blue part of sunlight being scattered by Earth’s atmosphere, leaving primarily red and orange light reaching the moon – the exact same reason why the sun is orange during sunset.
