Description: On January 21st 2019, the Moon passed entirely into the Earth's shadow in an event known as a total lunar eclipse. During this event the Earth was blocking any direct sunlight from reaching the Moon, meaning that the only light reaching the Moon had been refracted by Earth's atmosphere. Since Earth's atmosphere scatters blue light more than it does red light, the refracted sunlight was red and as such the Moon appeared to be red during the eclipse. This is sometimes referred to as a "blood moon". Due to the Moon being at the point in its orbit closest to Earth, it also appeared slightly larger than usual (a "super moon"). In addition, the moon was a "wolf moon" (the first full moon of the year), giving this particular eclipse the title of "Super Wolf Blood Moon". This series of images, taken at different times throughout the eclipse, was taken at the Roque de Los Muchachos Observatory in La Palma, Canary Islands, Spain. Credit: Luke Holden.
