This Friday, July 27, the world will experience an unrepeatable event: the Moon will be painted completely red for about 1 hour and 43 minutes, being the longest lunar eclipse of the century.
The color change is due to sunlight filtering and refracting the Earth’s atmosphere. The earth acts as a lens that deflects light from the Sun and filters its blue components, in a way that only lets through the red light reflected by the satellite. This is how the Moon acquires that characteristic coppery glow.
The lunar eclipse can be fully observed in Africa, Asia and in certain regions of Europe, but not in Mexico. The inhabitants of the American continent will be able to see it on the internet or on television through a live broadcast.
