Despite the astronomical event being a regular occurrence throughout history, many cultures and religions have tried to attribute blood moons as signs of impending catastrophe. There is an apocalyptic prophecy about the Blood Moon, liked to the Bible. The first eclipse in the prophesied tetrad took place on April 15, 2014, and was followed by Blood Moons on October 8, 2014, April 4, 2015 and September 28, 2015. And there is no reason to believe the Blood Moon is a sign from the heavens because scientists understand very well the mechanics behind why the moon turns red during an eclipse.
The effect is known as Rayleigh scattering and the phenomenon is responsible for painting the skies blue and sunsets red. During an eclipse the moon will pass directly behind the sun and Earth to hide in the planet’s shadow. In what seems like a bizarre coincidence, Mars will also observe the closest distance from Earth in 15 years during the July lunar eclipse. Mars will easily be visible to the unaided eye under a clear sky.
