As with all such reports, only the results will teach what is the truth! Four blood moons will make for a series of interesting events, regardless of the outcome.
"Sky watchers are getting ready for an evening of special viewing when a total lunar eclipse arrives just after midnight on April 15.
What's more, this begins a rare sequence of four total lunar eclipses expected over the next two years"
"As it begins, "the Earth's shadow will make a slow crawl across the moon's face, appearing as if there is an increasingly large 'bite' taken out of the moon," said Deborah Byrd with EarthSky.org, an online science magazine.
At first, the full moon will just appear to be a little darker than normal, "but eventually people will notice a much darker arc moving across the moon, with a distinct rusty reddish-brown color," said astronomer Gerald McKeegan at the Chabot Space and Science Center in Oakland, Calif.
The bloody red color the moon takes on during an eclipse is caused by refraction of sunlight by the Earth's atmosphere".
