April's Pre-Easter 'Blood Moon': Bring Out the Conspiracies

For the third time in two years, stargazers and apocalyptic doomsayers Saturday are getting their fill of unique celestial events with a total lunar eclipse.

Lunar eclipses happen about twice a year when the moon passes directly behind the Earth into its shadow, or umbra. Total lunar eclipses, or "blood moons" are a little more rare.

But what's up with the creepy red glow that gives the lunar event its nickname?

Well, the red color is actually not unlike a sunset, but from the moon's perspective. NASA describes it as "seeing every sunrise and every sunset in the world, all of them, all at once." And that red glow from behind the Earth gets projected onto the moon.

This total lunar eclipse is the third in a series of four appearing every six months, a phenomenon called a "tetrad" – something not particularly rare for this century according to NASA.

LAS VEGAS, NV - APRIL 04: The moon is shown during a brief total eclipse, the shortest one this century, as it skims the Earth's shadow on April 4, 2015 in Las Vegas, Nevada. It is the third in a lunar tetrad - four consecutive total lunar eclipses with no partial lunar eclipses in between them. The orange glow of the moon is a result of sunlight scattered off Earth's atmosphere giving it the nickname 'blood moon.' The next full lunar eclipse will occur on Sept. 28, 2015.

While a total lunar eclipse is a fun night sight for skywatchers, for others the oncoming blood moon and tetrad brings something else – tidings of doom.

As CTV News points out, a number of conspiracy sites suggest links between lunar eclipses and major historical events, including the fall of Constantinople and the founding of the State of Israel. In fact, the last blood moon outside this current tetrad occurred when the Red Sox won the World Series in 2004.

But perhaps the biggest proponent for any conspiracy concerning the upcoming blood moons is Pastor John Hagee, who released a book titled "Four Blood Moons: Something Is About to Change in 2013."

In a 2013 interview with Fox News, Hagee emphasized the significance that each blood moon will occur during a Jewish holiday.

"To have a blood moon, and then for those blood moons to be on this exact date, is something that just is beyond coincidental."

All four of this recent set of blood moons are viewable from the U.S., which Hagee claims is further proof of impending doom in America.

The last of the four blood moons in this tetrad will be viewable later this year on September 28.

LOS ANGELES, CA - OCTOBER 8: A religious cross is seen as the moon is illuminated by sunlight reflected off the Earth during a total lunar eclipse, one of four so-called 'blood moons', on October 8, 2014 in Los Angeles, California. The first in the current tetrad of blood moons fell on Passover and the current eclipse occurs on the Jewish holiday of Sukkot, the fifth day after Yom Kippur, leading some religious people to believe that it is a prophetic sign of the end times of civilization. This blood moon appears 5.3% larger than the last one on April 15 because it occurs right after the perigee, the closest point in its orbit to the Earth. (Photo by David McNew/Getty Images)
