Like the Mayan Prophesy of 2012, the series of total lunar eclipses known as tetrad is causing speculation and a lot of explanation.
There are eight tetrads in the 21st century, but the ones in this tetrad are being remarked upon because they coincide with the full moon of Passover on April 15 and April 4, as well as the Jewish observance of Sukkot on Oct. 8 and Sept. 28.
In these eclipses the earth will block the sun's rays on the moon, causing the moon to appear dark red. That is why it is called the "blood moon."
"We are at this point in time when the earth and the moon and sun are spaced right to where the moon can perfectly block out the sun, and the earth can perfectly block out the moon," said Mike Sorola, who teaches at South San High School's new planetarium. "Then later the moon will be farther away and we won't get total lunar and solar eclipses."
Sorola said the blood moon will be visible at midnight April 15. He said it's science at work, nothing more except that it's also the Federal Tax deadline.
"I'm getting questions like, 'Is this like the 2012 Mayan calendar thing. Is this really the end of the world? Is it going to happen?' Nothing's going to happen," Sorola said.
The biblical implications being applied by some, however, come from Revelations 6:12. It reads, "I watched as He opened the sixth seal. There was a great earthquake. The sun turned black like sackcloth made of goat hair. The whole moon turned blood red."
Students of astronomy will tell you that through time all eclipses have been viewed with some degree of doomsday prophesy. It was a way to explain these dramatic scientific occurrences while lacking technological information we now have today.
