'Blood Moon' Lunar Eclipse Returns to the Sky on Wednesday

Here's why this lunar eclipse will have you seeing red.

— -- It's not Halloween just yet, but that doesn't mean the moon can't get a little freaky.

The phenomenon can be seen with the naked eye -- and will be visible to sky gazers in North America early Wednesday morning, with people on the Pacific coast getting the most breathtaking view.

The eclipse is the second in a rare series known as the tetrad, in which the moon is completely covered by the Earth's umbral shadow for four eclipses in a row, as opposed to only partial eclipses that fall in the outer penumbra.

The next total lunar eclipse will be on April 4, 2015, according to NASA.
