A super blue blood moon sets early morning Jan. 31, 2018, Travis Air Force Base, Calif. This full moon is special for three reasons: it’s a “supermoon,” when the Moon is closer to Earth in its orbit -- known as perigee -- and about 14 percent brighter than usual. It’s also the second full moon of the month, commonly known as a “blue moon.” The super blue moon will pass through Earth’s shadow to give viewers in the right location a total lunar eclipse. While the Moon is in the Earth’s shadow it will take on a reddish tint, known as a “blood moon.” (U.S. Air Force Photo by Heide Couch)
