Super Blue Blood Moon

The Moon is seen as it sets behind the National Capitol Columns at The US National Arboretum on Wednesday, Jan. 31, 2018 in Washington. Today’s full Moon is unique for three reasons: it is the third in a series of supermoons, occurring when the Moon is closer to Earth in its orbit. It is also the second full moon of the month, commonly known as a blue moon. The moon will also be passing through Earth’s shadow, giving skywatchers in the right locations a view of a total lunar eclipse. Photo Credit: (NASA/Aubrey Gemignani)
