What Is A Super Blue Blood Moon?
Noah Petro, a scientist for the NASA Goddard Space Flight Center, said in an interview:
“The super blue blood moon is simply the coincidence of three lunar events: A super moon, a blood moon and a blue moon.”
A blood moon is a term used to describe a total lunar eclipse, which is when the moon appears darkened as it passes through the Earth’s shadow. The total lunar eclipse is given the “blood” nickname because of the “beautiful” red color caused by the projection of all of the Earth’s sunrises and sunsets onto its surface, Petro said. The next lunar eclipse visible in the U.S. will be on Jan. 21, 2019, according to NASA. It won’t be a blue moon, but it will be a super moon.

A super moon is a full moon or new moon that coincides with the moon’s position at its closest to the Earth. Wednesday’s super moon will be the second-closest full moon of the year, after the one that occurred on Jan. 1, Petro said. It will also be part of a “trilogy” of recent super moons, the first of which occurred on Dec. 3, according to NASA.
A blue moon is merely a “quirk in the calendar,” as the second full moon in a month, Petro said, adding that there is “nothing really to see there.”
“In the early morning hours of Jan. 31, the moon will transform to a reddish hue as becomes completely submerged in the Earth’s shadow.”
