Last night’s moon had the special distinction of being a rare kind of Blue Moon. And according to several publications, to see it, all you had to do was look up.
According to AOL’s Skye the “full moon qualifies as a Blue Moon because it's the third full moon in a season with four, (most seasons have only three.)”
According to Skye, full moons occur every 29.5 days on average, when the moon is directly opposite the sun.
“This causes its whole disk to be fully illuminated as a large, bright circle,” Skye authors wrote. Usually, when the moon is full, it passes either above or below Earth's shadow, but sometimes, when it is perfectly aligned, it travels right through the shadow, causing a lunar eclipse, when its disk is dark.”
