Sunday night, the sky looked wicked cool, and the moon looked bloody red. It won’t appear that way again until 2033.
The so-called “blood moon” can be seen during a total lunar eclipse–a rare astronomical event when a swollen “supermoon” and lunar eclipse combined for the first time in decades.
Sky-watchers around the world were treated to a rare sight when the shadow of Earth cast a reddish glow on the moon, the result of an eclipse with the closest full moon of the year. This combination last occurred in 1982, and won’t happen again until 2033.
