'Super blue blood moon': Lunar trifecta glows in night sky
Skywatchers in some parts of the world witnessed a rare combination of events that included a total lunar eclipse.
The shadow of the earth passes over the moon during the beginning of a total lunar eclipse on Jan. 31, 2018.
The moon is putting on a rare cosmic show. It's the first time in 35 years a blue moon has synced up with a supermoon and a total lunar eclipse.
The Earth's shadow covers the moon on Jan. 31.
The full moon was a rare combination of a blue moon (the second full moon in a single calendar month), a supermoon (a moon that's full when it's at its closest point in its slightly elliptical orbit around Earth), and a total lunar eclipse or blood moon. In the U.S., the best views of the eclipse were on the West Coast.
