This blood moon was captured over Mount Crested Butte in Colorado. What does ‘blood moon’ refer to?
A A full moon near Halloween
B A total lunar eclipse
C Any full moon with a red hue
The night of September 27, 2015, was a perfect night in the Colorado Rockies to see the blood moon, as full lunar eclipses are often called. That’s because the filtered sunlight casts a reddish glow across the moon as it moves behind the Earth’s shadow. Tonight, most of the Pacific side of the planet will be treated to another full lunar eclipse, coinciding with a full moon. While partial lunar eclipses are fairly common, full ones are rarer, although not as rare as solar eclipses.
The correct answer is A total lunar eclipse.
