For the second time this year a total lunar eclipse occurred, Tuesday morning.

Known as the Blood Moon, the moon took on a red hue in the morning during the eclipse. It was visible from about 4-to-6 a.m. Tuesday.

A lunar eclipse happens when the sun, Earth and moon align. During a full lunar eclipse, the moon falls completely in the Earth’s shadow. There was a Blood Moon in May and there will not be another one for three years.
