For the first time in 2 ½ years, the moon was in full eclipse Tuesday morning.
You may have noticed it — from 12:58 to 4:33 a.m. — when the phenomenon was visible across North America and the moon appeared to change colors.
A total lunar eclipse happens when the moon passes through the Earth’s shadow when the moon is full. Some people refer to it as a blood moon because the moon can appear to be red.
Most of the time, said Jack Dunn at Mueller Planetarium in Lincoln, Neb., the moon appears burnt orange.
“Since the light you see is sunlight reflected off of the Earth, it depends on Earth’s atmosphere for the amount of filtering. If we had any recent large volcanic eruptions, that might make it more red. But this time, probably not,” he said in an email.
