Late on Sunday evening, there will be a total lunar eclipse that will be visible over most of North and South America, Europe and western Africa. This particular lunar eclipse will also happen to occur during a supermoon or wolf moon — that is, when the Moon’s slightly elliptical orbit brings it closest to Earth and it appears a bit larger in the sky.
During a total lunar eclipse — when the Earth is between the Sun and the Moon — the Moon turns a reddish-orange color, which is why it is sometimes called a blood moon.
