For the night owls up early Tuesday morning a the moon turned red as it dipped into the shadow of the Earth. The phenomena, referred to as a "blood moon" occurs only a few time each year.
"That's what they call it because of the color, but what it is, is a lunar eclipse," said YSU Professor Patrick Durrell.
He teaches astronomy courses and said the color is cast by the small amount of light that bends through the Earth's atmosphere during the eclipse. The eclipse he said would begin to "bite"out of the moon at about 2 a.m. and come to full by about 3:30 a.m.
In history, Durrell said the shape of eclipses was part of what taught the Greek people that the Earth was round. Today he said the shape is the same but people shouldn't need an eclipse to tell.
"I certainly hope they don't," he said.'
