Louisville, KY – A total lunar eclipse will start just after midnight tonight. In a total lunar eclipse, the earth blocks the sun's rays from reaching the moon. It can be easily observed with the naked eye and it looks like the full moon is disappearing. Tim Dowling is a physics and astronomy professor at the University of Louisville. He says if conditions are right, watching the eclipse unfold can change the way you look at the sky.
"What really is neat is you can see the sky is three-dimensional. You know, usually the sky is really flat, but you look up and you see the moon going into the shadow of the earth - all of a sudden you get a sense of how three-dimensional everything is."
If you can't stay up that late, or the skies are cloudy, your next chance to get a clear view of a total lunar eclipse is in 2014.
