The planet Mars won’t be the only red object in the night sky tomorrow. If you happen to be up before dawn, check out the moon around 3 a.m. If the weather is clear, Earth’s celestial neighbor will take on a reddish tone during a total lunar eclipse.
John French is the interim director of the Abrams Planetarium at Michigan State University. Current State’s Kevin Lavery asked him to describe the spectacle of watching the moon pass through the Earth’s shadow. He says The last tetrad was in 2003 and 2004, and the next will be in 2032 and 2033.
