'Blood moon' sweeps night sky

A "blood moon" rises over the El Salvador del Mundo monument in San Salvador early Tuesday, April 15, as a total lunar eclipse attracts sky gazers across the Americas. In a total lunar eclipse, the full moon turns a coppery red as it passes into Earth's shadow. "It's like seeing all the sunsets on Earth projected on the moon at once," says Indra Petersons of CNN's "New Day."
