Skywatchers across the world will witness the first total lunar eclipse in three years. Here’s who will have the best views—and what gives the moon its eerie red tint.

A total lunar eclipse is sometimes called a blood moon thanks to the red or orange tinge it takes on from sunlight filtering through our planet's atmosphere. "It's as if all the world's sunrises and sunsets are projected onto the moon," NASA said. The color effect can be subtle, so don't expect a moon that's as red as a Corvette.

The celestial event in which the moon turns an eerie red color will occur on March 13 to 14 and will be visible in all 50 states.
