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 occurs when the Earth is positioned directly between the moon and sun, blocking the sun's rays from the moon.

On the night of March 13-14, 2025, all 50 U.S. states will witness a total lunar eclipse — the best “blood moon” until 2029. Totality will last 65 minutes.
