Skywatchers are gearing up for a rare celestial event that’s set to adorn the night skies across the United States, Canada, and Mexico. A total lunar eclipse will cast a shadow on the Moon, turning it into a spooky red color for one night. Here’s how you can watch it unfold.

A total lunar eclipse will flush the moon blood red Thursday night into Friday morning across the Western Hemisphere.

A total lunar eclipse occurs when the moon moves into Earth’s shadow, and this eclipse will last for just over an hour. But you’ll need to be a night owl (or an early riser) to catch it, it happens from 1:26 a.m. to 2:32 a.m. Central Time.
