A total lunar eclipse will be visible tonight across the Western Hemisphere, for those willing to stay up late.

Early Friday morning, the Earth moved between the sun and the moon, casting its shadow on the lunar surface and turning it into a full blood moon. It was quite early in the morning, though. Like 1 a.m.

Night owls and astronomy enthusiasts will want to look up in the skies late tonight in Colorado, and hope there aren’t too many clouds to see the moon.
