Pictures of last night's "Blood Worm Moon," a total lunar eclipse, show the full moon looking red in the night sky.

In the Americas alone more than one billion people in 35 countries could bear witness to the total lunar eclipse.

Early risers were able to witness a partial lunar eclipse – or “blood moon” – before dawn on Friday. A “blood moon” is created when the moon moves into Earth’s shadow, gradually darkening before turning red.
