A total lunar eclipse will make the moon appear red across the Western Hemisphere during the "Blood Worm Moon" this week.

As the Full Worm Moon rose overnight, skywatchers across the Americas turned their eyes — and their cameras — toward the sky. Over several hours, Earth's shadow slowly crept across the lunar surface, turning our celestial neighbor into a deep, blood-red orb.

Earth’s shadow will block most of the light that illuminates the lunar surface, creating what is known as a blood moon.
