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

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

The March 2025 blood Moon lunar eclipse will be visible from the Earth’s Western Hemisphere, including the western half of South America and nearly all of North America. Locations farther east or west may still be able to see a partial lunar eclipse.
