March's full "Blood Worm Moon," a phenomenon that makes the moon appear red during a total lunar eclipse, is visible this week for Americans and others in Earth's Western Hemisphere.The full moon reaches peak illumination at 2:55 a.

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

The coming March 13-14 total lunar eclipse promises to be spectacular — if the weather permits. This "blood moon" — the first to grace Earth's skies since 2022 — will be visible to people in the lower 48 states and greater Americas unless clouds get in the way.
