The next total lunar eclipse will be on Sept. 7-8, 2025, visible in parts of Asia and Australia, with totality lasting 82 minutes.

When sunlight hits Earth’s atmosphere during a lunar eclipse, light frequencies toward the blue end of the visible spectrum are scattered outward, away from Earth’s umbra, but those with longer wavelengths, toward the red part of the spectrum, are bent inward and cast onto the moon.

This month's full Worm Moon will arrive with a lunar eclipse in a rare celestial phenomenon known as a Blood Moon. The spectacular celestial display will be visible in the early hours of Friday morning (March 14), so stargazers in the UK might want to set an alarm to catch a glimpse of the partial lunar eclipse.
