There are a number of compelling reasons to catch the looming March 13-14 total lunar eclipse, which will be visible in the entire lower 48 states and greater Americas.
Perhaps the best one is that no two such eclipses are the same. That means, weather permitting, you’ll witness something unique.
Total lunar eclipses occur when the sun, Earth, and moon are in alignment, allowing Earth to cast a shadow on the moon and block most sunlight from reaching the lunar surface. But our planet’s atmosphere still allows red wavelengths of light to squeeze through, illuminating the moon in reddish, rusty, orangish, or crimson colors. Crucially, both the fickle conditions in Earth’s atmosphere, and how deeply the moon passes through Earth’s shadow, impact how light is ultimately projected onto the moon. This means different, and even unexpected, light shows.
“It’s part of the thrill,” Bennett Maruca, an astronomer at the University of Delaware who has witnessed a number of total lunar eclipses, told Mashable. “You don’t know exactly what you’re going to get.”
