How Long Until the Blood Moon Lights Up the Sky Again? You Must Know! The Blood Moon—also known as a lunar eclipse—has captivated stargazers and astronomers for centuries. This striking celestial event, where the Moon takes on a deep crimson hue, happens during a total lunar eclipse when Earth blocks direct sunlight from reaching the Moon, casting a reddish glow across its surface. If you’re wondering, “How long until the next Blood Moon lights up the sky?” here’s everything you must know about these rare but awe-inspiring phenomena. ### What Causes the Blood Moon? A Blood Moon occurs during a total lunar eclipse, a moment when the Sun, Earth, and Moon align perfectly in syzygy. As Earth passes directly between the Sun and the Moon, it casts a shadow across the lunar surface. While the Moon enters Earth’s outer, reddish-shaded partial shadow (the penumbra) well before totality, the dramatic red “Blood Moon” effect emerges during totality, caused by sunlight scattered through Earth’s atmosphere—much like during sunsets and sunrises.
