On Sunday, May 15 and Monday, May 16, a lunar eclipse will occur. This astronomical phe nomenon occurs when the sun, Earth, and moon line up properly for the moon to pass into the Earth's shadow. Roughly three times a year, the moon passes through at least par t of the Earth's shadow. Because our moon's orbit is tilted, lunar eclipses do not occur every time the moon makes its monthly trek around our planet. It can only happen during a full moon, so we are likely to experience it just twice a year. To catch a glimpse of the lunar eclipse and "blood moon," you'll have to stay awake late into the night and early morning. The term "blood moon" is used by many astronomy experts and writers to describe the rusty orange or reddish color glow the moon becomes from the light reflecting from the sun. Learning Ally has many enjoyable and informative audiobooks about the sky, the sun, astronomy, and our universe. Search on a specific category or use keywords to find titles that will interest learners of any age in our Browse Audiobooks section. For additional resources, PBS has excellent videos to demonstrate the mechanics of lunar eclipses to view and engage students with visualizations that show the alignment of the Moon, the Sun, and Earth from multiple perspectives. Happy sky watching!
