A blood-red moon will soon grace the skies for a total lunar eclipse, visible from North America, Central America, and parts of South America on Tuesday morning, with Australia and eastern Asia able to catch it Tuesday night. Solar and lunar eclipses occur due to the alignment of the sun, moon, and Earth, with between four and seven happening each year. During a total lunar eclipse, Earth’s shadow covers the moon, giving it a red hue as sunlight filters through the atmosphere. The upcoming eclipse is followed by a partial lunar eclipse in August, visible across the Americas, Europe, Africa, and west Asia.
