Big Picture: Early Tuesday morning, the last total lunar eclipse until 2025 was visible across North and Central America (as well as in the evening in Australia and Asia). NASA explains that "A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow." When the Moon passes through the darkest part of the Earth's shadow, it has a reddish hue, which is why total lunar eclipses are sometimes called "blood moons."
What causes the moon to turn red? NASA science communicator Andrea Jones explains: "When the moon passes into Earth's shadow, the Earth blocks most of the light from the sun. But the sunlight that does reach the moon had to travel through a really thick chunk of Earth's atmosphere. So just like at sunrise and sunset, [when] the sky turns a bit red, if you were standing on the moon during a lunar eclipse, you would see that red. It's all the sunrises and sunsets on Earth being projected onto the moon at that time, that turns the moon red during a lunar eclipse."
