[00:00:00]Have you ever [music] looked up at a full moon and watched it slowly vanish into a dark [music] reddish shadow? That's a lunar eclipse and it's an incredible celestial cosmic dance.

[00:00:18]As the moon travels along its orbit, it occasionally passes directly [music] behind our planet. When the Sun, Earth, and Moon align in a perfectly straight line, Earth blocks the sunlight that normally [music] lights up the lunar surface.

[00:00:33]Instead of going completely dark, the moon often glows an [music] eerie deep crimson. This happens because Earth's atmosphere acts like a giant lens. It filters out the blue [music] light but bends the longer red wavelengths into our shadow, projecting [music] the glow of every sunset and sunrise on Earth onto the moon all at once.
