A lunar eclipse happens when the Earth slips between the sun and the moon, casting a long shadow on the lunar surface and darkening it. But sunlight filters in through the edges of the Earth’s atmosphere, casting a reddish-orange glow on the moon. This light is a projection of all the sunrises and sunsets happening on Earth at this time, creating a spectacular cosmic show.
