Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Our Moon turned red last week. The reason was that during the night of January 20, a total lunar eclipse occurred. The above digitally superimposed photographs captured the Moon three times during this lunar eclipse , once just as the Moon entered the Earth's shadow , once when the Moon was near the middle of the shadow , and once just before the Moon exited. Differing amounts of clouds and volcanic dust in the Earth's atmosphere make each lunar eclipse appear differently.
