WHAT IS A BLUE MOON?
The term is used when a full moon occurs twice in the same calendar month. It happens every 2.7 years and never in the month of February because there are not enough days. Is the moon really blue, though? It depends! Most moons are not blue, but if there is a volcanic eruption or even a forest fire, the smoke in the sky can turn the moon a blue color. |
