Q:

What is the meaning of a red moon?

A:

Quick Answer

Scientifically speaking, there are three meanings for a red moon: that there is a lunar eclipse, that the moon is near the horizon and the light is passing through a larger amount of atmosphere or that particles in the air (from events like a forest fire or a volcanic eruption) are partially obscuring the light. Any of these conditions cause the light from the moon to be partially scattered, eliminating the blue and green parts of the visible light spectrum so that only red light filters through.

Full Answer

A lunar eclipse is one of the more predictable causes of a red moon. Because the red moon is caused by a certain alignment of the sun, Earth and moon, astronomers are able to calculate when the next one occurs. In 2014, lunar eclipses take place on April 15 and October 8.

    What is the meaning of a yellow moon?

    A:

    When the moon appears orange or yellow, it simply means that the observer is looking at it through more layers of atmosphere. Similar to the way in which the sun will look orange or red on the horizon, when the moon is low in the sky, the light from it will have to pass through more of the blue-absorbing atmosphere to reach the viewer's eye. By this time, only yellow, orange and red light will remain unabsorbed.

    The moon gets its light from the sun, the same source as Earth and other planets. The location of the moon along its orbit affects the amount of light it receives from the sun, leading to the different phases of the moon.

    Does the moon reflect light from the sun?

    A:

    The moon does reflect light from the sun, which is why it is visible in the night sky. The actual surface of the moon is mostly a dark grey color, reported by astronauts who have walked on it, but it appears a bright yellow or white in the sky due to the reflected light.
