Moon Phases

When you look out at the moon, you might notice that what you see isn't a circle but an oval, or an half-circle, maybe just a big black hole. These are moon phases, we see these different parts because we can't see the entire moon. This is caused by the shape of the moon, since it's an sphere, the sun will always light upon the moon only 50% at a time, except during an eclipse. What we see are different parts of the lighted part of the moon.

Waxing means it's getting bigger in appearance and waning means it's getting smaller in appearance.

Remember, the moon isn't making it's own light but is reflecting light off from the sun and on to the Earth. The angle we look at the moon at will reflect different amounts of light at us.
