Phases of the Moon

In general, the month during a cycle of revolution, ie over a period of 30 days undergoes several phases. What is meant by the phase of the moon itself is a form of moon that changes when viewed from the earth. This phase depends on the position of the moon against the sun when viewed drai earth. The position of the moon against the sun and also the earth itself is divided into three positions, namely:

In this conjugation, the position of the moon in the direction of the sun. At that moment the part of the moon facing the earth is dark or invisible. In this aspect of conjugation can occur solar eclipse because sunlight that leads to the earth obstructed by the moon, so that we can not see the moon to be luminous.

That is some position or position of the moon that occurs during one period of the lunar revolution. There are still other phases of the moon, including the crescent moon phase or crescent and also the lunar or gibbous moon phase. Thus within a synodic month, successive lunar phases change as follows: new moon - crescent moon - early child - convex - full - convex - ending - crescent moon. Thus there are five phases of the month that occur in one period of the month or month one month revolution, namely:

1. New month or new moon
2. The first crescent moon or waxing crescent
3. The first quarter or first quarter
4. Full moon or full moon
5. The third quarter or third quarter

The moon we see at night, which is also a source of natural light at night sometimes looks strange and different in every time. This month why it can seem strange because every month this month has a certain kind of phase of a particular month. However this month evolved around the earth takes about 30 days, therefore the phase phases of the moon are visible from different shapes and also this color can not be separated from its different positions in each month, and also because of different jarank. This is also because we as humans who occupy only one point of the region that is on earth so sometimes we find this month is at a different distance.

The moon as Earth satellites that are visible glowing at night also sometimes experience one unique condition. Some of the conditions experienced by the moon that occurs at certain times include lunar eclipse, super moon, and also blood moon. The lunar eclipse itself is a rare event in a region. The lunar eclipse is an event where the moon looks like it disappears and then reappears in a few minutes later. While the super moon is an event where the moon looks very large because at that moment the moon's position is very close to the earth, so the moon will look bigger many times in certain regions of the earth. While the blood moon is an event where the moon will appear red, so it looks amazing as well as horrible. The color of the red moon is what causes this event called blood moon which means the blood of the moon.
