You may not believe that the moon we often see has eight colors. Let's take a look at the different colors of the moon.
The moon itself is dark gray, because the surface of the moon is covered with dust composed of minerals such as coal, iron, calcium, and aluminum, which are basically dark gray when they are in a dusty state. So what about the other seven colors? This is because the moon itself is not luminous. The moon we see is a reflected ray of sunlight. Sunlight has seven colors: red, orange, yellow, green, cyan, blue, and purple, and will reflect different colors in different situations. Most of the time, the color of the moon we see is yellow, the hour does not recognize the moon, and it is suddenly a white jade plate. In the ancient poetry articles of our country, most of them will describe the moon as white. This is because in a clear state, there are fewer dust and water vapor particles in the air, and the seven colors of sunlight can penetrate the atmosphere, and they are mixed together to appear white. The above two cases are actually relatively common, but the following situations are relatively rare.
The red moon, also known as blood, generally only appears during a total lunar eclipse. At this time, although no sunlight directly hits the moon, the Earth's atmosphere will absorb all other light colors, leaving only the longest wavelength of red light refracted to the moon. At this time, the moon is observed on Earth to appear red. When a total lunar eclipse appears, the thinner the clouds, the higher and brighter the moon's redness, and occasionally it will take on an orange-yellow appearance. This is because when the moonlight shoes wear the atmosphere to reach the horizon nearby, the light will go a longer distance, and the cool light will be absorbed or scattered more, so the moon will appear orange-yellow when it is on the horizon, and sometimes the moon will also appear pink, this pink moon is also called a supermoon, is a new moon or full moon, the moon is located near the perigee phenomenon, at this time we see the variables will be larger and brighter than usual.
Supposedly, this month will appear four to six times a year, which is not uncommon in theory, but the pink moon in the narrow sense refers to the full moon that appears pink, it can only appear in a specific area, and it needs to be just right for factors such as cloud layers and atmospheric conditions, so this phenomenon can not be sought. Blue moon is not just a toiletry, it is also a natural phenomenon. Blue moons in the narrow sense are rare, such as volcanic eruptions, where large amounts of ash are ejected into the atmosphere, and the dispersed ash can distract the red light in the moonlight, which means that the moon will appear blue or green. This will continue for a long time. In ancient times, people did not understand rumors, and encountering such a situation foreshadowed a disaster as an ominous sign. Fortunately, this phenomenon is very rare, and it is rare in a hundred years. So people don't have to worry all the time, this variable is the rarest moon color that humans know at present, and it is also the most noble color of the moon, because in the vast universe, purple represents life.
As for why purple moons are rare, this is due to the shortest wavelength of the seven colors of the sun, purple, and only when the other seven colors in the sunlight are scattered or refracted, will the purple moon appear. These are the different colors that humans know about the moon. Of course, in theory, according to the different conditions of the environment, the moon can actually show countless colors, but it is difficult for humans to observe. And what color of the moon is your favorite color?
