When do you call a full moon “blue moon”?

Everyone knows that about once a month is full moon … but, strangely enough, a full moon is always on a different day each month and always at a different time. The reason is that the moon month is shorter on the average, than the calendar month. Without being to mathematical, one can say that a moon cycle lasts approx. 29.5 days. This is how the time of full moon spreads irregularly throughout the calender months and it happens (about every 2.5 years) that two full moon dates fall onto the same month, one at the beginning and one at the end of the month. This second full moon is called a “blue moon” today.

»The Woman of the Apocalypse« and the Moon

woman-of-the-apocalypse_198x198

»The Woman of the Apocalypse« is a depiction of a Virgin Mary that is surrounded by sunrays (hence she is also called sun-crowned Madonna), and shows a moon crescent underneath her feet. Quite often stars can also be seen around her head. This portrait goes back to the biblical text »The Woman and the Dragon« in the Revelation of John, chapter 12. This describes the fight of heaven against the red dragon that embodies the evil in the world.

The »Void Of Course« Moon (VOC)

void-of-course-moon_198x198

The terminology »void of course« Moon (VOC), refers to a specific duration of time in astrology, during the Moon’s passage through the signs of the zodiac. To this, the basic conditions are created by the so called »aspects« of the Moon, which refers to its connection to other planets in the sky. For example, when the Moon and another planet are opposite to each other, it is called »opposition«. Further important aspects are »conjunctions« (next to each other), »square« (angular distance 90°), »trine« (120°) and »sextile« (60°). So when the Moon passes through a zodiac, various of these aspects surface. After approximately 2.5 days, the Moon changes into the next zodiacal sign, to create new aspects again. The phase between the last aspect in the current zodiac and the transition to the next zodiac is called »void of course / VOC«. The length of this void of course can take anything from two minutes up to two days.

The biblical Moon

moon-bible_198x198

We have already searched and found the word »full moon« in the Bible, but only in two places in the Old Testament (Psalm 81:3–4 and Proverb 7:18–20). This is surprising, because the Last Supper of Jesus and his disciples must have taken place during the full moon, and hence, should have been mentioned in the New Testament.

We have extended our research and have looked for the word »moon« in the Bible. Here too, most passages can be found in the Prophetic books and Psalms of the Old Testament. However, there are also two places in the New Testament in the Gospel of Luke and Mark.

Is the Moon round?

moon-orange_198x198When looking up to the full moon, you see a sphere and there is no doubt: the Moon has to be round. And we assume quite simply that a sphere is orbiting our Earth. This is correct indeed, if taking a lax approach in the definition of a sphere. The Moon is spherical, but differs considerably from the perfect shape. On the one hand it is flattened at the North Pole and South Pole, and on the other hand, its reverse side, which is turned away from the Earth, is convexed outwardly.

The spacesuit

spacesuit_198x198

When examining it thoroughly, we humans will never be able to touch the Moon directly, because even when an astronaut is standing on its surface, there is always the glove of the spacesuit in between, without which, life could not exist on foreign celestial bodies (consider also Mars).

There are a variety of dangers that the spacesuit protects the wearer from: vacuum, cold and heat, weightlessness, micrometeorites and radiation. Hereby, a distinction is made between suits that are only worn inside the space capsule during specific maneuvers, and suits that are used for space walks and actually leave the spacecraft.

Chinese moon landing in sight

After USA and the Soviet Union, China will be the third nation in the world travelling to the Moon with their space program, and they will probably land there with the astronauts as well in the long term. At the moment, an unmanned spaceship »Chang’e-3« (moon fairy) is on its way to the Moon since 1st December 2013, planning to land in the Mare Ibrium on 14th December and supposed to transport a rover for research purposes of the Moon’s surface. The vehicle is called »Yutu« (jade rabbit).

Moon rock

Our Moon consists of rock, which was formed newly during its creation through a collision between the Earth and another planet, around 4.5 billion years ago. Lunar maria were created through meteoroid impacts, which can be seen as dark spots if observed from Earth.

A small amount of these rocks are on Earth. One part stems from a variety of moon missions (Apollo and Luna), the other from meteorites that struck the Earth as fragments.  If you add up the registered mass of these rocks, you’ll end up with 738 kg (1,627 pounds). Which is actually »just a grain of rice« in comparison to the 81,000,000,000,000 kg that our Moon weighs.

The full moon and Marc Chagall

There are probably few painters who made use of the full moon in their paintings as often as Marc Chagall (1887–1985), the French artist of Russian-Jewish descent, who was regarded as »le poète« (the poet) amongst painters, due to his symbolic shapes and colors.
Chagall lived for almost a century and if one can classify his style at all, then it would have to be expressionism. He worked in Russia, France (primarily Paris) and in the US (primarily New York) and was on an inner and outer journey throughout his life.
