The full moon knowledge

Here we begin our little journey to the full moon. A few words about the fascinating quest of the greater purpose, that includes the full moon circulating through our lives. In layman’s terms and not always scientific (astronomy experts – don’t look too closely!). We would like to wish you illuminating moments. Enjoy!

How do you define a full moon?

A full moon is when the Sun and the Moon are facing opposite, being in opposite direction from an Earth perspective.

This might feel astonishing if one imagines that the Moon is on one side, the Sun on the other and the Earth in between? Shouldn’t the Earth throw a shadow onto the Moon? Bingo – this is exactly what she does! But only when the Moon is exactly on the Earth orbit, the so called “ecliptic”. When this takes place, we speak of a lunar eclipse!

How long is the interval between two full moons?

The Moon needs 27.33 days to circle around the Earth. Something that is also referred to as “sidereal time”. But because the Earth orbits the Sun, just like the Moon orbits the Earth, the Moon has to travel two further days in order to resume the same position to the Earth and Sun. This is then called the “sidereal time”. In order to determine the point of time of the reoccurring full moon, the sidereal time serves as basis.

When is full moon in Europe, Asia or America?

The answer is: “everywhere at the same time”. This refers to the so called Universal Time (UT) though, which is used for general astronomical events. We have already learnt that full moon is an astronomical event, where the moon, sun and the earth play a role by being in a specific position. So, full moon takes place at a specific time in the outer space. This point of time is specified by astronomers namely by the Universal Time.

How long is the full moon?

There are multiple ways of approaching this question. If we look at it from a purely theoretical standpoint, we might be tempted to say that the full moon is infinitely short, since the phases of the moon are changing continuously. The moon is not yet quite full shortly before the full moon, and is already waning shortly afterwards.

However, there is a practical aspect that lets us quantify the full moon as a finite and measurable span of time: Since the Sun is significantly bigger than the Moon, its rays are able to reach just a little over half of the Moon’s surface. This means that the timespan in which the visible side of the Moon’s surface is irradiated (as seen from Earth) is longer than infinitely short.

And is it all the full moon’s fault?

Whether scientists, astrologers or esoterics, they agree on one thing: the moon influences earth and life on earth. For instance, it regulates the tides through its magnetism. Also continents feel the consequence of this magnetism and either raise or lower their position sometimes up to 26 cm.

Sex and the full moon?

In nature it is a known fact: for some animal species, mating takes place at full moon. However, the examples that can be found on this subject are rather simple. Full moon serves in some cases indirectly as the cause (for instance through the high water levels during the tides that the horseshoe crab uses to deposit its eggs) or also as the signal for both sexes of a species to begin at the exact same time to safeguard their future existence (a particular type of fly or also corals). It is understood that also wolves are led by full moon when it is time to mate.

It is said …

… that people are looking for an argument at full moon or are especially happy …

… that if full moon is surrounded by a haze, a person dies …

… that you raise your hat three times to the moon (being a man) or you make a curtsey (being a woman), in order to protect yourself from misfortune until the next full moon …

… that whoever does not chink glasses with full moon at least once, does not deserve any happiness [Greek toast] …

Information about a lunar eclipse

Easily explained

During a lunar eclipse, the Moon moves through the shadow of the Earth. Which means, that the Earth is positioned quite exactly between the Sun and Moon and casts its shadow onto the Moon. This is only possible at full moon and if some other requirements are met. Depending on whether the moon passes the partial or the core shadow of the Earth, we speak of a partial or total lunar eclipse.

Charlie Chaplin and the full moon 

Sir Charles Spencer Chaplin (1889–1977) is considered one of the first movie stars ever and made film history with his acting and his works. He is also one of the few artists who managed the transition from silent films to sound films.

Because of using archetypal imagery and symbols in his films, it is natural that the moon could also play a part somewhere. We found four references:

Nena and the full moon

Nena and her band belong to the most successful artists in German music history. With »99 Luftballons« from 1983, she made a name for herself internationally and also reached 2nd place in the US charts with the English version »99 red balloons« [*]. This has only been accomplished by very few German musicians.

In the song »Vollmond« [full moon], also from 1983, Nena sings about the silver Moon and describes the romantic longing and restlessness, which can capture us during a full moon:

“Lunatic” – the crazy side of the moon

As already mentioned in our article about sleepwalking, a connection was made in the past between the moonlight and people, if their conduct was odd, crazy or threatening. One assumed that the moonlight caused this behaviour and spoke of “lunatic”, which derives from the Latin “lunatus” and means more or less “influenced by the moon”. In English, this terminology “lunatic” has been used for many forms of mental illnesses over many centuries. Because many of these disorders could not be explained for a long time (and there are still plenty of questions today), one was in need of a point of reference, a word that would accompany on the path of darkness. The Moon was very convenient.

The Moon on banknotes

10-franken-moon_198x198

We have been pondering about, whether a banknote does exist with a depiction of the Moon. Thanks to Google, we found something and discovered a variety of examples from different countries – with popular and less well known currencies. On the left you can see a detail of a Swiss 10 francs note, which depicts our solar system with several planets, amongst them also our Earth and its Moon.

The mooncalf

mooncalf_198x198

The word »mooncalf« is connected to a sad story, because in earlier centuries it was used for calves that were born malformed. It was assumed that the Moon was responsible for this, which was generally seen as a symbol of the feminine and dark side of life. Not exactly fair toward the Moon and unfortunately characteristic for the attitude wanting to assign the good to the masculine and the evil to the feminine.

Is the moonlight white or blue?

As is generally known, the moonlight is actually sunlight reflecting from the surface of the Moon and reaching us here on Earth. You ask yourself the question, whether the moonlight may have a different colour than the sunlight, especially since a nightly scenery usually appears to be bluish. Also movie scenes, are portrayed in blue and so are many pictures and photographs. We would like to forestall the answer: the moonlight is nearly white. The night appears blue due to other reasons.

»Fishing Party« by Fitz Hugh Lane

Inspired by his trip to the coast of Maine, USA, the American artist and lithographer Fitz Hugh Lane (1804–1865) – aka Fitz Henry Lane – created the full moon painting »Fishing Party«, in 1855. He was a representative of the American luminism, a painting style characterized by a specific form of light-flooded landscapes in the 19th century (lumen = lat. light).

The magic of vintage moonshine cards

It was about 100 years ago when a special kind of postcard was fashionable in Europe: the moonshine card. This is a kind of postcard with motifs of cities or landscapes that was to convey the effect of a nightly moonshine scenery. It was supposed to be romantic and this obviously appealed to people in those days. There were printed cards as well as photo-postcards that were »dipped into moonlight« in this way.

A lunar base via 3D printer

A 3D Printer is a device with which you can print three-dimensional objects. This may initially sound strange, but will become obvious once you know that the objects can be built in layers. The printer applies the relevant materials instead of ink (i.e. plastic) and consequently forms the result.

Because these printers are now available for consumers at normal prices, in the future, we will purchase merely printing data instead of the product. So this trend actually moves away from mass-market productions and towards individualized items.

Hasselblad cameras on the Moon

hasselblad_198x198

The medium-format cameras by the Swedish manufacturer Hasselblad, enjoy a legendary reputation and were – at least back then – probably the best cameras in the world. Not surprising that NASA chose exactly this brand during their equipment selection for their Moon missions. At that time, everything revolved around photographic quality of taking the pictures and moreso, around the reliability of the cameras. Back then, you did not have the opportunity to immediately examine whether a photograph turned out well, because all material could be developed only after the return to Earth. So, with regards to cameras there was the need to hedge one’s bets – inconceivable, if those photos would have turned out a complete flop.

Between scepticism and mysticism

There is a wide spectrum of views and opinions about how the moon may influence human life and it is in the very nature of things, that these opinions lead to discussions. During the course of the years, we got acquainted with many different viewpoints and are trying to give room to these diversities on these pages.

Let’s imagine two people for example, a sceptic, who analyses sensibly and critically, and a mystic who allows his actions to be guided by faith and dedication. Let’s have both people answer the question, whether principally, full moon has an effect on human beings.
