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:

To the hairdresser at the full moon?

You always hear that certain things should be done or left undone at certain phases of the lunar cycle, also during a full moon. You can believe it or not. It surely cannot be proven and to be honest, we are quite skeptical with regards to the attribution of human activities and lunar events. However, we would not like to exclude it – after all neither the efficacy nor the inefficacy of such theses has been proven. As long as you don’t get caught in your own convictions, it is part of people’s liberty to create their lives freely.

What has the full moon got to do with Easter?

Quite a lot! The date of Easter is actually determined by the full moon. Quite contrary to Christmas, the Easter date is part of the changing holidays and defined as follows: “Easter is on the Sunday after the first full moon in spring.”

At first glance, this appears to be quite easy: one look at the calendar, beginning of spring is mostly on 21st March and then simply search for the next full moon and the weekend after will be Easter.

The Greek moon goddess Selene

Selene is the Greek moon goddess, she is a daughter of Hyperion and Theia from the Titans, a race of deities. The two siblings of Selene are Eos (the goddess of dawn) and Helios (the god of the sun). These three, forge the bridge between day and night, the Sun and the Moon, masculine and feminine. Later, in Greek mythology, Selene has also been equated with Artemis, just like Apollo is linked with the sun god Helios.

The GRAIL twin moon probes

A probe is an unmanned flying object, which explores space. Different to a satellite, a probe does not circle the Earth but flies to other celestial bodies, which they circle, too, but are then called orbiters. Two of these probes have been on the way to the Moon since 10th September 2011, to take measurements with unprecedented accuracy. The GRAIL lunar probes have reached the orbit of the Moon as planned, at the turn of the year 2011/12 and are now currently at work, until they will shatter on the Moon’s surface. In the meantime, they will have transmitted lots of data back to Earth.

“Moonrise, New Mexico” by Ansel Adams

Ansel Adams (1902–1984) was one of the most influential photographers in the US, who particularly became famous for his magnificent black and white photography of American landscapes and national parks. He is the role model of many photographers  and set standards with his shots. And as chance would have it, one of his most renowned photographs is an image with the rising Moon in New Mexico.

Full moon delicacies

Today, we would like to focus on a more culinary subject of everything that can be eaten or drunk and is prepared in connection with the full moon. Apparently, there is a multitude of vendors (especially in Switzerland), who regularly manufacture their products at the full moon and who detect that the quality of their foods differs from the foods, which have not been produced in connection with any lunar happenings. These products appear to sell accordingly and successfully. We have not been able to fathom out whether this is really related to the Moon – it might also be that the consciousness of the acting persons is different, or that the customers bring along the appropriate willingness to appreciate the reference to the 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.

No terminator on the full moon!

No, this is not about another sequel of the science fiction movie or whether Arnold Schwarzengger is planning a trip to the moon … It is more about an astronomical term, where »terminator« describes the day-night border of a celestial body. This is the visible border between the illuminated side and the dark side of the object, being the border between day and night on the celestial body. The word »terminator« derives from Latin »terminare« = conclude, restrict.

Why corals adore the full moon

Although, one could easily presume that full moon influences the reproduction of many creatures, this has really only been proven for some species. One assumes this is the case with wolves, specific insects or crabs and also many humans vow not being able to do anything other than to look for the closeness of the other (or the same) sex at full moon. But absolutely certain are scientist only about one animal species that may not even be considered an animal by many: the corals. Here it has been established that reproduction is dependent on water temperature and moon light.

Mooning – displaying the bare buttocks

The human buttocks are being linked to the Moon at times, just like in the case of the so-called sexual position “full moon”. This is due to the large, round shape of the buttock cheeks, which could occasionally remind of the lunar globe when properly lit or observed from the correct angle.

If someone shows their bum publicly, he or she usually does so to break a socially accepted norm and to express their protest or contempt. Or simply because of the fun of it provoking other people. This “baring the behind” is called “mooning”. It derives from the verb “to moon”, which means  “to expose to the (moon)light”.
