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:

“Sleepless in Seattle” – without the full moon?

Who doesn’t know this movie, a classic amongst romantic comedies? Shot in 1993, with Tom Hanks as the architect Sam Baldwin and Meg Ryan as the journalist Annie Reed, who do not know each other but are still able to find one another thanks to Sam’s son Jonah, who recognizes that Sam and Annie belong together and for that, he leaves no stone unturned.

On the movie poster, you can see the full moon, just above Meg Ryan and we watched this movie for the 137th time to find out whether the full moon is also visible during the movie  – wrong! Neither in the scene where Sam talks to the psychologist on the radio for the first time, while Annie listens in the car, nor in the closing scene in New York, and on the Empire State Building we can see the moonlight shining, although this would have certainly been a gain. Also with reference to the title and the addressed topic of sleeplessness, this would have been an obvious approach.

Full moon above Swan Lake

We recently went to a ballet performance – Swan Lake by Tschaikowsky – with the Moscow Ballet. Immediately, after the curtain rose for the first time, the stage set showed a nighttime scenery, with a castle at a lake and high in the sky a wonderful full moon. Later, when the »swans« appeared and everything was bathed in a bluish light, the entire room was  permeated with a fantastic and subtle atmosphere.

The dancers were sensational. Every movement danced with absolute emotional power and perfect precision. We were amazed and in awe. A true delight for the senses …

In the finale, the castle scenery came into action again and the entire performance was surrounded by full moon light.

Whether Tschaikowsky had the full moon in mind?

Shakespeare and the full moon

We figured it would be obvious to look for the full moon in the works of England’s most famous poet William Shakespeare (1564–1616). Surprisingly, the »moon« is to be found more often, however the word »full moon« appears in the original text only once, namely in »King Lear«.

The text of the comedy »A Midsummer Night’s Dream« (approx. 1595), contains the moon a whopping 52 times (28 times in the last act alone) and it can be assumed that Shakespeare was thinking of the full moon when he wrote these lines. Although it is not described as the »full moon«.

Let’s go

Let’s begin the New Year 2011 with the opening of the full moon blog. A true innovation to the full moon pages.

For everyone, who is not quite sure what a blog is, let’s say it is a kind of an Internet diary. The word »blog« is an abbreviation of »weblog«, which again derives from »web« (for Internet) and »logbook«, a term used in maritime shipping for recording daily events. Interestingly enough, it is mentioned in WIKIPEDIA that logbooks are of great importance in legal cases involving maritime commercial disputes, and therefore mandatory to be kept and not on a voluntary basis. As blogger (name of someone who writes in a blog), we certainly would not keep this rule, but encourage spontaneous participation and think it should be fun, and whenever possible, we will establish a connection to the full moon.

The full moon in opera

Let us still stay with the music for a little while and let us bring our attention to a grand musical genre of theatre, the opera. We recently saw TOSCA (from Puccini) in Madrid and lo and behold! In the first act, we suddenly heard »luna piena«, which is Italian for full moon. A real highlight!

Then we had the idea to rummage through some libretti (opera lyrics) to find out if the full moon motif may also play a part in other operas. For this purpose, one can view the libretti online. We were interested in particular in the actual mentioning of it, as these were created by the composers themselves, whereas the appearance of the full moon on stage was usually the part of the stage designer.

Moon boots

moon-boots_198x198

Who does not know the »moon boots« – these bulky snow boots, which appeared in the 70’s and 80’s and have taken their claim ever since in the winterly fashion scene. The Italian Giancarlo Zanatta designed the shoes, inspired by the moon landing in 1969. Astronauts Neil Armstrong and Buzz Aldrin wore overshoes with wide soles, which provided the formal inspiration for moon boots. Zanatta took immediate care of the production of the shoes with his company called Tecnica, which is run by his son Alberto Zanatta today, and still sells up to 700,000 pair per year.

Adam Elsheimer paints the Moon like no one before

More than 400 years ago, the German artist Adam Elsheimer (1578–1610) painted the picture »Flight into Egypt« (1609), where he depicted the well-known biblical scene of the escape of Joseph and Maria with the Christ Child. The special feature of this painting is, that it shows the full moon and night sky with such a richness of detail on a scale not seen before. Scientists – like for example Dr. Christian Sicka of the ›Deutsche Museum‹ Munich – have examined this work and come to the conclusion that this is possibly the first correct astronomical true to life depiction of the night sky in paintings. One can easily recognise the lunar maria on the Moon’s surface and also the Milky Way, moreover a clear graduation of brightness with the individual stars.

Waxing or waning?

This is about how to differentiate the waxing moon from the waning moon in the sky. »Waxing« is known to be the lunar phase between the new moon and the full moon (meaning the time when the crescent increases in size), whereas »waning« is known to be the lunar phase between the full moon and the new moon (the time when the crescent decreases in size). In order to remember on which side the curve is, here are some neat mnemonics.

Luna 2 – the first space probe on the Moon

luna2_198x198

Luna 2 was a Soviet space probe that impacted the Moon on  13th/14th September 1959. Space probes are unmanned flying objects that are used for exploration. In this case, it was about exploring the Moon, with the goal to fly a human to the Moon and have them return safely. History shows that this did not become possible until ten years later, with the moon landing of Neil Armstrong within the framework of the Apollo 11 mission, in July 1969.
