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.

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.

“Tsukimi”: Moon-viewing in Japan

japan_198x198

Japan has a custom, which is called “Tsukimi” or also “Otsukimi” that literally means “moon-viewing” (tsuki = jap. Moon). This tradition dates back to the Heian period (794–1192) where Japanese culture and the arts were refined to a high degree. At that time, elements of the Chinese “Mid-Autumn Moon Festival” were introduced in Japan, and festivals and rituals were held in the eighth sun month (which corresponds to September in our current calendar).

»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.

Children of the full moon

We would like to take a quick look at people who were born at the full moon. As to this, we remind you, contrary to widely spread opinion, that there are not more children being born at the full moon than at any other point in time during the lunar phases. Extensive studies over many decades have arrived at this result. Even though, many people may perceive or experience this differently – the numbers are unmistakably clear. We have already written an article about this »More births at full moon?«. So there are as many full moon children as there are new moon children etc.

“Full Moon Song” by Peter Bradley Adams

Peter Bradley Adams is an American singer-songwriter, who has managed amid the flood of commercial songs and loud beats, to tell his own story – with a warm voice and quiet sounds.

His song “Full Moon Song” from 2011 is one of those stories.  According to his own statement, this song came to fruition after a short stay in prison (from which he did not break out as stated in the lyrics, but was released on bail). He talks about freedom that now becomes significant to him and makes a new life possible. He wants to see the world through the eyes of a child and experience love without fear of losing something.

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 song »Fly Me To The Moon«

frank-sinatra_198x198

The jazz classic »Fly Me To The Moon«, originally written by Bart Howard in 1954, gained worldwide fame through Frank Sinatra (1915–1998). His version from 1964 accompanied the space mission Apollo 10 to the Moon in May of 1969, and was played when the spaceship orbited the Moon. Further, it was the first song ever that was played on the Moon, when Buzz Aldrin stepped onto the Moon with a portable cassette player during the Apollo 11 mission in July 1969.

Jules Verne’s journeys to the Moon

It is fascinating how the French writer Jules Verne (1828–1905) envisaged the journey to the Moon 100 years in advance in his science fiction novels and was able to put it into words. Admittedly, he was quite taken with describing journeys to unimaginable places: from the deep sea (“20,000 Leagues Under the Sea”), via the circumnavigation of the Earth (“Around the World in 80 Days”) through to the interior of the Earth (“Journey to the Center of the Earth”). Of course, space had to be part of this and this is how Jules Verne firstly wrote the novel “From the Earth to the Moon” (»De la Terre à la Lune«, 1865) and then later the sequel “Around the Moon” (»Autour de la Lune«, 1870).

The Moon illusion

Have you ever wondered, after you took a photograph of the full moon that the Moon looks much smaller on the picture than as it appears to you in real? This effect occurs particularly when the Moon is above the horizon. This is a so-called Moon illusion, which is an optical illusion, meaning it can only be seen this way through our perception and is therefore not depicted on the photograph.

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.
