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.

Ice-cold legends

When taking a look at the Inuit [*] in the far north, you will find astonishing myths about the full moon. The Inuit live along the Arctic Ocean from the north east of Russia to Greenland and Canada, where coldness reigns. The culture is imprinted by an archaic consciousness, life is interwoven with legends that were never written down, due to harsh living conditions, but only passed down by word of mouth.

The moon inside the word »Monday«

In many languages, inside the word for the weekday »Monday« you find the word »moon«, sometimes slightly modified but mostly easily recognised. This does not appear to be a coincidence. But why? Surely, the Moon cannot only be seen on Mondays and no other good reasons comes to mind quickly why a specific day of the weekly cycle should be connected to the Moon.

»It was dark, the moon was shining bright« – a German poem

old-book_198x198

There is a German poem called »Dunkel war’s, der Mond schien helle«, in which the first line has been dedicated to the Moon and which boasts special features. For one thing, nobody knows who wrote the poem, which is quite unusual coming from the »land of poets and thinkers«. For another thing, it is based on the principle of the »oxymoron«. This is a figure of speech that juxtaposes elements that are contradictory or that are created from terms which are mutually exclusive. Straight away, the first line reveals this principle, because it cannot be »dark«, when the Moon is shining »bright«.

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.

Lunar lava tubes

lava-cave-moon_198x198

When inviscid lava flows out of the volcano, it is possible that cavities are created inside the conduits, due to the different speeds of flow and temperatures. It is like a roof being formed above the flow of lava, which continues to flow inside. After cooling of the rocks, tubular cavities remain.

This phenomenon exists on Earth when volcanoes erupt, and scientists assume that those tubes and cavities could also be  prevalent on the Moon, dating from a time when vulcanoes were still active there. The lesser gravity benefited the formation of the tubes and might have also contributed to the fact that there could be kilometer-sized cavities underneath the Moon’s surface.

»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 heartbeat of the full moon

We have compared the amount of visitors from our full moon pages with the curve of an electrocardiogram (ECG) and came across an astonishing similarity. It almost appears as if the attention that we humans give to full moon would have its own heartbeat …

It is obvious that the interest in full moon can be linked to its rhythm. The average duration of a moon month is approx. 29.5 days, so a little bit more than four weeks and a little bit less than one calendar month. One can safely say, a lot of people are paying attention to the moon at full moon and clearly a lot less so during the other moon phases.

The Moon Festival in China

In China, the September full moon is a special day. It is the day of the Moon Festival or Mid-Autumn Festival. This festival is traditionally celebrated on the 15th day of the eighth month of the old Chinese calendar. Because the moon month averages 29.5 days in length, the 15th day is usually a full moon day, however, there are slight shifts in some years. The Moon Festival is one of the most important festivals in China, but is also held in Korea and Vietnam as well as in the respective districts in big cities around the globe.

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.
