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.

Halloween and the full moon

In 2020 the full moon will fall on a 31st October and a Halloween party can take place in the full moon light. The imagination of people fits this well apparently, because no matter where you look, the full moon can be seen in all portrayals of Halloween. In historical terms, there is no connection, however. Halloween is the evening before All Saints’ Day (originally: »All Hallows’ Eve«). The basic idea of this festival is the remembrance of saints and it is connected to the wish to drive out bad spirits. This is how the gruesome costumes came into play.

The full moon at daytime

One obviously has the night sky before one’s eyes when thinking of the full moon. In reality, however, the event »full moon« has nothing to do with the fact whether it is night or day for us. The full moon occurs when Sun – Earth – Moon form a line in space and exactly in this order. The Earth lies in fact between the Sun and the Moon. Depending on what time this happens, it is night on the hemisphere that is turned away from the Sun and you can see the Moon in the sky. But on the hemisphere that is turned towards the sun it is daytime at this point and the full moon cannot be seen, because when observed from this position it is actually behind the Earth.

The Roman Lunula Amulet

lunula-amulet_198x198

In the Ancient Roman Empire, lunula amulets were often worn as a lucky charm, but also as protection against evil forces and demons. Special crescent-shaped jewelry pieces were made for girls, to grant them the protection of the goddess Diana. Diana is the goddess of the Moon and also of hunting in Roman mythology. Artemis is the equivalent among the Greek Gods.

The origin of the Moon

The Moon has not always been there. And although, no one has been present to observe its creation, scientists today, largely share the view that our Moon originates from a collision between Earth and another planet 4.5 billion years ago.

Our Earth – that looked completely different to how we know it to be today – had been circling with the planet Theia, which was about the size of our Mars, around the Sun. Some day, these two orbs clashed, produced an inconceivably powerful collision that totally destroyed Theia and catapulted an enormous amount of rocks into the orbit of Earth.

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.

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:

»Moondance« by Van Morrison

moondance_198x198

It is time again to write about a song on the theme of the Moon: »Moondance« by Van Morrison. Released in February of 1970, on the album with the same title, by the musician from Northern Ireland, belongs to the classics amongst the moon songs. It hovers stylistically between rhythm & blues and country rock, but also jazz influences can be recognized. »Moondance« was placed in the English and American Charts. It was never a smash hit, but still today belongs to the concert repertoire of ›Van the Man‹ and can be heard time and again on the radio.

The Chinese moon goddess Chang’e

chang-e_198x198

Chang’e is the Chinese moon goddess. She does not symbolically represent the Moon, like for example the Greek moon goddess Selene, but Chang’e lives on the Moon and is befriended with the well-known rabbit that is very familiar to us. But has she always been up there?

The legend says that she got there some thousand years ago. There are different versions of the story, which we don’t want to elaborate on. In any case, her husband Hou Yi plays a central role, who came to help because of his skillfulness in archery, when ten suns threatened to burn the Earth and he shot down nine from the sky.

Dance at the full moon in »The Lion King«

»The Lion King« from 1994, is one of the most successful animated movies, and just like in other works from the house of Walt Disney (»The Lady and the Tramp« and others), we are able to gaze at the full moon up in the sky in nightly scenes.

Particularly well-known is the image, where Simba dances across a tree trunk with his companions, which enables them to cross a large river in front of the backdrop of a gigantic full moon. This motif has also been used for various movie posters and can also be watched in the movie trailer:

The shooting star night of the Perseids

Who doesn’t enjoy seeing a shooting star in the night sky? It is said that a wish is granted, which is believed to come true if kept secret and not shared with anyone. And who doesn’t want our wishes to become a reality?

To put it in physical terms, a shooting star is a »meteor«, a luminous effect, which develops with the occurrence of a »meteoroid« (a more or less large lump of rock from space), which burns up in the earth’s atmosphere. Not to be mistaken, however, with a »meteorite«. A meteoroid is only called like that, if it hits the earth’s surface (and could actually cause immense damage). So, no need to be concerned: shooting stars are harmless and very beautiful to watch.
