Astrology of the 13 Signs of the Zodiac Ophiuchus:
The New Sign of the Zodiac Circle
By Vasilis Kanatas



We have all seen horoscopes of traditional astrology fall woefully short. Most of them will say ten different things in order to get one right. Yet, is it possible that astrology itself isn’t inaccurate? Could astrologers be using wrong zodiac sign, the wrong planets and the wrong ascendants?
Physicist Vasilis Kanatas, author of the new book Astrology of the 13 Signs of the Zodiac Ophiuchus: The New Sign of the Zodiac Circle, says there is a way to put astrological predictions on a solid footing by creating a more valid foundation for astrology using the discoveries of astronomy and by introducing a new zodiac constellation.
“Today’s astrology has outlived its lifetime and its elements have been rendered obsolete by its cousin, the science of astronomy,” says Kanatas. “My work takes into account all available modern scientific information regarding the current actual positions of the 13 Zodiac constellations – the 12 old signs plus Ophiuchus.”
Astrology of the 13 Signs of the Zodiac proves that a very tiny annual movement of the axis of the Earth called “Precession of the Equinoxes” prompts corresponding discrepancies in the predictions of astrology, which move further and further away from reality with each passing year. That same inaccuracy with regard to position applies not only to the other planets of our solar system, but also to the sun and moon. By extension, the constellations of Zodiac are also in different positions from those assigned to them by Western Astrology, and a new zodiac constellation, Ophiuchus has been identified in the path of the Sun on the ecliptic. With this shift also comes a change to most people’s zodiac sign and a corresponding much more accurate horoscope.
Astrology of the 13 Signs of the Zodiac, firmly grounded in the sciences, recognizes the influence that the planets have over our lives and examines:

The fundamentals of Astrology: Past to Present
Equatorial movement and its discrepancies in the predictions of Astrology
Ophiuchus and the new Zodiac
What the changing of your Zodiac sign indicates
The vital importance of the Sun, the Moon and Astrology’s new variable: Sunspots
Construction of a horoscope under the 13 signs of the Zodiac
By marrying together only those elements of the past that can be supported by today’s science, Astrology of the 13 Signs of the Zodiac looks beyond the quaint notions of the past to help people learn to live with a new connection of astrology and astronomy.

Vasilis Kanatas was born in Amfissa, part of the Municipality of Delphi. He is a physicist and wrote his dissertation in Astronomy & Uranography entitled: "Concerning Constellations". He is an amateur astronomer and member of the Amateur Astronomy Association "Achyrostrata" (named for an ancient word for our galaxy used by local people), based in the Delphi Municipality. He speaks English, French, German and some Italian and currently works in computer programming, software and social networking. Astrology of the 13 Signs of the Zodiac: Ophiuchus: The New Sign of the Zodiac Circle is his first book.

The role of Sunspots in Astrology

A natural and astrological variable that affects the temperament of every individual, is the number of sunspots at the time of everyone's birth. It is an important parameter in the personality of the person and we all understand that there is big difference between a child born when the Earth is bombarded by solar wind, and a child born when the Sun is in a recession of its activities. The "Astrology of the 13 signs of the Zodiac" contains a theory linking the intensity of the solar wind (and the number of sunspots) with the temper and temperament of each individual.

The table that gives as the ratio and the connection between the number of  Sunspots and the characteristics they give to every man, is found in an autonomous chapter of the book ""Astrology of the 13 Signs of the Zodiac" by Vasilis Kanatas" and is an integral part of the New astrological theory.

The Moon is the new Ascendant

Today we know that the ascendance of a particular zodiac constellation at the time of birth of a child has an insignificant influence on it. The constellations which correspond to the Ascendant are comprised of stars which are at a distance from 10 to 3000 light years away.The same applies to the Midheaven (MC), the Nadir (IC) and the Descendant (Desc) of the zodiac constellation at a persons time of birth.

The word “horoscope”, derives etymologically from the Greek words “Ora” (ora = hour) and “skopos” (skopo = observe).In astrology it has the meaning of observing something at the time of the birth of a baby.In Western Astrology the “Horoscope” in the Greek sense is translated as “Ascendant” in English, that is, the Zodiac constellation which is rising in the East at a persons time of birth. The Horoscope as an observation of the phenomena at the moment of birth may be, as we will show below to ultimately be the case, something more than the Ascendant.

Our Horoscope in the modern age is, as we will see, independent of the geographic position of a persons birth. The position of the Moon on the ecliptic is independent of our latitude and longitude,and by extension is independent of the place of birth of each person.Therefore the appropriate indicator which could point to the personality of each person is the exact position of the Moon on the ecliptic (at their time of birth).This is our Horoscope, our Ascendant. Just as the Moon stabilizes the Earths orbit, so is our character regulated by it.

Thus the Moon represents our ego, our character. It defines our relationships in life, our constitution, finances and our relationships with siblings and family.

Given its clear relationship with the tides of the seas, rivers and lakes, we can theorize that the Moon governs all things related to the water element.

Book description:

Astrology of the Thirteen Signs of the Zodiac is a book which explains a new theory in this ancient field of study.It was prompted by the fact that Western Astrology has outlived its lifetime and its elements have been rendered obsolete by its cousin, the science of Astronomy.The precession of the equinoxes, that is, the movement of the point of intersection of the celestial equator by the ecliptic by 50.2” (seconds of a degree) each year, prompts corresponding discrepancies in the predictions of astrology, which move further and further away from reality with each passing year.Since 100 A.D., when Claudius Ptolemy wrote his Tetrabiblos, the zodiac constellations have moved approximately 29.2° across the sky, enough to ensure that the predictions of Western Astrology are completely misguided.


The Astrology of the 13 Signs of the Zodiac takes into account all available modern scientific information regarding the actual positions of the 13 Zodiac constellations and offers Astrology a way out.The only reasonable path now available to it is the acceptance of the 13 Signs of the Zodiac and the new theory, on the basis of which the Moon and the Sun are given their rightful place.In 13 Zodiac Sign Astrology, the Ascendant is represented by the position of the Moon, the celestial body which truly affects our lives, and not by some distant constellation.Lastly, sunspots, which have a well-documented impact on the Earth and its people, take on an important role in the New Astrology.


Only the Astrology of the 13 Signs of the Zodiac is firmly grounded in the sciences, and particularly in Astronomy.It recognizes the influence that the planets have over our lives through their interactions with the Sun and the disturbances they cause in its magnetic field, and the effect this has on the magnetic field of the Earth itself.

Book reviews:

Thursday, 8 February 2013, Buhle's Bookself (

Astrology of the 13 Signs of the Zodiac offers a new theory of Western Astrology designed to make it compatible with the science of Astronomy. (The new sign is Ophiuchus; it comes between Scorpio and Sagittarius). Chapters outline a perspective of the Moon - a celestial body that is much closer to us and has a greater effect on our daily lives than faraway constellations - as the Ascendant. Sunspots also play a greater role in this new astrological method, designed to correct imbalances such as those that come simply from the constellations slowly shifting position in the sky ever since ancient times. A wealth of black-and-white illustrations complement this methodical walkthrough of a new way for gleaning metaphysical wisdom from the night sky.

The "Astrology of the 13 signs of the Zodiac"was a pleasant reading and an eye-opener. It explains,in layman's terms, the fallacies of traditional Astrology and adds a new perspective in Astrological readings by taking into account the influence of sun spots.A brilliant idea and one which makes sense as it is based on Astronomy.

The book ,in my opinion,is easy to read, has the right length and with the use of diagrams and pictures gets the main message across without getting into many technical details that might confuse the average reader.All in all an innovative approach to Astrology and a pleasant reading for those that want to discover its scientific roots.

I was given this book as a gift. Very impressive! I wasn't an avid follower of astrology, just here and there, but I found your book enlightening. The science is explained in a way that even I understood what was going on. Surely it's obvious there's a 13th star sign. Are you coming out with any more books on this subject? I'll keep my eyes open.

Moon, the New Ascendant of modern Astrology

To make an astrological system to withstand time and mainly the control of related sciences such as Astronomy, we should be putting new items documented on today and the scientific studies of the recent years.

So the old Rising Sign, called Ascendant, that is the rising sign at birth, could neither have scientific support nor value. Even more it cannot affect a person's life literaly as a clump of rising stars at birth time. I am saying this because there are no similar studies supporting the influence of the rising sign in our lives. The only reason to be used by the Western and other Astrologers today is historic. They got the Ancient Greeks Horoscopic legacy and with no questions, they adapted the Ascendant of the riging Sign, they learned to work with it and do not like to see it changed.

For these reasons, therefore , and especially to adapt Astrology in facts that affect our lives, 13 Zodiac Astrology introduced a new Ascendant, which is the Zodiac Sign of the Moon on the ecliptic. Where ecliptic is the belt on which the Sun moves in its apparent annual orbit around the Earth. The Moon, several times removes from the Ecliptic zone and enters neighboring Constellations, thus for simplicity and substance reasons, we calculate her trace on the ecliptic as her real Zοdiac Sign (the nearest point of the ecliptic).

The Moon as the New Ascendant influences our lives not only at the time of birth, the first breath, but any other time in our lives. She passes every 29.5 days from the point where the Sun was when we were born. She also returns every 29.5 days at that point she was when we were born, and as we shall see, she has psychological effects onto any man on Earth.

But exactly how the Moon affects the animals and plants of our planet ? Through what processes is her presence sensed?

To make all these understood we need, first of all, to talk about clocks, or even better, for biological systems of recording time. Systems contained in all living organisms on our planet.


1. So there is a circadian time recording system based on the Sun. It counts days and nights. It has a period of 24 hours.
2. There is the lunar system that measures the return of Moon over the meridian of the a place on Earth, every 24.84 hours (24h 50m). It produces 2 times tide and 2 low tide.
3. The semilunar system counts tides every 12.42 hours (12h 25m)
4. The monthly lunar system that is a multiple of the lunar system. We just separate it from the lunar system because some animals use the Full Moon or New Moon in their biological clock.

Every organization on Earth involves, as we shall see in the examples, one or two biological clocks, under which, they are nourishing, sleeping, reproducing and performing every other biological process.

Let's see some examples of beings and their associated biological clock according to 9 studies :

1. Noble Crayfish Astacus astacus, uses monthly lunar biological clock for reproduction in the days of the New Moon . Study : 3Adoi% 2F10.1371% 2Fjournal.pone.0068653

2. Oysters of Connecticut (USA). Semilunar biological clock. According to experiments of Professor Dr. Frank A. Brown of Northwestern Unibversity Illinois, oysters collected in the U.S. East Coast , Connecticut , which opened every high tide (every 12.42 hours) were transferred to the laboratory in Chicago. In a darkened room. Originally oysters followed blinking to the rhythm of the place where they were caught. On the second week, the rate was coordinated with the time that the moon passed over the meridian of Chicago. It is obvious that oysters perceive through gravitational pulls the Moon's position and coordinate their biological clock.
The same professor in another study found that vegetables consume more water just before Full Moon . They own monthly lunar biological clock.

3. The stippled sea lice (Eurydice pulchra) According to a study by Charalambos Kyriacou, Geneticist Biologist, University of Leicester, has two parallel biological clocks. A circadian and a semilunar. Both biological clocks regulated by natural processes from which they derive, by the day - night the first and by tides the other.

4. The hairy worm Platynereis dumerilii, according to a recent survey by Kristin Tessmar-Raible at the University of Vienna and its partners, it has two biological clocks: The circadian ( day - night ) with which it feeds . And the Monthly Lunar every 29.5 days, to be reproduced !

5. Protozoa: Ray and Chakraverty (1934) reported that the ciliate Conchophthirius lamellidens, parasitic in a freshwater mussel, conjugates most freely after full moon. This example, although cited in subsequent literature, has not been studied further, and no causal mechanism is known.
Coelenterata: Moore (1958) noted that a species of Pocillipora breeds throughout the year, but with a lunar rhythm. In winter, breeding is related to full moon and in summer to new moon. There is no correlation with tides, since in the winter the lowest neap tides are related to full moon and in summer to new moon. Response of the animal appears to be to tidal amplitude, water pressure, or air exposure. The rhythm is an irregular lunar-monthly one.

6. A sea anemone, Actinia equina, has a tidal rhythm in its cycle of expansion and contraction; although this would seem to be a simple case of direct response to tidal stimuli, the rhythm persisted in the laboratory for several days (Cloudsley-Thompson, 1961 , after Pieron, 1958).

7. Platyhelminthes: Gamble and Keeble (1903) found that the intertidal flatworm Convoluta roscoffensis rises to the surface when the tide is low and retreats when the tide rises. The movements do not occur at night. This apparently simple tidal rhythm persists in the laboratory and so has some internal timing mechanism.

8. Evidence for the influence of selenium in the human sleep cycle . (Evidence that the Lunar Cycle Influences Human Sleep)

3 Centre for Sleep Medicine, Hirslanden Clinic, 8702 Zollikon, Switzerland

Here we show that subjective and objective measures of sleep vary according to lunar phase and thus may reflect circalunar rhythmicity in humans. We found that around full moon, electroencephalogram (EEG) delta activity during NREM sleep, an indicator of deep sleep, decreased by 30%, time to fall asleep increased by 5 min, and EEG-assessed total sleep duration was reduced by 20 min. These changes were associated with a decrease in subjective sleep quality and diminished endogenous melatonin levels.

Thus humans contain at least two biological clocks, a circadian ( day - night ) and a monthly Lunar.

9. Another study by Doctor Michal Zimecki, "The lunar cycle: effects on human and animal behavior and physiology", captures the effect of the moon and its phases on the female menstruation, melatonin levels in the blood, and the rate of births. Also in human behavior, such as accidents, crimes, suicides, Cardiovascular and other hospital incidents .
The study found correlation between the phases of the moon and these human cases requiring further investigation.

So we see that scientists have already found ways that the Moon influences behavior of animals, plants and the people on our planet. Certainly many unexplored fields remain in front of us. The investigation continues and we will watch with great interest the outcome.

Despite the efforts made so far, yet we can not have a complete theory of correlation and influence of the Moon on a psychological level. Intuition and our subconscious experience, beyond any doubt, are influenced by the Moon in everyday level and the proof is, our sudden mood changes depending on the day and the phase of the Moon.

The choice of the satellite of our Earth as the Ascendant of 13 Zodiac Astrology is therefore not accidental nor unsubstantiated. It is grounded in both scientific and empirical data. It is ultimately grounded in the deep, and thus true, voice of our subconscious ..

When a baby is born, the Earth, the Sun, the planets and the Moon are mainly in some parts of the sky and into phases that are possible, as we will see in another article, to multiple affect its life. Apart from illustrating the specific positions in individual global memory of the baby, the Sun, the Moon and other celestial bodies give every day of its life a reminder of their presence. This is natural but produces spiritual variations and has different effects on life.

And so, the point of the Eastern horizon of the place you were born, called rising sign (old Ascendant) is one of our birth data, but no one can seriously claim that this data can affect your life.

Just the opposite is true for the Moon ! The Moon is not a point in the sky ! It is a large and powerful celestial body that gives and takes affecting the body and soul. As such remains throughout the course of our life. This is our True Ascendant ! Over and above any doubt ..
