One frequently asked question is a variation on 
the following theme. "My husband/brother/teacher says astrology is rubbish because the 
earth has moved since the time of the ancient Greeks. So when you astrologers say 
Jupiter is in Aries, it's actually in the constellation of Pisces... as you can see if 
you look at the sky." I always reply that the signs are deliberately different to the 
constellations. Today, in the light of all this nonsense about a new zodiac sign, I'd 
like to say a lot more.
There has, indeed, been a 'heavenly shift' since the time of the ancient Greeks. It is 
due to a phenomenon called the precession of the equinoxes. This is also the reason why 
every few thousand years, we get a new pole star. We astrologers have known all about 
this for ages. That's precisely why we decided, long ago, not to use constellations for 
our predictive work. They're unreliable and unequal. There are arguments over where 
they each begin and end. Plus, over time, they change. We needed some different way to 
measure the sky so we created twelve, exactly equal, mathematical divisions of the 
ecliptic. As the ecliptic is the path that the sun seems to follow through the sky, 
with the constellations behind it, we named each of our signs after one of those 
constellations. 
Are you with me so far? I do hope so. I really need you to follow me... because I'm 
desperate to explain something important. So desperate that I don't entirely trust my 
own ability to speak calmly. 
Every so often, I spend my weekend fielding phone calls from journalists who have been fed a 
cock and bull story about a 13th Zodiac Sign. It was given to them by a bunch of 
astronomers with a mission to make mischief. Rather than doubt a word of it, my fellow 
professionals (or at least some of them) immediately deferred to the 'scientific 
authority' of those stargazers. They then passed on the news through a million 
newspaper articles, blogs, tweets and even Youtube videos.  
 
The result, for me, has been an endless stream of ridiculous questions. "So Mr Cainer, 
what will you tell your readers now that scientists have proved that there's a new 
zodiac sign and that the other signs now have different dates?"
When I tell them that I won't be saying anything different because nothing has changed, 
they sound a bit disappointed. Some even suspect I may be hiding my head in the sand. 
But I'm honestly not in a state of denial. I'm in a state of despairing disbelief!
The worst of it is, I've been here before. Twice. Back in the mid nineties, a different 
astronomer tried exactly the same trick to get themselves some fame and discredit 
astrology. And quite early in my professional career, when I was so young, I still had 
hair, I had to help put out yet another Ophiuchus fire. I cannot tell you how ancient 
it makes me feel to be dealing with the re-emergence of this old chestnut. 
Anyway, let's return to the explanation. Several paragraphs ago, I explained that my 
predecessors named their twelve zodiac signs after the twelve constellations. This was 
entirely deliberate. They always knew, full well, that the signs and constellations 
would drift ever further apart over time. But they were happy enough to have set up a 
self-calibrating, permanently accurate set of zodiac signs, aligned to the equinoxes. 
And, for all their powers of prophecy, they never foresaw that one day, this would 
produce a whole new set of problems for a whole new generation of astrologers.
To the ancient Greeks, and the Babylonians before them, there was no separation between 
astronomy and astrology. The two subjects were one. In studying the sky, you would 
automatically read symbolic meaning into it. You needed to study the sky to a high 
standard because you needed to make the best possible predictions. Actually, this 
didn't change until surprisingly recently; the latter half of the 18th century, in 
fact. The great names in modern astronomy, like Galileo, Kepler, Copernicus and even 
Newton were just as interested in mystic interpretations as in measuring planetary 
orbits. 
These great astronomers knew perfectly well about the 'two different zodiacs'. They 
fully understood that you did your astrology with the mathematically equal divisions 
and that the constellations were for decorative purposes only. They also knew, 
perfectly well, that those constellations didn't match up with the equal zodiac signs. 
The 'drift' had begun to happen long before.
This begs a very big question. If Newton 'got it' and Galileo knew all about it, why 
was it such news to the Minnesota astronomers who planted the story in the papers late 
last week? What compelled them to declare a thirteenth sign called Ophiuchus and then 
issue fresh dates for the twelve zodiac signs as a result of their "research?" 
Could they really be so ignorant? Or were they, perhaps, determined to stir up as much 
publicity for themselves as possible no matter how many unfair aspersions this might 
cast on traditional astrology?
The sad, sorry answer is that their agenda was entirely aggressive. The schism between 
astrology and astronomy has grown in the last couple of hundred years, from a skirmish 
to an all out battle. Although so far, all the attacks have come from one side.
The astronomers have declared war on the astrologers. The astrologers, they feel, 
deserve it, purely by their very existence. How dare they believe what they believe? 
What right have astrologers to infer meaning into the movements of the planets when 
astronomers see no such mystic information and must content themselves only with 
measurements of orbit, rotation and chemical formation? 
Ironically, the astronomers' justification for their anger with astrologers sounds much 
like an accusation of heresy. The astronomers believe one thing. The astrologers 
believe another. And while the astrologers are happy to respect the astronomers' right 
to believe what they want to believe, the astronomers will seemingly not be happy till 
every last astrologer has been unceremoniously debunked. 
Fuelling this attitude is, of course, one very earthly factor. There's not much money 
in astronomy. You're likely, if you're studying space for a living, to be on a meagre 
academic grant. But some astrologers (only some, we must stress) make a good living 
from their practice. It must be galling for the astronomers to feel that their 
astrological cousins know far less yet are rewarded far more highly. 
Galling it may be. But then, they are perfectly free to return home to the realm of 
mysticism, aren't they? Well, oddly enough, they're not. We astrologers would welcome 
them into our communities with open arms. But peer pressure amongst astronomers is a 
formidable force. Across the scientific community there's a loathing and detestation of 
astrology, along with all other forms of semi-mystical activity, from telepathy to 
homeopathy. 
This shocking culture of bigotry means that if any researcher, no matter how 
respectable, at any university, no matter how progressive were to conduct a study of 
any esoteric activity... and was to conclude that there might be 'something in it after 
all', no matter how small, they would not be met with the applause of their 
contemporaries. Instead, they could expect to be rubbished in public, subjected to 
ridicule and put at the very bottom of the pile when it came to dividing up next year's 
grant money.   
So the astronomers don't like astrologers. And in fairness, astrologers are not always 
their own best friends, either. Each time, for example, you visit a horoscope website 
and see a picture of a zodiac sign made out of a kind of 'join the dots' image of 
heavenly stars, you're entering the territory of someone who is being, at best, a bit 
unthinking. Either they genuinely don't know that the constellations are not the same 
as the zodiac signs they work with... or they do but they're letting their art 
department get the better of them. Just to complicate the matter a bit more, there are 
some Indian astrologers, practising what they call Vedic astrology... and some genuine, 
knowledgeable people who have chosen to work as 'Sidereal astrologers', using visual 
astronomy... and these astrologers actually DO use the constellations. Which means they 
do use different dates. And, of course, they read the sky a little differently in much 
the same way, perhaps, as a musician might play a sitar differently to a guitar. Even 
they though, don't use an extra zodiac sign called Ophiuchus, or anything else.
The astronomers from Minnesota, who planted this mish mash of malicious misinformation 
into the press late last week, must now be rubbing their hands together with glee. But 
they've done their cause no real favours and they've done astrology no great harm. 
The fact remains that the zodiac is right, exactly the way it is. There is no new sign, 
there are no new dates... and sadly I predict that in 15 years or so, just when 
everyone has forgotten all this, some other smart alec astronomer will set out to cause 
the same trouble, all over again.
