“There, peeping among the cloud-wrack above a dark tor high up in the mountains, Sam saw a white star twinkle for a while. The beauty of it smote his heart, as he looked up out of the forsaken land, and hope returned to him. For like a shaft, clear and cold, the thought pierced him that in the end the Shadow was only a small and passing thing: there was light and high beauty for ever beyond its reach.”

Ophiuchus!? What now?
via Sagan's Brain

6th century zodiac wheel, Beit Alpha, Israel

It was widely reported that not only is Ophiuchus a new sign that we'll all have to learn to live with, but that the precession of the Earth's axial rotation has, over a few millennia, shifted our view of the sky so that the Sun is no longer in the same apparent position along the zodiac as it was thousands of years ago, when this version of astrology was concocted.  In other words, people with birthdays in late March have traditionally been considered Aries, but today the Sun is really in Pisces at that time of year.

This story is just so silly in a variety of ways.  For one thing, it wasn't actually news.  The Earth's precession doesn't happen overnight, and astronomers haven't just discovered it (read this discussion of the problem by Phil Plait way back in 2008)..  In the words of Sam Cooke, it's been a long time coming.  Then there was the panic and irritation that the traditional signs are all wrong (HuffingtonPost cleverly examined the Earth-shattering consequences of this shift).


Soon after this news, astrologers came to the rescue.  Nothing to fear, they said.  The Ophiuchus shift only applies to Sidereal Astrology, not Tropical Astrology.  Most believers probably don't know the difference, but don't worry, we westerners typically believe in Tropical Astrology, which is unaffected.  "Ophiuchus only affects those who were born 2009 onwards. If you're born before 2009, the sign stays the same."  That's a relief.


The signs originated from the constellations, but are not the same thing. The signs are composed of 12 equal subdivisions of the sky, each 30 degrees in extent. The constellations are not laid out in such an orderly fashion.


There are thirteen astronomical constellations that cross the ecliptic. Whenever you refer to the zodiac use the number thirteen and name the constellations of the ecliptic (see Table #l). If someone complains that these are not the right constellations, just point out that all constellations are arbitrary and strictly artificial. The ones we use are the official constellations of the International Astronomical Union.

So, if Ophiuchus occupies more of the ecliptic than Scorpius, why is it not in the astrological zodiac instead of Scorpius? Ancient astronomers did not place Ophiuchus on the ecliptic; it is the modern construction of official constellation boundaries that gives it so much territory across the ecliptic. Since they are rather arbitrary boundaries, it doesn't make much difference. Most likely, it's because Ophiuchus is not a particularly bright constellation, while Scorpius is a very bright, vivid group of stars that really does look like a scorpion.


It remains to be seen whether the new dates for the 12-sign zodiac will be adopted, whether we'll keep the dates as we have come to know them, or whether we'll switch over to the new 13-sign zodiac.

I also have the spontaneous urge to discuss my Zodiac sign:

Aries

Aries is the first sign of the zodiac, the leaders of the pack, first in line to get things going. Whether or not everything gets done is another question altogether, for an Aries prefers to initiate rather than to complete. The leadership displayed by Aries is most impressive, so don't be surprised if they can rally the troops against seemingly insurmountable odds -- they have that kind of personal magnetism. An Aries won't shy away from new ground, either. Those born under this sign are often called the pioneers of the zodiac, and it's their fearless trek into the unknown that often wins the day. Aries is a bundle of energy and dynamism, leading people along with its charm and charisma. The dawning of a new day -- and all of its possibilities -- is pure bliss to an Aries.

The symbol of Aries is the Ram, and that's both good and bad news. Impulsive Aries might be tempted to ram their ideas down everyone's throats without even bothering to ask if they want to know.Along with those qualities comes the sheer force of the Aries nature, a force that can actually accomplish a great deal. Much of Aries' drive to compete and to win comes from its Cardinal Quality. Cardinal Signs love to get things going, and Aries exemplifies this even better than Cancer, Libra or Capricorn.

Aries is ruled by Mars, the God of War. Unafraid to do battle, these folks are bold, aggressive and courageous. They can summon up the inner strength required to take on most anyone, and they'll probably win. Aries do not lack energy or vitality, and they can stay in the game longer than most anyone else. Now that's a winning edge. Rams are also, for the most part, independent and well aware of their own interests in a given situation.

The element associated with Aries is Fire. Think action, enthusiasm and a burning desire to play the game. Aries love physicality, so they won't sit on the sidelines for long, if at all. They'll jump into the fray full force and will contribute much in the process. Aries also play as hard as they work ;)

In personal relationships, Aries natives are frank, high-spirited, direct and candid. They make for enthusiastic and generous friends, but need to curb their competitive impulses and the manner in which those impulses affect those around them. Subjects of this Sign also need to learn how to temper their natural aggressiveness and use reason--coupled with diplomacy--when dealing with others. Since those governed by Aries like to get their own way and often pit the wishes of self against what is best for any partnership, this can frequently lead to conflict. The capacity for deep affection should result in faithfulness with regard to both love and friendship, but these natives need to guard against an inclination toward jealousy and/or over-possessiveness. 

The great strength of the Aries-born is in their initiative, courage and determination. These folks love to get things going and are fearless along the way. Their dynamism and competitive spirit add considerably to any of their endeavors.
