Just when you thought you could trust your horoscope, you find out your sign was wrong all along. Astronomers at the Minnesota Planetarium Society found that the moon's gravitational pull on Earth can result in a slight misalignment of the stars, leaving room in the calendar for a whole new sign: Ophiucus, the serpent wrestler a symbol of medicine and healing.
The shift from 12 Zodiac signs to 13 caused an online uproar among those who thought they had all their personal characteristics and fortunes figured out. But it turns out that ancient civilizations always intended the Zodiac to be divided 13 ways. It was in Babylon that the astrological calendar was reduced from 13 to 12, and Ophiucus was jettisoned from the realm of Pisces and Capricorn.
