According to my astrologer, the signs stay the same as they always have. If you read past the "hysteria" of the signs changing, you will learn that scientist have known about this alleged new sign since the beginning of Greek astrology. Obviously, it wasn't important to them, so it shouldn't be to us Stick with the originals.
The "new" sign (Ophiuchus) has actually been around for a while, just someone decided to make a big deal out of it now for some reason. It's a matter of if you follow "sidereal" versus "tropical" astrology.
