No, the 13th sign of the zodiac doesn’t discredit Astrology
Ok so if you don’t believe in astrology, that’s totally cool, hopefully there’s no one in your life shoving astrology down your throat, and reading you your horoscope every morning. Most people can take it or leave it with little consequence. But it’s hard to understand why the haters are always trying to ruin it for the people who enjoy it.
Periodically this 13th sign thing comes up... Yeah there is a 13th constellation called Ophiuchus. It’s visible, so to say that the ancient astrologers/astronomers didn’t know it was there, would be silly. “Ophiuchus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations.” It isn’t new, NASA never said it was new either. The sensational articles about it are just clickbait.
The ancient astrologers divided the ecliptic into 12 sections of 30 degrees and named it the zodiac. It’s loosely based on 12 constellations and the qualities attributed to them. It was always an abstraction and not a concrete representation of actual constellations. It’s like a sketch, and not a photograph. By design, the zodiac was not meant to be reflective of of what is seen in space from earth, so it doesn’t make sense to discredit it based on what it never meant to include in the first place.
And finally, if you plan on studying astrology or using it in any way, get ready for much more ambiguity. There are many different house systems, most will give you a different layout of which planets fall within these houses. This may drastically change how your chart is read and what it means. Is there a right or wrong? Not exactly. It’s sort of like looking at the same thing from different angles, and some of these angles are very different indeed. Most astrologers pick a house system that resonates with them, or they may cross reference with one or more others to fill out the reading and give more depth. Some are die hard one system and then switch to another one at some point in their practice. Astrology is quite fluid, and that may be why it attracts so many critics. We like things concrete and scientifically proven, while things elusive make many uncomfortable.
