Did you know there are several different astrological house systems? Astrologers love to debate the value of one system over another, but perhaps a more enlightening inquiry centers around why ...and how each system developed, and what might be the best practical application for each.

Is Ophiuchus the 13th Zodiac Sign?
Skeptics cite the existence of a 13th constellation located along the ...
Skeptics cite the existence of a 13th constellation located along the ecliptic in regular attempts to invalidate astrology. The Sun, in its apparent motion through the sky, travels through the ...constellation Ophiuchus (The Serpent Bearer) from approximately November 30 to December 18, every year.
What, if anything, does this say about the practice of astrology?
Should astrologers concede defeat, and everyone adopt a new Sun sign?
Join Kepler College faculty members Samuel Reynolds and Mary Gaterud for a discussion on the merits of this argument: how constellations are not zodiac signs, the possible motivations for this recurrent debate, effective ways astrologers can respond, and what the symbolism of Ophiuchus might suggest for students of astrology.

And, for further study, a response from another esteemed astrologer and Kepler College faculty member Anthony Louis to a recently published, sensationalized salvo:
