Ok. Let's get this straight.

This is a sore point for people with my particular hobby, so please carefully note the following.

Astronomy is the science that studies the stars, the planets, comets, asteroids, and all the other stuff out there in space.

Astrology is a pseudo-science upon which the superstition called the horoscope is based.

Parke Kunkle is a Minnesota scientist, not an astrological charlatan. He recently caused a furor by pointing out what real scientists- astronomers- have known for centuries: first,  that the horoscope's supposed correspondence of the signs of the zodiac (the constellations through which the Sun's "path-" the ecliptic, which from another perspective is simply the plane of the solar system) seems to travel when seen from Earth) with the calendar is in fact an entire month off, and has been for centuries; and, secondly, that the sun's path actually travels through thirteen constellations, and not only twelve (Ophiuchus, the Serpent Bearer, is also a zodiacal constellation, though omitted for some reason from the astrological "zodiac").

In other words, that the entire basis of astrology and the horoscope is sheer bunk.

Here's the straight dope. There's nothing new in all this, mind you; just something that those who are interested in the scientific study of the heavens, rather than superstitious hokum, have taken as a given for a very long time.
