How Astronomy Begat Astrology
I'm a naked eye astronomer, as were all astronomers before the invention of the telescope, four centuries ago. I love to watch the sky at night, observing the slow dance of the planets amongst the stars.
Today we get only a dim glimpse of what earlier peoples must have seen in skies free from dust pollution and, in urban areas, from the light pollution that bleaches out all but the moon and brightest stars.
Here are some things you can see in the evening sky, after sunset, as the never-repeating, never-ending, cosmic dance continues.
Mercury is usually hard to see because its stays close to the sun. It orbits the sun once every 88 days, and so alternates between evening sky and morning sky approximately every 6 weeks. It greets the four other visible planets together in the morning sky of late Jan. A line of Mercury, Venus, Saturn, Mars, Jupiter.
Venus is high in the morning sky early 2016. Indeed at the beginning of the year there are no planets in the evening sky. They are all together in the East in the pre-dawn sky.
Mars early 2016 is in the morning sky, rising earlier and earlier throughout the Spring, reappearing in evening sky and at its brightest high above in May.
Jupiter is also in the morning sky - see above - but highest of them all, and reappears in evening sky in early Spring.
Saturn is low in the morning sky.

The twelve Zodiacal constellations (Taurus, Pisces, Gemini, etc.) also lie on the ecliptic -- they are the constellations the planets pass through.
