I belive its' valid science, in early periods of history, scientists and philosophers studied astrology and the other sciences(astronomy) hand in hand, but because of religious movements and revolutions in Christianity, astrology was separated as a false less serious science. I think its a fascinating tool to use to understand ourselves, but I combine numerology, and some other studies to try to get a better more insightful understanding. Astrology by itself can be very detailed and complex depending on what you want to use it to find out....you have your rising sign(based on time of birth), then moon, mars, venus, jupiter, saturn, etc, signs; then you can find out which of 12 houses they are located at in your chart. this info tells you about your ideal career, love life, childhood, partnerships, etc. You can pay an astrologer to do this 4 you.
