Did you know that you need to be very careful in when evaluating information that people claim is scientific. Some things look like science but the knowledge gained came from means other than proper scientific investigations and debate.
Astrologers have been studying the stars since ancient times. They use observations and statistical methods to make predictions. They also consider beliefs about gods and powers when making their predictions. Although astrology is founded on observations and uses some aspects of science it is not a true science because it takes into accounts aspects of belief and religion. We call this type of science a pseudoscience.
Astronomers study the stars and make observations about the Universe and beyond. They perform scientific investigations that use the scientific method. They make predictions from proven laws of Physics and Statistics. Astronomers cannot take into account beliefs only scientific Laws and known facts.
