Claim: Some astrologers, who study celestial objects and phenomena, believe that a ring galaxy is formed when a smaller galaxy goes through the middle of a larger galaxy.
Evidence: Some astronomers believe that ring galaxies are formed when a smaller galaxy passes through the center of a larger galaxy. Not to be confused with astrology, a pseudoscience. Astronomy (from Greek: ἀστρονομία, literally meaning the science that studies the laws of the stars) is a natural science that studies celestial objects and phenomena. Astrology is a pseudoscience that claims to divine information about human affairs and terrestrial events by studying the movements and relative positions of celestial objects.
