Do you know a difference between a dwarf spheroidal and a dwarf elliptical? This poster shows all the major morphological and other types of galaxies based on different criteria. Mass, radius, luminosity, and surface brightness, µ, is provided to orient yourself quickly in the puzzling world of galaxies.
For educational use only. 300 dpi version of this poster is available upon request. I have tried to retain copyrights and give credit to the original image authors wherever possible, however, due to time constraints could not have done so for all the objects.
