This site discusses the different types of active galacties: Double-Lobed radio galaxies, Seyfert Galaxies, BL Lac Objects, and quasars. These pages discuss the structure, components, behavior, and provide an image or diagram for each type. It also provides information about the role black holes may have in understanding active galaxies and an image of a suspected black hole at core of a NGC4261. This site ends with a short quiz.
