types of active galaxy
The different features of an active galactic nucleus (AGN), and how our viewing angle determines what type of AGN we observe. The extreme luminosity of an AGN is powered by a supermassive black hole at the center. Some AGN have jets, while others do not. Image credit: Aurore Simonnet, Sonoma State University
An active galaxy is any galaxy with an active galactic nucleus.
