WebSeyfert galaxies comprise ~ 10% of all galaxies. Seyfert 2 galaxy NGC 7742 Credit: AURA/STScI/NASA As well as Seyferts, other galaxies are also classified as AGN. These include radio galaxies, quasars, blazars and LINER s. Radio galaxies, as their name implies, are strong emitters of radio emission. WebEdwin Hubble classified spiral galaxies of this type as "SB" (spiral, barred) in his Hubble sequence and arranged them into sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms, while SBc types are at the other extreme and have loosely bound arms. SBb-type galaxies lie in between the two.
