The Hubble Space Telescope has imaged lenticular galaxy NGC 5283, a Seyfert galaxy with a visible structure and an active galactic nucleus. The observation is part of a dataset survey to study AGN physics, black holes, and galaxy structures. The lenticular galaxy NGC 5283 is the subject of this N
NGC 5283 is a Seyfert galaxy. About 10 percent of all galaxies are Seyfert galaxies, and they differ from other galaxies that contain AGNs because the galaxy itself is clearly visible. Other AGNs emit so much radiation that they outshine or make it impossible to observe the structure of their host galaxy!
