A Lenticular Seyfert Galaxy

NGC 5283 is a lenticular galaxy, and like about 10 percent of all galaxies, it’s also a Seyfert galaxy with and active galactic nucleus (AGN). An AGN is an extremely bright region at the heart of a galaxy around its supermassive black hole. When dust and gas fall into the black hole, the matter heats up and emits light across the electromagnetic spectrum. Some AGNs emit so much radiation they outshine their host galaxies. Seyfert galaxies differ from other galaxies with AGNs because the galaxy itself is clearly visible.
