Seyfert galaxy

A relatively normal-looking spiral or disk galaxy with a clearly visible host disk and spiral arms, sometimes with faint diffuse outer structure or an oval body, but dominated by an exceptionally bright compact active nucleus at the center. The nucleus appears nearly stellar and intensely luminous, as a white-blue to yellow-white core that outshines the inner bulge and stands out strongly against the surrounding galaxy. The host galaxy shows soft bluish spiral arms, a yellowish central bulge, and subtle dust lanes, with the bright core surrounded by a slight glow emphasizing the active galactic center.
