Dreyer's description from his New General Catalog (NGC):
"Very bright, pretty large, extended 167°, abruptly much brighter middle very bright nucleus, star northwest."
Spiral Galaxy NGC 5033 is a member of the Virgo galaxy cluster. It has a small, very bright, but diffuse nucleus in a bright bulge that is an X-ray source and shows a spectrum of a Seyfert Type I active nucleus. (Also see our M-77 page for more on Seyfert galaxies.) The inner bulge has a spiral pattern of dark lanes. There are several thin spiral arms with branches. The arms are lined by many small H-II regions of star formation.
