Spiral galaxy NGC 3185 is about 80 million light-years away from us in the constellation of Leo (the Lion). The galaxy’s spiral arms swirl outward from the center of the galaxy toward the rim where they join a blue disk of young stars. At the galactic center of is a small but very bright nucleus containing a supermassive black hole. Supermassive black holes have masses many thousands of times that of our Sun, and they become active as matter falls towards them. When this happens the black hole lights up, sending away streams of particles and radiation at almost the speed of light.
NGC 3185 is a member of a four-galaxy group known as Hickson 44. NGC 3190 is a somewhat more famous member of the group. Apple used a blue-tinted image of it as the default wallpaper for its Mountain Lion operating system.
