小众目标，曾经在里面发现过超新星。NASA是如下介绍的(懒得翻译了）：
NGC 3184 is a largespiral galaxy with a small nucleus and long sprawling spiral arms. AlthoughNGC 3184contains hundreds of billions of stars, the blue color of itsspiral armscomes mostly from relatively few bright young blue stars. The galaxy is not empty of matter between thesespiralarms -- the bright stars that highlight the arms were created in hugedensity wavesthat circle the center.Visiblewith a small telescope towards theconstellationofUrsa Major, light takes about 25 million years to reach us fromNGC 3184---------NASA
