The Triangulum Galaxy, M33
Located in Triangulum, M33 is large and bright (visual magnitude +5.8) and a fine example of a loosely wound spiral galaxy. It is a member of our Local Group of galaxies and about 3Mly away. The unusually blue appearance is attributed to the substantial number of bright blue stars present and, even at this distance, blue and red supergiants are resolved together with numerous star clusters, red emission regions and dark dust lanes.
