Notes

M33, The Pinwheel Galaxy, is a prominent member of our Local Group of Galaxies. It is the second closest galaxy to the Milky Way at a distance of 3 million light years. Spanning between 50,000 and 60,000 light years across its major axis, M33 is about half the size of our Milky Way galaxy and is very much dwarfed compared to the Local group's giant member, The Andromeda Galaxy. M33 teems with structural detail and has at least 16 features within it's boundaries that are assigned either an IC or NGC designation. Numerous HII areas, bluish clouds of young stars, and fine dust lanes adorn the spiral arms of this fine object.
