Based on Government Sponsored Research NAS7-03001 and NNN12AA01C. The Milky Way Galaxy is organized into spiral arms of giant stars that illuminate interstellar gas and dust. It is about 100,000 light-years across and about 10,000 light-years thick. The Milky Way might be right on our cosmic doorstep, but a group of astronomers suspect that the way we currently study it is stunting our understanding. It is so big that light takes 100 000 years to cross from one side to the other. I see a description of the galactic disk (and mention of the dark matter halo) but no mention of the other major components of the Milky Way, namely the galactic halo and bulge: http://en.wikipedia.org/wiki/Bulge_%28astronomy%29.
