Video on the Milky Way Galaxy

I was talking in class about an episode of "The Universe" specifically on the Milky Way Galaxy. This is the episode I was talking about. They get into detail about black holes at the center of galaxies, what it is like near the center and the edge of a galaxy by the Milky Way, etc..... Watch it on You Tube. I have attached a link for what I showed in class. You can watch the other portions of this episode on YouTube also.

There are other episodes of "The Universe" that can be found on Hulu such as documentaries on Quasars and Pulsars, Nebulas, etc.... Check them out.
