Milky Way Structure Part 1

This video is about the structure of our home galaxy, the Milky Way. It covers how we can figure out what our Galaxy looks like while being embedded within it and how we determine our location within it. It also covers how we use Cepheid variable stars to measure great distances and how we measure the mass of the Galaxy, including all of the dark matter, using the rotation curve.
