Just like on Earth, dust is everywhere in space. Dust particles absorb and scatter light, confounding astronomers that try to see through them to study stars within the Milky Way as well as the galaxies that lie beyond it. Although it is difficult to measure the impact of dust on a single star, combining the colors of ~1 billion stars has allowed us to start creating detailed 3-D maps of the dust within our galaxy. I will discuss the various challenges associated with these efforts, how astronomers have tried to approach solving them, and how data from the Gaia satellite in the past year have led to new, exciting breakthroughs in characterizing the 3-D structure of dust in the local Solar neighborhood. I will also discuss promising developments for these efforts going forward.
