With Spitzer, we can peer right into the heart of our own galaxy and see breathtaking detail. This picture is crammed with fascinating features that we have just begun to explore.

Our Spitzer data, combined with data obtained by other telescopes, will allow us to determine which of these objects are truly at the galactic center, and which are in spiral arms along the way. This survey will help us to better understand the mass distribution and structure of our own galaxy and how it compares to other galaxies.
