Spitzer Space Telescope/MIPS observations of M31 provide an unprecedented opportunity to study the structure and composition of the inner few kpc of the Andromeda Galaxy (one 24um field of view is about 1 kpc at the distance of M31). There is abundant data in the literature on the structure and kinematics of the gas for M31, and for other nearby spirals. But, prior to Spitzer it has not been possible to study the morphology of the dust and stellar components at such high sensitivity and spatial resolution. We present the MIPS imaging of the central region of M31. The data are extremely rich and provide information relating to many types of studies, ranging from stellar populations and distribution to the composition and structure of the interstellar medium. Early results are presented from our studies of the stellar and dust components - distribution, composition, and temperature structure.
