We present results from an investigation of the peculiar "Tadpole Galaxy" (UGC 10214) using mid-infrared imaging from the Spitzer Wide-area Infrared Extragalactic Survey (SWIRE) observations of the ELAIS N1 region, which includes UGC10214 and its local environment. The Spitzer imaging data comprise the four mid-infrared channels of IRAC and the 24-micron MIPS observations. To supplement these mid-infrared data, we have (1) carried out a ground-based program to image the Tadpole at high resolution in the optical and near-infrared windows, and (2) systematically searched through publicly available astronomical mission archives. We show that the prominent "blue" super-cluster star formation regions discovered with HST-ACS are clearly detected in the mid-infrared, indicating the presence of both thermal hot dust and hydro-aromatic carbon molecules in these regions.
