We present an analysis of ultraviolet, H-alpha, and infrared images of the Large Magellanic Cloud to study the LMC's star formation and dust emission. The infrared images are the new Spitzer SAGE Legacy IRAC and MIPS images with wavelengths from 3.6 to 160 micron. The ultraviolet image at 0.15 micron is from a rocket flight (Smith et al. 1987) and the H-alpha image is from SHASSA (Gaustad et al. 2001). The ultraviolet, H-alpha, and MIPS 160 micron images have a similiar resolutions of around 40" allowing for the study of this galaxy at approx. 10 pc resolution. These images allow us to probe the detailed behavior of the dust emission (heating sources and aromatic features) and star formation tracers for both young stars (H-alpha+24 micron, < 10 Myrs) and somewhat older stars (UV+IR, < 100 Myrs). The results of this work have implications for understanding star formation and dust emission in the LMC as well as understanding the same in more distant galaxies.
