We investigate star formation in the Sc(s) II-III galaxy M33 by analyzing eight prominent HII regions using multi-wavelength data from the Spitzer Space Telescope and optical imagery. Results indicate that dust emission is a compact tracer of high-mass star formation, while PAH and H-alpha emissions decline more slowly with galactocentric radius.
