We qualitatively study the effects of gravitational microlensing on our viewof unresolved extragalactic star formation regions. Using a generalgravitational microlensing configuration, we perform a number of simulationsthat reveal that specific imprints of the star forming region are imprinted,both photometrically and spectroscopically, upon observations. Suchobservations have the potential to reveal the nature and size of these starforming regions, through the degree of variability observed in a monitoringcampaign, and hence resolve the star formation regions in distant galaxieswhich are too small to be probed via more standard techniques.Comment: 7 pages, 8 figures, ApJ accepte
