We review the history and the current status of the understanding of the processes that regulate Lyman alpha emission from star-forming galaxies. We present some of the most recent results of our study to image local starburst galaxies in the Lyman alpha emission line using the Advanced Camera for Surveys on the Hubble Space Telescope. Particular attention is dedicated to our study of the low-metallicity, dust-poor Blue Compact Galaxy ESO338-IG04. We discuss some of our local observational results with reference to the interpretation of results of high-redshift Lyman alpha surveys and recent simulations of the detection properties of high-z Lyman alpha emitting objects performed by our group.
