Determining the contribution of galaxies to the reionization of the universe is a fundamental goal for studies of the intergalactic medium (IGM), and galaxy formation and evolution. A direct measurement of ionizing Lyman-continuum radiation escaping from galaxies is not possible at the epoch of reionization, due to the high optical depth of the IGM, and therefore observations of this process at slightly lower redshift are crucial for understanding what happens at z~6. Building on previous spectroscopic detections of escaping Lyman-continuum radiation, I present new results based on narrowband imaging. The high level at which especially the faintest objects are detected challenges standard models for the escape of ionizing radiation from galaxies. Furthermore, the detailed relationship between the spatial distribution of ionizing and non-ionizing radiation will provide important insights into the process through which ionizing radiation escapes. These new measurements provide a crucial ingredient for models of reionization.
