We have recently developed the most efficient technique known for finding distant galaxies. In our sample of 33 4C sources, at least 8 are galaxies with z < 2, and 2 have z > 3.7 The galaxies emit bright narrow Lyman alpha which is extended, usually by several arcseconds. Their optical contin ua are also extended. These high-redshift objects show the striking align ment between their optical and radio emission that we (unexpectedly) found to be a general property of distant radio galaxies. Here we propose to study two z > 2 galaxies with the HST. Our program is directed towards imaging the galaxies in Lyman alpha and in t he continuum with the WF to obtain morphological information about the var ious components. Our distant radio galaxies are the only high-redshift objects that can be mapped in detail with the HST. This project will provide unique information about the properties of galaxies in the early universe, close to the epoch of their formation.
