Thermal Radio Emission from HII Region S201
Structure of the ionized gas near the surface of a molecular cloud. Note the sharpness of the ionization front in the northeast part of the picture, at the interface with the molecular cloud and the smooth decrease in the opposite direction where the ionized gas is free to expand.
