NGC 5253 (1337-3123) -- This nearby (4.1 Mpc; Sandage et al. 1994) starburst galaxy has been studied from radio to X-ray wavelengths, including IUE UV spectroscopy, which has revealed Wolf-Rayet spectral features (see Kinney et al. 1993, and references therein, for a summary). The FOC image presented here has been extensively studied by Meurer et al. (1995). This archival HST image is a 500 s exposure with the F220W filter plus a F1ND neutral-density filter, which provides a factor 2.5 attenuation in flux. The exposure is therefore 1/3 as deep as our standard-setup exposures. Nevertheless, the image shows numerous bright sources. As shown by Meurer et al. (1995), these are compact young star clusters of the type detected with HST in other starburst environments, as well as individual stars. This galaxy has the highest total UV flux in the sample. |
