Ultraviolet image of the SMC covering a similar field to that shown in Fig. 4. The shell features seen by the contribution of young stars are obvious in this near-ultraviolet image of the SMC taken by the Galaxy Evolution Explorer (GALEX, λ_eff ∼ 2271 Å, 17871 − 2831 #x00C5;, FWHM ∼5.5″). The field has been smoothed with a Gaussian kernel of FWHM 12 pixels (18″), and scaled to highlight the low-surface-brightness shell features. The region shown consists of 65 fields with a median exposure time of 866 s and a signal-to-noise of ∼5 at 23 AB magnitude (Seibert & Schiminovich, in prep.).
