“Baade's Red Sheet” Resolved into Stars with Hubble Space Telescope in the Blue Compact Dwarf Galaxy VII Zw 403

Hubble Space Telescope Wide Field Planetary Camera 2 observations of the nearby blue compact dwarf galaxy VII Zw 403 (=UGC 6456) resolve single stars down to MI ≈ -2.5, deep enough to identify red giants. This population has a more uniform spatial distribution than the young main-sequence stars and supergiants, forming the structure known as "Baade's red sheet." We conclude that VII Zw 403 is not a primeval galaxy.
