We find that NGC6789 is the most nearby example of a Blue Compact Dwarfgalaxy known to date. With the help of WFPC2 aboard the Hubble Space Telescope,we resolve NGC6789 into over 15,000 point sources in the V and I bands. Theyoung stars of NGC6789 are found exclusively near the center of the galaxy. Thered giant population identified at large galacticentric radii yields a distanceof about 3.6 Mpc, a stellar metallicity [Fe/H] of about -2, and a minimum ageof about 1 Gyr. Despite its isolated location in the Local Void,its lowmetallicity, and its active star formation, the properties of NGC6789 areclearly not those of a galaxy in formation.Comment: 8 pages, 4 figures, ApJL Accepte
