We find that NGC 6789 is the most nearby example of a Blue Compact Dwarf galaxy known to date .
With the help of WFPC2 aboard the Hubble Space Telescope , we resolve NGC 6789 into over 15,000 point sources in the V and I bands .
The young stars of NGC 6789 are found exclusively near the center of the galaxy .
The red giant population identified at large galacticentric radii yields a distance of about 3.6 Mpc , a stellar metallicity [ Fe/H ] of about -2 , and a minimum age of about 1 Gyr .
Despite its isolated location in the Local Void , its low metallicity , and its active star formation , the properties of NGC 6789 are clearly not those of a galaxy in formation .
