New Milky Way companions found: SDSS-II first to view two dim dwarf galaxies

  

The figures are created from SDSS-II images. Each star in the photometric database is assigned a color and plotted as to the star's brightness. These images are filtered by selecting stars whose colors and magnitudes are characteristic of the stars in each galaxy.
