But as a small sample, HDST will transform studies of the most distant bodies within our own Solar System, elucidate complex chemistry within the nearest stellar populations, robustly measure of the masses of new stars, map panoramic high - resolution images of star formation in the vicinity of supermassive black holes, and trace detailed motions within the smallest, dark - matter - dominated galaxies.
