A Galaxy on Edge

NGC 2188 is estimated to be just half the size of our Milky Way, about 50,000 light-years across.  Although we see it on edge, astronomers have determined that it’s a barred spiral galaxy by studying the distribution of the stars in the inner central bulge and the outer disk and by observing the stars’ colors.

NGC 2188 in the constellation Columba (the Dove). That constellation was named in the late 1500s after the dove that brought an olive leaf back to Noah’s ark. Coumbia a small constellation with many faint yet beautiful stars and astronomical objects.
