Point of view is everything.
Galaxy NGC 2188 is a barred spiral, but as this @NASAHubble Space Telescope image shows, only its very narrow outer edge is visible to us on Earth. The center and spiral arms of the galaxy are tilted away from us, with only the very narrow outer edge of the galaxy’s disk visible to us. Astronomers liken this occurrence to turning a dinner plate in your hands so you see only its outer edge. The true shape of the galaxy was identified by studying the distribution of the stars in the inner central bulge and outer disk and by observing the stars’ colors.
NGC 2188 is estimated to be just half the size of our Milky Way, at 50,000 light-years across, and it is situated in the constellation of Columba (the Dove).
