The Stars of the Orion Arm

We have now reached the edge of the flattened disk of the Milky Way, about 3000 light years thick at the Sun's 30 000 light-year distance from the galactic center. Almost every star of the thousand mapped by the old watchers of the sky, those who first gathered stars into constellations, lies within this square, our own galactic neighborhood. As we draw ever closer to the Sun, we are able to see more and fainter stars. In the preceding images, seen from the emptiness to the north of the Milky Way, only the brightest and largest of the stars were visible.
