I have seen several very impressive stitched images of the Milky Way that presented the galaxy as it would appear to someone outside the disc of stars and dust we call home. Actually, the Milky Way is made up of several arms, and if one is in the right position between two of those arms, one would actually see both arms, one in front and one in back. Our sun is in the Orion spur between the Scuttum-Centaurus arm and the Perseus arm, with the thinner Sagittarius arm passing across the view of the Scutum-Centaurus arm. Therefore, if we were out in space without the earth to block our view, shouldn't we be able to see the Perseus arm behind us if we do a 180 away from our view of the galactic core? Can the astronauts in the ISS see these arms?
