NGC891 is an edge-on spiral galaxy thought to be about the same size and shape as our Milky Way. Located in Andromeda, the galaxy is about 30 million light years away. While we see the galaxy edge-on, the Milky Way would be nearly impossible to view from NGC891 for the same reason we cannot see (in the visual spectrum) through the dust lanes and stars of our own galaxy (called the Zone of Avoidance).
