Description:

NGC 891 is a class SA galaxy in the constellation Andromeda. It lies at a distance of about 30 million light-years. We see it nearly perfectly edge-on, which casts its dust lanes, with numerous vertical projections, in silhouette against the galaxy's yellow central bulge and peripheral blue spiral arms. Interestingly, this same dust would render our own Milky Way galaxy invisible from within NGC 891.
